10.14.1 Trimming the RTDs
1
Change the Home Screen on the transmitter to read the temperature of the RTDs
2
Connect a computer with SoloCUE Flow Device Manager software to the UTM20 transmitter In
the Setup > Input tab, check the Temp Sensor Type and Range
3
With a constant temperature controlled heat source at the midpoint of the operating range, heat
RTD 1 Allow time for the RTD to heat thoroughly
4
Compare the temperature of the heat source with the temperature reading of Temp 1 on the
display In SoloCUE, adjust the Trim RTD 1 until Temp 1 matches the heat source temperature
5
Repeat steps #3 and #4 for RTD 2
