Using the Transmitter
How to Program the Transmitter
The 301W sensors are designed to be maintenance free and do not
require calibration. The following calibration procedures (Functions 7
and 8) are provided as an exceptional troubleshooting measure.
Function 7 - Adjust Sensor Zero
• Press pushbutton 1
• Press pushbutton 2, count 8 blinks and release.
• Begin emitting the calibration gas
• Press pushbutton 1.
Note: Never calibrate any unit’s Zero with ambiant air. Always use
Nitrogen (N
2
) at the calibration port to calibrate the Zero.
Once this function has been executed, the LEDs will display the result:
Success: Both LEDs blink simultaneously 7 times, for three cycles.
Failure:
LED 1 blinks 7 times, for 3 cycles while LED 2 blinks non-
stop throughout the cycles.
Function 8 - Adjust Span
Allows you to calibrate the sensor’s span. Remember to begin emitting
the calibration gas before starting the calibration.
• Press pushbutton 1
• Press pushbutton 2, count 9 blinks and release.
