This procedure tells you how to use the indicator to adjust the probe's measurement in 1 ... 2
points.
1. Connect the probe(s) to the indicator.
2. Open the main menu by pressing
3. Select Devices. If you have more than one device connected to the indicator, make a
further selection between the devices.

start the purge manually by selecting Devices > <your device> > Sensor purge.
After the purge has been completed, continue to the next step.

6. Select the parameter, for example, Relative humidity.

the stabilizing graph view. Wait for the measurement to stabilize fully.

the automatically filled Measured value, point 1 and Measured temperature,
point 1 with your actual values.

reference point. Then scroll down the <parameter> adjustment view and select
