8. Configuration
SCH2 = 80:
20 mA corresponds to a measured value of 80 °C, as already described
Value range: -1999...+9999 digit
Factory setting: 100 digit
The controller restricts the setpoints to the set value.
Value range: -1999...+9999 digit
Factory setting: 0 digit
The controller restricts the setpoints to the set value.
Value range: -1999...+9999 digit
Factory setting: 100 digit
The actual value correction can be used for correction of the measured value upwards
or downwards by a specific amount. It is also used for line compensation when
resistance thermometers are connected in a 2-wire circuit.
Value range: -1999...+9999 digit
Factory setting: 0 digit
