Verify Instrument Configuration with HART Communicator
This will help you to be sure to apply the correct input with which to trim your STZ. By example:
If the Sensor 1 Measure Mode is “RTD 4 wire” and the Sensor 1 Input Type is “Pt 3850 1000
ohm” and Sensor 1 EGU is “deg F” then you should be using an accurate resistance source
(such as a decade box) to emulate the 4-wire, Pt 3850, 1000Ω RTD and use the Fahrenheit
temperature tables to source the correct resistances for your specific temperature range. Be
sure to also check the HART Communicator’s Online Menu to see your instrument’s PV LRV
(Primary Variable Lower Range Value) and PV URV (Primary Variable Upper Range Value)
settings so that you know the span of temperature to be used.
Now you are ready to do the actual input trimming of your STZ. Using your HART
Communicator, follow Figure 2.4 below and steps on next page for clarity.
