1.3 Calibration
The device uses automatic CO2 measurement calibration function (ABC algorithm). The function
eliminates the possible long term drift. The automatic calibration function can be used when the CO2
concentration drops at least two times within a week to the level of approximately 400 ppm. Therefore
the automatic calibration is effective in spaces that are not continuously occupied.
The automatic calibration function can be deactivated in continuously occupied spaces by using ML-SER
tool.

Published: 28.08.2019 4 (15)
If the automatic calibration function is not in use, the device should be calibrated every 6-12 months.
The recommended calibration interval is 5 years even if the automatic calibration is in use.
1.4 ML-SER tool
1.4.1 Connecting ML-SER tool to the device
1. Open the cover.
2. Disconnect the display cable.
3. Connect the ML-SER cable to the display connector.

1.4.2 ML-SER menu
ML-SER menu opens by pressing the M button. The values can be changed with the ”+” and ”-”
buttons. The menu is device-specific and the content depends on the device and installed options.
The following menu structure contains the factory settings.
Note: The default relay CO2 set point is 2500 ppm in 10K models.
