Appendix C: Chapter 2 Connecting Sensors to the

Nova5000

Before you start using the MultiLab software, you should first familiarize yourself with the Nova5000 sensor interface.

Note: You are able to choose from over 65 Fourier sensors, 20 Vernier sensors, and 8 Data Harvest sensors to connect to

the Nova5000. See page 109 for a full list of supported sensors.

Sensors are connected to the 4 (I/O) sockets situated on the top of the Nova5000. These ports are labeled I/O-1 to I/O-4, as shown

below. All four sockets can be used simultaneously.


To connect a sensor to the Nova5000 you must use a Fourier mini-din cable.Plug one end of the cable into the Nova5000 with the arrow

facing down, and the other end into the sensor.

If you are using one sensor only connect it to I/O-1. If you are using two sensors connect them to I/O-1 and I/O-2, and so on.

Note: The mini-din cables are not included with the Nova5000 device and must be purchased separately.

Connecting more than 4 sensors at a time


The Nova5000 will support the connection of up to 8 sensors simultaneously.

In order to connect more than 4 sensors at a time, you will need to use one or more splitter cables.

Using a splitter cable

To connect a splitter cable, first connect to the end of the cable with a single plug with two arrows to one of the Nova5000 I/O ports. The other end of the cable has two plugs which are marked. One is

marked with two arrows and the other is marked with the letter “S”.

The cable marked with the arrows is the main cable input which, when connected to a sensor, is assigned the lower I/O number on the Nova5000. The second plug is marked with the letter S (Split)

indicating that it is the secondary input (the higher I/O number).

Example: If you plug the splitter cable into I/O 1, the cable with the arrows is assigned I/O 1 and the cable with the “S” is assigned I/O 5.

I/O-4 splits into I/O-4 and I/O-5





Note: Before connecting the mini-din cable to the Nova5000 or the sensor sockets, make sure that the mini-din plug is correctly positioned in front of the socket. Connecting the cable in an awkward position might cause damage to the

cable pins.

Connecting Vernier and Data Harvest Sensors

If you are using a Vernier or Data Harvest sensor, first consult Appendix A to ensure that this sensor is supported by the Nova5000.

You must also have the Vernier adapter supplied by Fourier in order to connect Vernier sensors to the Nova5000 sensor interface.

Data Harvest sensors require no adapter and connect directly to the Nova5000.

For MultiLab to recognize third-party sensors, you must define them in the software using the Define New Sensors option. Please refer to

section 4.8

Chapter 3 – Operating MultiLab 19

1.6 3.2 Viewing Data

As previously mentioned MultiLab features three views for viewing recorded data: Graph, Table and Meter. You can easily switch

between these views using the corresponding buttons on the main toolbar.

Once you have completed your experiment you can view the recorded data offline in Graph or Table view.

Meter view has a snapshot mode that will allow you to see the reading at the cursor’s location on the graph.

D.1.10. 3.2.1 Data Map

The Data Map is situated on the left of the MultiLab window and lists the data sets that were recorded in the current MultiLab session. The Data Map is populated by running experiments or opening previously

saved data sets.

A data set contains all data recorded in a particular experiment. Each sensor used in the experiment has its own entry in the data set, and you can toggle which data, if not all, to display in the graph or table.

When you apply analysis functions onto your data, an entry for that specific function is also added to the Data Map.

When using the Data Map, the following actions can be performed:

To display the complete list of sensors measurements for an individual experiment, tap the plus sign (+) next to the experiment entry to

expand its data set To collapse the sensor list under an individual experiment, tap

the minus sign (-) next to the experiment entry

To display a specific data set tap its name in the list, and then tap Show situated at the bottom of the Data Map. You can also

choose to display data from specific sensors in the data set. Simply tap the sensor name and tap Show


To hide a data set tap its name in the list, and then tap Hide situated at the bottom of the Data Map. You can also choose to hide data from specific sensors in the data set. Simply tap the

sensor name and tap Hide

D.1.12. 3.2.3 Graph View – Y-Axis

One sensor:

If there is only 1 sensor connected to the Multilab software, you will see the Y-axis on the left hand side.

36 Cha

Two Sensors:

If there are 2 sensors connected, you will see 2 Y-axis, one on the left and one on the right.

The Y-axis on the left represents the 1st sensor, and the y-axis on the right represents the 2nd sensor.

In this case, the Magnetic Field sensor is on the left (1st sensor) and the temperature is on the right (2nd Sensor).

