DC Current Verification Test
1 Connect the calibrator to the front panel Hi and Lo input connectors.
2 Select each function and range in the order shown in Table 4- 3. Provide the
input shown in Table 4- 3.
3 Make a measurement and observe the result. Compare measurement results
to the appropriate test limits shown in Table 4- 3. (Be certain to allow for
appropriate source settling when using the Fluke 5520A.)
