One of the unique capabilities of the FA Series force gauge is its ability to be mounted on a test stand.

The test stand is dual guiding cylinders with a 3mm pitch lead screw. Attached to the mounting bracket for the

scale are electronic calipers. The caliper reads to 8in (200mm). The calipers read in inches or millimeters

(push button select). It can be zeroed at any location on the caliper scale. Inches read to .001 and millimeters

read to .01.

1. The device has four screw holes on the back of its frame, which align with the mounting holes on the

test stand. Use the screws included with the test stand to mount the device to the stand.

* When using the test stand, make sure the device is secure, but do not over-tighten the screws as this

may damage the unit.

2. Once the force gauge is mounted connect a desired attachment.

3. If desired, other attachments can be connected to the base of the test stand.

4. To measure forces turn the knob on the test stand clockwise to raise the unit up and counterclockwise to

lower the unit down.

Note: The test stand’s knob moves the gauge 3mm, up or down, per full turn or rotation.

Chapter 6: Mounting Force Gauge on a Test Stand

1. Carefully take the force gauge out of the case.

2. Force Gauges with an external sensor require the bearings to be screwed into the load cell for support.

Note: If using the unit on a test stand refer to the chapter: Mounting the Force Gauge on a Test Stand.

3. Select a suitable tip in order to effectively conduct a measurement. (Choose the tip that will best

measure the force of the object being tested).

4. Slowly screw the tip onto the measuring rod at the top of the force gauge.

5. If necessary, connect the force gauge to a power outlet by plugging the AC Adapter into the 12V socket

at the bottom of the unit. Once the AC adapter is connected to the force gauge, plug the other end into a

wall socket.

Turning on the Gauge

1. Press the ON/OFF key to turn the device on.

As the device powers on it initializes itself. Do not move

or attempt to use the device during this process.

Note: To accelerate the initialization process, press the

MENU key. The results from the prior initialization will

be used.

2. Once the force gauge is turned on and has a suitable

tip attached for your measurement, align the device so

The Configuration options are used to set up general functions of the force gauge.

12.1 Measure Speed

This function allows the speed at which the device takes measurements to be adjusted. The measurement

displayed will increase or decrease at a faster or slower rate depending on the speed chosen. The speed allows

the user to obtain more or less readings during a measurement.

The speed should be chosen based on the object being

measured.

SLOW – will allow for slower measurements

FAST – will allow for faster measurements

12.2 Auto-zeroing

Auto-zeroing is used to prevent small amounts of force, resulting from unwanted variables, from affecting

measurements. This process is achieved when undesired measurements (e.g. vibration, movement, etc.) are

picked up by the force gauge, but immediately tared and therefore are not recorded.

Auto-zero uses the d setting to select the range up to

which the force gauge will not record.

The highest the auto-zeroing can be set to is 100 d. This

is 100x the smallest amount normally picked up by the

force gauge (i.e. 1.00N, 0.100kg, .100lb, 1.00oz).

The FA Series force gauges are designed for measuring the compressive/tension force in laboratory,

manufacturing, and quality control applications.

Measurements up to 200N can be performed by holding the force gauge in your hand.

For measurements above 200N it is strongly recommended that a double-hand handle is attached to the force

gauge (additional equipment).

The USB port allows for all measurement results to be loaded onto a computer for further analysis and

recordings.

After configuring the force gauge, take measurements by using the steps below:

1. Attach a tip suitable for the measurement about to be performed (i.e. pull, push, mass).

2. Turn the device on in the starting position (tare the device if necessary).

Note: If the device needs to be mounted to a test stand or has an external load cell, secure the device

for measuring.

3. If the intended measurements are to find out the push/pull peak force, the PEAK button should be

pressed to initialize the feature (press once for push peak, twice for pull peak).

Note: The force gauge with external load cell requires the PEAK button

be pushed once for pull force and twice for push force (opposite of the

internal force gauge).

13.1 Compressive Force (Push)

1. To measure the push force of an object, angle the device so it is linear to the object.

2. If measuring by hand grasp the device firmly.

3. Push the force gauge forward with the attached tip pressing into the object.

4. Study the measurements being recorded as the force is applied.

13.2 Tension Force (Pull)

1. To measure the pull force of an object, angle the device so it is liner to the object.

2. If measuring by hand grasp the device firmly.

3. Wrap the hook tip around the object and pull the force gauge away from the object.

4. Study the measurements being recorded as the force is applied.

* Do not exceed the gauges maximum capacity by more than 20%

All stored data can be viewed in STATS (Applications > Data Stored > Stats). From here you can view the

data in a histogram or chart. Stored data can also be saved to a computer for analyzing or printing.

