DC current gain verification test
1 Connect the calibrator to the front panel I (red) and LO (black) input terminals
(see Figure 1-6, “Test setup for DC current and AC current gain verification,”
on page 31).
2 Press [] to select the DC current function. The DC annunciator will turn on
according to your selection.
3 Select each range in the order shown below. Provide the indicated input
current. Compare the measurement results to the appropriate test limits in
Table 1-4 (be certain to allow for appropriate source settling when using the
Fluke 5520A).
Table 1-3 DC voltage gain verification test
Input voltage Range Error from nominal 1-year
19.0000 mV 19.9999 mV ±0.0127 mV
100.000 mV 100.000 mV ±0.033 mV
1.00000 V 1.00000 V ±0.0003 V
10.0000 V 10.0000 V ±0.003 V
100.000 V 100.000 V ±0.03 V
1000.00 V 1000.00 V ±0.3 V
Set the calibrator output to 0 V before disconnecting from the instrument
input terminals.