Three or more sensors:

If there are 3 or more sensors connected to Multilab, you will see 2 Y-axis, one on the left and one on the right.

The Y-axis on the left represents the 1st sensor, and the y-axis on the right represents the 2nd sensor.

To see the 3rd ,- 8th sensor, you must tap on data on the graph for the sensor you wish to view that specific Y-axis.


Here we have tapped on the Magnetic Senors data.

Since it is the 1st sensor it’s y-axis will always be displayed on the left.

Here we have tapped on the CO2 Sensors data. Since it is the 2nd sensor, it’s y-axis will be displayed on the right.

38 Cha

Here we have tapped on the Temperature Sensors data. Since it is the 3rd sensor, it’s y-axis will be displayed on the right.

Tapping each sensors data (Sensors 2-8) will reveal the y-axis on the right. By tapping each sensor data, you will be alternating which y-axis senor data is on the right side of the graph.

D.1.13. 3.2.4 Table View

Tap Table to display the data table.

The data that is displayed in the Table view always matches the data in the Graph view: each sensor Input is represented by a separate

column in the table.

Use the Data Map to change the data that is displayed in the table. You can see below the table view along with other views in Multilab.


Add Manual Column You can manually add a new data set to a data table, even after the

experiment has been conducted. You can then view this data set as a plot line in Graph view:

From the Tools menu, select Add Manual Column.

40 Cha

In the Insert manual column dialog box, enter the column title and column unit.

On the data table, manually enter data into the newly created column.

In the Data Map, select the new data set and tap Show.

D.1.14. 3.2.5 Meter View

Meter View consists of the following views. Switch between views by tapping the corresponding icon on the Meter toolbar situated below

the Meter View window.

Analog view

Bar view

Color view

Digital view

Switch views

The Switch Views feature allows you to switch between single and multi view.

MultiLab enables you to view data in Meter format in the main MultiLab

window. In Meter view, you will see real-time data readings from the sensors currently connected to MultiLab.

You can see below the Meter view along with other views in Multilab.


Use Meter view to:

View live data without actually recording this data i.e. to monitor the current real-time sensor readings (Snapshot mode)

View data in real-time while it is being recorded by MultiLab (Run mode)

The meters’ scaling automatically matches the graph’s scaling.

While viewing or collecting data in Meter view, you may view data from up to four sensors at a time. If you have more than one sensor connected, switch between these sensors on-the-fly using the drop-

down sensor menu located above the Meter view.

To select the Meter view, tap the Meter icon in the main toolbar.

The Single Meter view or Multiple Meter view window will open, depending on which view you were in last.

42 Cha

Single Meter view Multiple Meter view

In Single Meter view, you can select the sensor to be displayed via the drop-down menu at the top of the screen. Change the specific

Meter view via the icons at the bottom of the screen.

In Multiple Meter view, tap on one of the four panes within the window and select the sensor to be displayed via the drop-down

menu at the top of the screen. Change the specific Meter view via the icons at the bottom of the screen.

Toggle between Single and Multiple views using the icon.

Snapshot Mode In Snapshot mode, MultiLab continuously displays the real-time data

but the data is not actually saved i.e. a snapshot of the data is

displayed. A small camera icon indicates you are in Snapshot mode, and is located on the bottom left of the Meter window.

To work in Snapshot mode, simply connect your sensor and switch to Meter view. As long as you don’t tap Run, you will remain in Snapshot mode and MultiLab will display the sensor data. MultiLab will display

the data at a sampling rate of one sample per second.

Note: When using a temperature sensor in snapshot mode,

you can change the temperature units from Celsius, Fahrenheit, or Kelvin in the preferences window.

deleted manually.

52 Chapter 4 – C

Appendix F: Chapter 4

Appendix G: Configuring Sensors in MultiLab

This chapter provides further details on using sensors with MultiLab, including setting up sensors, calibrating sensors, and other important

information.

1.12 4.1 Choosing the Right Setup

G.1.1. 4.1.1 Sampling Rate

The sampling rate should be determined by the frequency of the phenomenon being sampled. If the phenomenon is periodic, sample

at a rate of at least twice the expected frequency. For example, sound recordings should be sampled at the highest sampling rate –

20,000/sec, but changes in room temperature can be measured at slower rates such as once per second or even slower, depending on

the speed of the expected changes.

Note: Sampling at a rate slower than the expected rate can cause frequency aliasing. In such a case, the graph will show a frequency much lower than expected. In the figure below, the higher frequency sine wave was sampled at 1/3 of its frequency. Connecting the sampled points yielded a graph

with a lower, incorrect frequency.

