Calibrate the CO
This monitor is factory calibrated to a 400 PPM CO
Due to transportation, vibration, aging and other reasons, the CO
may get a zero drift and the detection accuracy may be reduced. In order to
restore the accuracy of the sensor, the automatic or manual baseline
calibration can be used to correct the drift.
Caution:
Do not calibrate the monitor in an environment of unknown CO
concentration.
Automatic baseline calibration
Your monitor is equipped with a smart chip so that it will automatically
calibrate itself to reduce the drift of the CO
starting after a minimum of 2 days. It will calibrate itself automatically at the
minimum CO
reading detected during 7 days of continuous monitoring.
