Problems related to temperature transmitter

When we are measuring temperature from Honeywell STT 850 Temperature Transmitter…Pv unit is showing in mv. And now when we are trying to connect with Hart communicator and changing Pv unit to degree celcius, it is showing invalid selection .How can we change units to Degrees for the Transmitter



device setup

display setup

screen confirmation


so configure again here change the unit

You have to change the unit, not the PV, just change the unit whatever you want, will find PV in the same unit.