Chapter 4 – Configuring Sensors in MultiLab 53

Frequency aliasing

After you have chosen the sampling rate, choosing the number of points will determine the logging period:

Samples / Rate = Logging time.

You can also choose the duration of an experiment first, and then calculate the number of samples:

Samples = Logging time Rate.

G.1.2. 4.1.2 Manual Sampling

Use Manual sampling for:

Recordings or measurements that are not related to time Situations in which you have to stop recording data after each sample

obtained, in order to change your location, or any other logging parameter

Note: During the experiment no changes can be made to the MultiLab sensor configuration.

To start an experiment using manual data logging:

Go to the Rate tab in the Setup Wizard

Select Manual from the Rate drop-down menu

Tap Run once to record the first sample. Tap Run again to record the next data point, and so on

54 Chapter 4 – C

To stop the Manual data logging session, go to the Logger Menu and select Stop

1.13 4.2 Ohaus Scale

The Nova 5000 is able to support a digital Ohaus scale connected via USB.

G.1.3. 4.2.1 Connecting the scale

1. Plug the scale to an outlet using the provided adapter 2. Plug the scale to one of the Nova's USB ports 3. Turn on the scale and zero it if the scale is not reading 0.00 4. Run the Multilab Software

Note: You must have the Ohaus digital scale on and connected prior to running the Multilab Software. Otherwise

the scale will not be detected

5. Connect any sensor to IO/1. A sensor must be connected for the scale to work properly

6. Go to the Logger menu and choose Setup 7. Mark the checkbox for Ohaus External Scale and tap the

Properties box


Note: You can only select the Ohaus External Scale if a scale is connected and detected by the Multilab software.

G.1.4. 4.2.2 Configuring the Ohaus scale

1. In the properties windows, you can select the scale range and unit

Range: You can choose the scale type, if it is a 0-200

gram scale or a 0-400 gram scale Unit: You can select the unit of measurement from

grams, ounces, pounds, kilograms, or Newtons

56 Chapter 4 – C

2. Tap the OK button to confirm your settings or CANCEL to exit out without saving.

3. Back to the setup window, tap the rate you wish to log the experiment at.

NOTE: The Ohaus Scale will not work at rates higher than once per second. If you are logging at a rate of more than

every second, the Ohaus scale will report values of identical data. Example: If you have it set a 10 samples per second, the

Ohaus scale will report the same values in batches of 10.

4. Tap the samples tab to configure the amount of samples you wish to take and then tap on the OK button to save your settings.


5. The Ohaus scale can be used in 2 ways, items can either be placed on the plate, or hung from a hook at the bottom of the scale.

G.1.5. 4.2.3 Running an experiment with the Ohaus scale

1. To run an experiment you can tap the run icon or you can tap the Logger menu and choose Run.

2. When you begin logging, you will see the Ohaus Scale show up as another sensor.

1.14 4.3 Programming Rules and Limitations

The following are some rules and limitations you must take into account when programming sensors for use with the Nova5000.

MultiLab integrates all programming limitations automatically and will only allow the programming of settings that comply with the rules

below.

G.1.6. 4.3.1 Number of Sampling Points

Increasing the number of active inputs limits the number of sampling points one can choose. The following condition must always be

satisfied:

Samples Active Inputs < Memory

58 Chapter 4 – C

The Nova5000’s data logger memory is sufficient for 100,000 samples. However, when sampling at rates faster than 100 samples per second, the memory can store only two experiments of 32,000 samples each.

Selection of 100,000 sampling points will create 2 files of 50,000 points each in the data logger’s memory.

1.15 4.4 Setting the Zero Point of a Sensor

4.4.1 Compatible Sensors

MultiLab enables you to rescale some sensors and to set the current readings to zero for subsequent loggings. This feature applies to

sensors such as:

CO2 Distance

Force Magnetic field

Light Pressure

Spirometer

Note: Not all senors have the Set Zero function

To set the current readings of a sensor to zero:

Tap Setup on the main toolbar to open the Setup Wizard.

Comment [EM6]: It's a part of the sensor proprieties so it should appear in the relevant section and not here/


Tap the Sensor properties icon next to the sensor input you want to set.

Tap the Set Zero tab.

Check the Set the current reading to zero checkbox.

Tap OK, and tap OK again to exit the Setup window.

MultiLab takes a single measurement and sets the reading to zero.

