PROGRAMMING OF THE OHMIC VALUES OF THE TEMPERATURE AND PRESSURE TRANSMITTERS
(PROBES)
WARNING:
It is necessary to program at least 2 values (to obtain good precision in the control of temperature
and pressure, we recommend programming at least 4 values).
If just one value is programmed or non-monotone values are programmed, the fault is detected.

By factory default, the control unit is set for pressure and temperature transmitters TYPE TPO/403 (Pressure),
TTAO/403 (Temperature). It is possible to program 10 resistive values, corresponding to the characteristic curves of
other temperature and pressure transmitters.
