TO SIMULATE A THERMOCOUPLE
Work through the thermocouple
menu and make the selections as
required. Select the DIRECT mode
to simulate any temperature within
the range of the chosen
thermocouple type. Adjustment
resolution is 0.1 degree. For Cold
Junction compensation
considerations and different wiring methods read section "To simulate
thermocouples" in this book.
TO SIMULATE A RTD
The excitation current to source a resistance should be between 0.18
and 5 mA. Excitation currents may be intermittent as with some
smart temperature transmitters.
RTD Simulation
Go through the RTD menu and make the selections as required.
Select DIRECT mode to simulate any temperature within the range of
the chosen RTD type. Adjustment resolution is 0.1 or 0.01 degree
depending on RTD type. See the chapter “SPECIFICATIONS -
TRX-II” for details.
Resistances representing temperatures are really simulated across
the two terminals as shown. Connecting a third or a fourth wire
adapts the simulation to 3 or 4 wire inputs.