4.4.2 Change the zero point

MultiLab allows you to change the zero point of a sensor. In certain experiments this can be very helpful.

1. Tap Setup on the main toolbar to open the Setup Wizard.

2. Tap the Sensor properties icon next to the sensor input you want to set.

3. Tap the Set Zero tab.

4. Tap the Reset zero button.

5. Tap OK, and tap OK again to exit the Setup window.

4.4.3 Return to the default zero point

After your experiment is finished, you may want to use the senor differently and need to set the sensor back to default.

1. Tap Setup on the main toolbar to open the Setup Wizard.

2. Tap the Sensor properties icon next to the sensor input you want to set.

3. Uncheck the Set the current reading to zero checkbox.

4. Tap OK, and tap OK again to exit the Setup window.

Comment [o7]: Both this section and the next one are missing an introductory paragraph (i.e., “MultiLab allows you to do so-and-so. To do this, you must do the following:”)

60 Chapter 4 – C

1.16 4.5 Triggering

Triggering allows you to set a set of values that will allow the experiment to begin recording only when those values are met.

Tap Triggering on the Samples tab of the Setup Wizard. This opens the Triggering dialog box:

Select the triggering sensor in the Based on drop-down menu

Choose one of the following from the Type options:

None - Triggering is disabled Above level - Start logging only once the measured value is higher than the trigger level Below level - Start logging only once the measured value is lower than the trigger level Event Recording - This function enables you to record the exact time and date at which a certain phenomenon occurs. The trigger level set for this option is actually a threshold setting. Each time the threshold is crossed, MultiLab will record the exact time and date of the occurrence, and will

Comment [EM8]: It's a part of the sensor proprieties so it should appear in the relevant section and not here/


continue to do so until the desired number of samples has been obtained

Note: The trigger acts on analog measurements only (not on the distance sensor). The trigger condition must be fulfilled

for at least 300S.

Control Level - The control level trigger allows you to create an automatic sense & control system. Tap OK to exit the Triggering dialog box. Tap OK again to exit Setup

Wizard.

4.5.1 Control Level The control level trigger allows you to create an automatic sense & control system. This means that you can connect a sensor measuring a certain phenomenon and set a value on when an event will be triggered. Example: Using a fan that will start operating when the temperature measured by the sensor rises above 30 ˚C). The control level function requires the use of a splitter cable and a control sensor. The cable divides each input into a sensor cable and a controller cable. After setting the control level and starting the data logging process, the sensor will sample and record the data as usual. However, when the measurement from the sensor rises above the predetermined threshold value, the controller cable will send a pulse of 5V to the control sensor, and will continue to do so until the sensor measures a value below the threshold level. When receiving the 5V pulse, the control sensor will close/open a relay capable of switching 110/220V to any load.

Comment [D9]: SCREENSHOTS!!!

1.17 4.6 The Timing Wizard

MultiLab enables you to measure events such as Time, Velocity and Acceleration using the photogate sensor and the Logger Timing

Wizard.

4.6.1 Working with the Timing Wizard Connect one photogate to I/O-1 of the Nova5000, or two photogates,

one to input I/O-1 and the other to I/O-2, depending on the type of data you require.

Note: There is not a “Photo Gate” sensor entry, the Photo Gate sensor displays as “Voltage 0-5V”

From the Logger menu, select Timing Wizard to open the Timer Module Wizard.

Select one of the options for measurement: Time, Velocity or

Acceleration.

Tap the Timing Wizard – Method tab.

Comment [EM10]: This is a working mode . we should write an introduction describing all the working modes with the multilab: Record a new experiment Open a saved experiment Manual x axis mode Timing wizard module Analysis timing wizard Playing video experiment Workbook mode Data analysis


Select one of the options to select the measuring method.

If required, enter the body’s width in mm (an integer between 0 to 59), or the distance between the gates in cm (an integer between 0 to 99) in the text box (for velocity and acceleration measurements

only).

Tap OK to exit the Timing Wizard and tap Run to enter the timing standby mode.

Timing begins each time a body blocks the photogate in input 1 and ends when a body blocks the photogate in input 2 2 (according to the event method). MultiLab displays the results in a bar graph and in the

data table.

You can record as many measurements as you need. After each event, MultiLab adds the results as a new bar in the graph and as new

raw data in the table.

To exit the timing mode tap Stop on the main toolbar.