* When you are packing the force gauge up, make sure to remove any attachments from the measuring

rod to prevent damage.

Calibration is an important step when weighing the mass of an object. This process is used to adjust the force

gauge or scale to the actual gravity and barometric conditions of the user’s current location. It also accounts for

any drift due to temperature changes. To get to this function go to the Main Menu.

There are multiple methods that can be used to calibrate the gauge:

- Use an object of known weight to correctly adjust the scale.

1. Position the device upside down with the hook tip

attached. The gauge should be secured in the same

fashion that you plan to use it to weigh objects in (e.g.

locked into a stand, by hand, etc.).

2. Set the Mode to Mass

3. Select the Load weight exactly equal to the weight of

the calibration weight that will be used to calibrate.

4. Place the calibration weight on the hook or hook-held

platform.

5. Select Calibration – START to initiate calibration.

- Input the g-value (gravitational acceleration) of the location where the force gauge is

being used.

For this method, the exact g-value must be known and can be typed in using the arrow keys.

Note: The g-value of a given location can be found on the internet. (e.g. Wikipedia, a municipality site, etc.)

- Input the Geographical Location of where the force gauge is being used.

If the g-value is not known, the geographical coordinates can be entered.

1. Select Geographic Location

2. Enter the Latitude of the current location

3. Enter the Elevation of the current location

By entering these coordinates, the g-value will automatically be updated therefore calibrating the device.

Note: The geographical coordinates of a given location can be found through multiple methods including:

A GPS, Smart Phone Apps, and the Internet.

- Input a Correctional Value

Errors may occur through extensive use and overloading of the force gauge. To account for these errors a

correctional value must be entered to adjust the force gauge.

Note: In order to perform a Correction an object with a known weight must be obtained.

1. Position the device upside down with the hook tip attached. The gauge should be secured in the same

fashion that you plan to use it to weigh objects in (e.g. locked into a stand, by hand, etc.).

2. Place the calibration weight on the hook or hook-held platform.

3. Find the difference between the actual weight and the measured weight of the object.

Note: The scale must be set to a unit of weight for this operation.

4. Select Correction and enter the difference.

By entering this value the force gauge will automatically be adjusted by calibrating itself.

* Factory calibration can be used to reset the force gauge to its default settings from its original

calibration at the manufacturer.

There are a number of errors caused by the user that will cause the force gauge to not work properly.

1. The force gauge should always be kept clean.

If dirt or dust builds up and gets in any of the opening of the force gauge, the software can begin

to malfunction.

2. Make sure no substances get stuck between the measuring rod and the frame of the device.

If anything gets wedged in this area, it can cause the measurements to become inaccurate and can

lead to permanent damage of the unit.

* If anything substances do get wedged inside, they should be removed using a tool which does not

conduct electricity.

3. Unauthorized personnel should not perform any repairs on the force gauge.

If anyone other than a trained technician tries to repair or adjust the force gauge, they can cause

permanent damage.

1. Get a damp cloth

2. Rub the cloth over the frame, key pad, LCD screen, and measuring rod.

3. Dry the force gauge off with a dry cloth.

* DO NOT pour liquid directly onto the force gauge.

* DO NOT attempt to clean the force gauge with alcohol.

* DO NOT wipe in the power socket or the USB port.

material such as film, paper, or foil. The vise

is equipped with an adjustable allen screw and

interlocking claps which allow for secure

sample griping without damage.

This chrome-plated manual C-Clamp is

designed to secure samples on the testing

stand. The clamp also easily attaches to the

force gauge and it is ideal for making

measurement on wide range of sample shapes

and sizes. This attachment should be used

when testing samples that need to be gripped

over a large surface area.

The roller grip attachment is used when

measuring tape strength as well as tape

adhesives. The grip is ideal for testing any

sample that needs to be draped in order to

obtain an accurate force measurement.

The two grip handle adapter is especially

useful when performing force measurements

between 200N and 500N. The handle securely

mounts the force gauge meter allowing users

a comfortable and firm grip when pulling ir

pushing objects that require extensive force.

The hook plate allows the TORBAL force
