6. Let the new sensor stabilize for at least 5 minutes then refer to the FIELD CALIBRATION PROCEDURE section to zero and

Sensor Life Reset
1. Remove the Philips screw on the front of the TX-12-ND. Pull the front cover of the unit off.
2. To reset the sensor life (rSt), from normal or warm-up mode, press the Next button four times to get to SEn or Sensor Mode.
3. Then press the Enter button to get to "rSt" - Reset Sensor Mode.
4. Press the Enter button again to see the sensor reset status. If the sensor life has already been reset, done "don" will be displayed.
If it has not already been reset, "no" will be displayed. Push Next to change it to "YES" (flashing) then push Enter to confirm the
change (solid) and push Enter again to return to "rSt" in the SEn menu. Push Next until "End" is displayed then push Enter to get

NOTE: If the sensor is reset and not replaced it is necessary to test and/or calibrate the sensor to assure that it is still performing within
acceptable specifications though the sensor is nearing the end of its 2-3 year expected life. There will be no other indication of sensor
performance.
Do not disassemble unit or attempt to repair or modify any component of this instrument. This instrument contains no user serviceable
parts, and substitution of components may impair intrinsic safety, which may adversely affect product performance and result in
sickness or death.
CAUTION
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may permanently scratch the surfaces
and damage the display window, labels, sensor or instrument housing.
Cleaning
Cleaning of the external surfaces is best carried out using a damp cloth with a mild detergent or soap. Use a vacuum cleaner with soft
brush to remove dust or contamination under the cover. Do not blow out the sensor with compressed air.
TESTING
Using a certified gas with a concentration other than the one listed for this detector when conducting a calibration or calibration
verification test (bump test) will produce inaccurate readings. This means that higher levels of the gas being monitored may be present
and could result in overexposure and cause sickness or death. For proper use, see supervisor or User Instructions, or call Technical
Service at 1-877-367-7891