4.6.2 Measuring Methods

The Timing Wizard offers you various methods of analyzing the different measurements. In some measurements you will be asked to enter the width of the moving body, or the distance between the two photo gates, to allow for the calculation of velocity and acceleration.

The methods depend on the selected measurement:

1.18 4.7 Calibrating Sensors

Though Fourier's sensors are shipped pre-calibrated from the factory, you may choose to manually calibrate the sensors in order to increase their accuracy on-site. This can be done using the various calibration

techniques provided by MultiLab.

Most of the Fourier sensors are linear, i.e. the output level of each sensor changes according to the equation:

Where:

Y - Output of the sensor (voltage level changing from 0 to 5V)

X - Sensor input

a - Sensor gain

b - Sensor offset

The calibration process allows you to control the offset, and in some cases even the gain, of a sensor. You can perform four types of

calibration:

Hardware offset calibration MultiLab Automatic zero calibration

MultiLab Sensor calibration Factory calibration (no manual calibration required)

G.1.7. 4.7.1 Hardware Offset Calibration

Some of the sensors include a screw which controls the sensor offset. To calibrate the sensor, use MultiLab to run an experiment with the sensor and rotate the calibration screw until the sensor shows the

correct measured value (obtain the actual correct value from another source that is known to be accurate).

baXY

68 Chapter 4 – C

G.1.8. 4.7.2 Nova5000 Automatic Zero Calibration

The Nova5000 data logger is able to automatically calibrate the sensor offset for all analog sensors accurately, quickly, and for every

new experiment conducted.

The calibration method is very simple. Whenever you plug in a sensor, the data logger checks to see if the selected sensor measures a value within 2% of its zero value. If so, MultiLab sets that value as

zero.

To enable this feature, make sure that the sensors are at their zero values when you plug them in. To ensure the most accurate zero

value:

Shorten the Voltage sensor plugs Leave the Current sensor plugs open

Cover the Light, Photogate, and Microphone sensors Insert the pH sensor in a pH 7.0 solution

Unload the Force Transducer Place the Accelerometer on a stationary surface

Place the Temperature probes in ice water Place the Pressure sensor in a 1 ATM (1013 mb) chamber

G.1.9. 4.7.3 pH Temperature Compensation

To compensate a pH sensor for temperature changes, plug the temperature sensor into I/O-1, and the pH sensor in I/O-2. MultiLab

will then display the compensated pH value.

G.1.10. 4.7.4 MultiLab Sensor Calibration

MultiLab enables you to calibrate any of the linear sensors manually. This two point calibration method sets both the gain (slope) and offset

(intercept) of the sensor’s conversion function. The calibration procedure affects MultiLab readings only.


In the Logger menu, tap Calibrate Sensors.

Select a sensor from the Choose Sensor drop-down menu and tap OK.

Enter a distinct real value in each of the Real Value fields (in the unit of the specific sensor) and the corresponding measured values in

each of the Measured Value fields (in the unit of the specific sensor). The measured values are the values displayed by

MultiLab when measuring the two real values.

Tap OK. The calibrated sensor parameters will be saved in MultiLab

To reset to the default calibration for any sensor, repeat steps 1 to 2 above and tap Restore defaults, then tap OK to complete the

process.

G.1.11. 4.7.5 Factory Calibration (No Calibration Required)

All digital sensors that are essentially timers leave the factory fully calibrated, and do not suffer from any accuracy degradation. An

example of such a sensor is the Sonic Ranger distance sensor, which measures the time passed from the transmission of a sound pulse to

its echo reception.

70 Chapter 4 – C

1.19 4.8 Defining New Sensors

MultiLab enables you to define additional custom sensors. This is a useful tool for when you need the Nova5000 and MultiLab to

communicate with sensors from different sensor vendors, such as Vernier.

Any additional sensor that you would like to connect to the Nova5000 must comply with the following restrictions:

The sensor’s output must be between 0-5 volts. The sensor Transfer Function (sensor output voltage changes vs. the sampled phenomenon changes) must be a linear Transfer Function The sensor must have a code resistor in order to be automatically

identified. If the sensor does not have a code resistor, you will have to work in 8-sensor mode and select the sensor manually

To determine whether or not your sensor has a code resistor, simply connect it to the Nova5000, open MultiLab and enter the Setup

Wizard, then verify that the sensor is displayed in the Sensors tab.

Refer to page 116 to learn how to add a code resistor to your custom sensor.

To define a new sensor From the Logger menu, select Define New Sensor to open the

Define New Sensor dialog box.


Tap Add new sensor.

