UM4.6:CS6003 Original — December 1991
Step 7: Set the calibrator CHANNEL SELECT switch to channel 1.
Step 8: Using the terminal assignment list in Table 4-6, jumper
between the channel 1 negative and input common breakout
terminals. Connect the decade resistor between the positive
and negative input terminals for channel 1 on the RTD
termination panel. For accurate calibration, keep all test lead
connections tight.

Step 9: Use the label on the card to identify the card temperature
coefficient and, for the special temperature ranges, the
temperature range. Identify on Table 4-7, the correct set of
resistance values to use with your card. Set the decade
resistor to the resistance indicated for the 0.5 percent of span.
Adjust the ZERO potentiometer for channel 1 until the
calibrator numerical display is 0016.
