3. Check the pressure gauge on the regulator. If you have 25-psi or less you will need to replace the gas canister.
4. Place the test Hood from the regulator over the CO sensor.
5. Push Next 3 times to get to the CAL menu then push Enter. The display will flash back and forth between GAS and 200.
6. Start applying gas to the CO sensor.
Note: The sensor will look for the gas for 45 seconds. If no gas is applied or detected in that time, the display will return to CAL.
7. When the sensor detects the gas, the display will flash back and forth between the CO concentration and SPn, then the
calibration will progress and the display will show the gas level for a maximum of 165 seconds.
8. When the calibration is successful, the display will flash back and forth between CO concentration and PAS, then the display
will show the calibration gas level and the calibration is done.
9. If the calibration fails, the display will flash back and forth between the CO concentration and FAL (fail). If this occurs, check the
pressure gauge on the regulator. If the pressure is less than 25 psi the flow of gas may not be adequate to properly calibrate
the unit. If there is proper pressure in the cylinder repeat steps 4 through 6. If the unit fails to calibrate twice contact Technical
Assistance: 1-877-367-7891.
10. Once the calibration has passed, remove gas and disassemble the cylinder and regulator.
11. Re-assemble the CM-12 (make sure the LED is aligned with the front case hole). You are done.
12. See Calibration Flowchart on the inside of the housing.
