Installation and operating instructions
Room sensor KWL-VOC eC
4.4 Putting in operation
After switching on the device, a self-test and tempering period follows. This process
takes around 30 - 50 minutes, depending on the ambient conditions. Manual calibra-
tion can then be performed as an option. Make sure that no harmful substances
influence the calibration process and that the sensor is operated in fresh air.
4.5 Offset
The VOC measured value can be adjusted subsequently using the offset potentio-
meter. The adjusting range is ± 10 % of the measuring range.
