Calibration: Exchange Method
(Estimate: 10 minutes/sensor)
1
Power off the unit.
2
Fit the new pre-calibrated sensor and PCB in place of the old
sensor and PCB. Set time delays if appropriate, and power
on the unit.
3
Carry out a bump test to confirm that the sensor is
responding.
4
Keep records of the test date, sensor serial number, and any
observations.

There are a number of advantages to sensor exchange. It is simpler and
quicker than gas calibration. Also, you avoid sensor end-of-life concerns.
