2. Using the N to BNC cable, connect the CHAN 1 connector on the Calibrator
Mainframe to the Fluke 5520A Calibrator voltage binding posts using a BNC to
banana connector.
Record the 5820A reading for each voltage in Table 3-10.

Remove the front panel Current Loop using the 2 mm hex head driver.
3-34. DC Current Verification
1. Connect the DMM directly to the vacant banana jacks on the calibrator.
2. Program the Calibrator Mainframe to output the Currents listed in Table 3-11. Press
on the Calibrator Mainframe to activate the output.
3. Allow the HP 3458A reading to stabilize, then record the HP 3458A reading for each
current in Table 3-11.
4. Compare result to the tolerance column.
