In situ alignment
During the in situ alignment the sensor does not necessarily have to be taken out of the control circuit.
We offer humidity standards for alignment of the sensors (page 3: accessories).
Before calibrating the sensor, standards should remain at least 2 hours on the sensors.
The temperature must remain constant during this time. For the correct temperature according to the humidity standard used,
please refer to data sheet F5.2 Humidity Standards.
During calibration temperature and humidity must remain constant.
During calibration, especially during storage of data, uninterrupted power supply of the sensor must be provided.
During calibration the following measurement ranges are shown on the display/ are used for calibration:
CH 1:
all sensors
CH 2:
sensors
with relative humidity RH output (CH1)
and temperature °C output (CH2)
sensors
with other hx-values outputs
The accuracies shown in the technical data of this data sheet refer exclusively to works calibration.
