Adjustment Procedure
1.
Connect all test equipment except the calibrator, as shown in Figure 3.
2.
Call

.
Note
Do not call
RM-26999 Close External Calibration.vi
before
completing all adjustment steps. Closing the session early will invalidate
all adjustments and measurements.
3.
Call
RM-26999 Configure DC Calibration Stimulus.vi
.
a.
Use the high voltage values from Table 3 as input for the VI.
Repeat 2 times, once for each polarity.
Repeat 4 times, once for each channel.
4.
Power off the calibrator output.
Caution: Possibility of Electric Shock
Power off all high-voltage signals before making any connections.
5.
Connect the calibrator output to channel 1 on the DUT.
Repeat 4 times, once for each set of voltage values.
