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
2 wire
chosen RTD type. Adjustment
2 Leiter
resolution is 0.1 or 0.01 degree
2 fils
depending on RTD type.
See specifications for details.
Resistances representing
temperatures are simulated across the
two terminals as shown. Connecting a
third or a fourth wire adapts the
simulation to 3 or 4 wire inputs.

Excitation current

The excitation current to source a
resistance should be between 0.175
and 3.500 mA. Excitation currents may
be intermittent as with some smart
temperature transmitters.
