Simulating RTDs
Connect the Calibrator to the instrument under test as
shown in Figure 17. Proceed as follows to simulate an
RTD:
1. If necessary, press
M for SOURCE mode.
2. Press
R for the RTD display.
Note
Use the 3W and 4W terminals for measurement
only, not for simulation. The Calibrator simulates
a 2-wire RTD at its front panel. To connect to a
3-wire or 4-wire transmitter, use the stacking
cables to provide the extra wires. See Figure 17.
3. Enter the desired temperature by pressing X and
W. Press Y and Z to select a different digit to edit.
4. If the 726 display indicates ExI HI, the excitation
current from your device under test exceeds the
limits of the 726.
