Verify mA Measure
1. Make the connections between the 712B, 8508A, and 5522A, as
shown in Figure 5.
2. Set the 8508A to DCI measurement mode, set the range of the DCI
measurement mode to 20 mA and the resolution of DCI measurement
mode to 7 1/2-digits.
3. Adjust the mA source output of 5522A and make that 8508A shows
as the first column in the Table 7, and verify that the 712B readings
are within the limits shown.