Enter a sensor name and a measurement unit in the relevant fields.

Enter the sensor output in Voltage, in the Output Value #1 and Value #2 fields.

Enter the corresponding real sensor values, in the unit of the custom sensor, in the Real value fields.

Tap OK. Your sensor has now been defined and is saved in the Sensor list in the Setup Wizard.

Tap Restore defaults to restore the default sensor list, and remove the defined sensors from the Setup Wizard sensor list.

5.3 Timing Analysis Wizard

The Timing Analysis Wizard is an additional analysis tool, which enables you to easily measure and calculate many types of time events, including velocity and acceleration, with one or two photo

gates.

Connect one photogate to input 1 of the Nova5000 or connect two photogates to input 1 and input 2 of the Nova5000 and perform the

desired experiment. Then let the wizard guide you through the analysis of this experiment.

Using the Analysis Timing Wizard, you can measure sequences of time events at either gate, or between the two gates. MultiLab can

then calculate the velocity and acceleration of these events. Special options make it easy to measure velocities in collisions and the time

period of a pendulum or any other oscillating body.

The Analysis Timing Wizard can handle multiple events. For example, if a body crosses a photo gate several times, applying the wizard will

result in a series of measurements that match the number of crossings.

I.1.1. 5.3.1 Working with the Timing Analysis Wizard

Display the data that you wish to analyze in the Graph window.

12GC


On the Tools menu, select Analysis, then Timing Analysis. This launches the Timing Wizard dialog box.

Select the Time, Velocity or Acceleration measurement.

Select the Timing Wizard – Method tab.

Select one of the measuring methods: At one gate, Between gates, or

Collision (two gates).

If required, enter the body’s width, or the distance between the gates in cm in the Width text box.

Tap OK to display the results.

I.1.2. 5.3.2 Measuring Methods

The Analysis Timing Wizard offers you various methods of analyzing the different measurements. Some methods will require you to enter

82

the dimension of the moving body, or the distance between the two photo gates, to allow for the calculation of velocity and acceleration.

The methods depend on the selected measurement:

Time

At one gate


cross the photo gate (between blocking and unblocking the infrared

beam)

Between gates



photo gate (between blocking the first and blocking the second

infrared beams)

Pendulum

Measures the time period of an oscillating body (the time interval between the first and the third blockings of

the beam)

Velocity


At one gate


cross the photo gate (between blocking and unblocking the infrared beam) and returns the

velocity.

Requires you to enter the body’s width.

Between gates



photo gate (between blocking the first and blocking the second infrared beams) and returns the average

velocity.

Requires you to enter the distance between

gates.

Collisions

Measures the crossing time

intervals at each gate and returns the corresponding

velocities.

Requires you to enter the bodies’ width (the

width of the two bodies must be

84

identical).

Acceleration

At one gate

A card with two flags must be attached to

the moving body (see figure to the left). The

Timing wizard measures the crossing time

intervals of the two flags and returns the

acceleration.

Requires you to enter the flags width.

Between gates

Measures the crossing time at the first gate, the time it

takes the body to move from one gate to the second gate

and the crossing time at the second gate

and returns the average acceleration.

Requires you to enter the body’s width.

I.1.4. 5.3.4 Tips On Using the Timing Wizard and Timing Analysis Wizard.

Attach a flag to the moving body When measuring the motion of a moving cart, it is convenient to

attach a vertical flag to the cart (see picture below). You can mount a slotted wooden block on the cart and insert the flag onto the slot, or

use masking tape to attach the flag to one side of the cart.

Use a double flag to measure acceleration at one gate. The width of the two flags must be the same.

Moving the cursor:

For finer cursor movements use the forward and backward buttons on the graph toolbar.

It is also possible to tap anywhere on the graph’s plot to move the data point.

When there is only 1 data point selected; the coordinate values of the selected point will appear at the bottom of the graph window.


When there are 2 data points selected; the differences between the 2 points will appear at the bottom of the graph window.

dX refers to the value between the X axis of the 2 points. dY refers to the value between the Y axis of the 2 points.

Here we can see that that dX value is 3800 ms representing the number of seconds between points 1 and 2. Also the dY value is 0.01

V representing the amount of Voltage between points 1 and 2.

Appendix S: Adding a Code Resistor to a Custom

Sensor

In order for the Nova5000 to automatically identify a sensor, it must have a code resistor. The figure below shows the Nova5000 input

socket configuration.

You must connect the resistor between the Auto recognition resistance input and the GND input.
