Recording of analog measured values

Note
For the recording of analog measured values a PM4000 U/I Temperature must be available.
No links of any kind to the functionality of the heating control are available.
Analog inputs 0...20 mA
Four inputs are available for recording of measured current values for a current measuring
range of 0...20 mA.
The measured current values can, for example, be used with a pyrometer for temperature
measurement.
If values are measured outside the measuring range, an error message is generated and an
invalid measured value (-32767) is displayed.
Temperature measuring inputs
Four measuring inputs are available for recording measured temperature values. Measured
values for Pt 100 and Pt 1000 can be recorded, as well as for thermocouples of types J, K
and L.
If values are measured outside the measuring range, an error message is generated and an
invalid measured value (-32767) is displayed.
Compensation procedure
Various compensation procedures are available for recording measured values of
thermocouples:
● Internal compensation: In this procedure, the temperature is recorded at the terminal and
included in the calculation of the temperature of the thermocouple.
● External compensation: In this procedure, the user can transmit the compensation value
for the temperature calculation of a thermocouple which is recorded, for example, by
means of a Pt 100 outside the HCS.
