Input the lowest temperature of the range which corresponds to the lowest voltage or
current value of the range to be scaled.
Example: range 0...120°C should correspond to 0...10 V approx.
Input 0, 0, 0, 0, 0

If the current input is selected, the programme asks whether 0...20 mA or 4...20 mA is
required.

Here the decision is made whether an automatic calibration procedure is started, or
whether the voltage or current values from the last calibration procedure are retained
with input 0 .
The display returns to the standard display.
With a new calibration the voltage or current source (e.g. setpoint unit, programmer)
must be connected up. The range limits must be adjustable.
