Step 6: Press the calibrator AO group mode switch.
Step 7: Set the calibrator CHANNEL SELECT switch to channel 1.
Step 8: If the card is a voltage output version, connect the voltmeter
between the calibrator breakout terminals listed in Table 4-19
for channel 1. If the card is a current output card, connect the
voltmeter across the calibrator 250 OHM LOAD terminals and
jumper the calibrator breakout terminals for channel 1 to the
calibrator 250 OHM LOAD terminals.

Note
Verify analog output card type before calibration.
The voltage output card cannot drive a 250 ohm
load. A current output card will produce very high
readings if it is not loaded.
