Calibrating the zero point

Dry the sensor and keep it free from electromagnetic fields
If the zero point of the sensor is to be calibrated, it is essential that the sensor is
removed, rinsed and dried before calibration. No electromagnetic fields may influ‐
ence the sensor as these electromagnetic fields could distort calibration. Keep
devices that transmit radiation away from the sensor, such as mobile phones,
WLAN routers, sources of high voltage, transformers etc.
