As with all measurement devices, co2mon.nz CO2 monitors must be calibrated to ensure the accuracy of their measurements. A factory calibration is performed against atmospheric fresh air before the monitor is shipped to you and an ongoing automatic calibration routine is enabled on each monitor.
Further calibration is therefore not required for most users.
The automatic self-calibration of the CO2 Monitor operates on continuous basis and assumes that the sensor is exposed to the background atmospheric CO2 concentration of 400ppm at least once per week.
If your CO2 monitor is installed in a location where it will not be exposed to fresh air at least once per week please Contact Us for further advice and assistance. This is not a recommended way of operating the CO2 monitor, but may be able to be supported for short-term scenarios depending on the specific situation.
Occasionally (e.g. after a significant drop/shock) it may be necessary to perform a forced re-calibration of the CO2 monitor to restore the measurement accuracy.
A forced re-calibration can only be initiated by co2mon.nz. If you have been asked to prepare for this, please follow these steps:
Once the above steps have been completed successfully the CO2 monitor is ready for the forced re-calibration to take place.
Please Contact Us before starting this process if you believe a forced recalibration is required for your CO2 monitor.
