MONITOR CONFIGURATION: CONFIG MODE While the Smart Monitor is in the Normal Gas Monitoring Mode, by pressing and holding the [CONFIGURE/4] Key for two seconds, the operator can access the configuration programming, CONFIG MODE, for the monitoring device. Provided a correct User Access Code is entered, a list of the configuration functions can be accessed that define all of the necessary programming parameters and settings for the monitor. A System Access Code of “111” may be used at any time that the program asks for the Access Code. Once the correct User Access Code is entered, the message “CONSPECV20D” will continuously scroll across the liquid crystal display (LCD). The operator should press the [CONFIGURE/4] Key once to confirm. The LCD will show “000” and wait for the operator to enter the desired configuration function code. The operator can use the Keys [1], [2] or [3] to increment/decrement the LCD display to the desired function code number. Key [4] can be used to toggle the increment/decrement mode. Below is a list of the Configuration Functions and associated Code Numbers:

AUTO CALIBRATION A soft touch keypad and liquid crystal display (LCD) is provided on the front cover of the enclosure for calibrating the P2031-KP, Oxygen (O2) Monitor. Regular calibration and testing is mandated to ensure the sensor is operating properly. To calibrate the Oxygen (O2) sensor, follow the procedures below:

1. Press the [CALIBRATE/5] Key and hold until the display scrolls the message “ENTER ACCESS CODE”. Press the [4] Key one time, to stop the scrolling of “ENTER ACCESS CODE”. Three Zeros will appear on the display “000” The program is waiting for the input of the User Access Code from the keypad. Press Key [3] for the ones Press Key [2] for the tens Press Key [1] for the hundreds Press Key [4] one time to reverse the number Press Keys [3], [2] or [1] to change the number The default User Access Code from the factory is “001”. After the Access Code is entered, press the [4] Key two times to accept.

2. The RED “SPAN” LED turns ON and will stay on for the duration of SPAN calibration.

3. Inject the span gas (typically 20.9% oxygen, O2) into the sensor via the calibration fitting at a

flow rate of 0.5 LPM.

4. Maintain the flow of the span gas to the sensor for as long as the RED "SPAN" LED is turned ON.

5. After the pre-defined span calibration period, the RED "SPAN" LED will turn OFF, and the

GREEN “ZERO” LED will turn ON.

6. Remove the span gas, and inject the zero gas (100% nitrogen, N2) into the sensor via the calibration fitting at a flow rate of 0.5 LPM.

7. Maintain the flow of the zero gas to the sensor for as long as the GREEN “ZERO” LED is

turned ON.

8. If the calibration procedure is performed properly, the GREEN “ZERO” LED will turn OFF after the pre-defined calibration period. The new calibration data will automatically be stored to the EEPROM for future reference and the monitor will return to the normal gas-monitoring mode.

9. If the new calibration data differs from the previous data by more than 20%, both the "SPAN"

and "ZERO" LEDs will be turned “ON” for approximately five seconds. This indicates that the calibration was not performed properly or the sensor cell has deteriorated beyond calibration standards. The message “BAD INPUT” will scroll across the LCD and the previously stored data will be restored to memory.

10. An unaccepted calibration is normally due to either using the incorrect scale gas or the sensor

cell has become defective and is providing less than 75% of the previous calibration data. In the second case, the sensor cell should be replaced and the unit should be re-calibrated to ensure proper operation.

MANUAL CALIBRATION: FUNCTION “011” CAUTION: Do not enter Function “011” unless an actual gas calibration is to be performed. Stepping through Function “011” without applying the proper calibration gasses will render the device inoperable until a full gas calibration is completed.

Press the [4] Key and hold until the display starts scrolling, “ENTER ACCESS CODE”. Press the [4] Key one time, to stop the scrolling of “ENTER ACCESS CODE”. Three zeros will appear on the display “000” The program is waiting for an input from the keypad. Press Key [3] for the ones Press Key [2] for the tens Press Key [1] for the hundreds Press Key [4] one time to reverse the number Press Keys [3], [2] or [1] to change the number The default Access Code from the factory is “001” After Access Code is entered, press the [4] Key two times to accept. Press the [4] Key one time to stop the scrolling of “CONSPECV20D” Three zeros will appear on the display “000” Press Key [3] one time to make “001” on the display Press Key [2] one time to make “011” on the display Press Key [4] two times to accept. The message “ZERO INPUT” continuously scrolls across the LCD. Press the [4] Key one time to confirm “ZERO INPUT”.

The display will show the current ADC data, apply the zero gas (100% nitrogen (N2) gas) to the sensor via the calibration fitting at a flow rate of 0.5 LPM. Allow the displayed value to stabilize. This will take approximately two to three (2-3) minutes.

Press the [4] Key one time to accept the Zero Scale Gas reading.

Make sure the zero gas (nitrogen) is off.

The message “SCALE INPUT” and “FULL SCALE INPUT” scrolls across the LCD. Press the [4] Key once and select the correct gas input type as it scrolls across the

LCD. Use “SCALE INPUT” for any span gas less than full-scale gas.

Example: For a typical 2031-KP, Oxygen (O2) Monitor set at a monitoring range of 0-25%: 25% O2 is FULL SCALE GAS so select the “FULL SCALE INPUT” function. 20.9% O2 is SCALE GAS so select the “SCALE INPUT” function.

NOTE: Function “004” Calibration Input, should be set to the percentage of SCALE GAS (concentration of gas being used) to FULL SCALE GAS (sensor full scale range) rounded up to the nearest percent. For example, the input value of “084” [(20.9%/25%)=84%] would be used if 20.9% O2 span gas were being used as in the above example.

The display now shows the current ADC data value, apply the span gas to the sensor via a calibration fitting at a flow rate of 0.5 LPM. Wait until the value has stabilized, this will take approximately two to three (2-3) minutes. Press Key [4] one time to accept the reading.
