726 Users Manual Simulating RTDs Connect the Calibrator to the instrument under test as shown in Figure 17. Proceed as follows to simulate an RTD: M 1. If necessary, press 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. 36

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.
