From the Calibration Menu, type the cal step for Cal Volts Input. The PC displays:
Enter 0 Volts - press “ the proper key” to continue
Set the Fluke 5520A to output 0.0000 V, then press the space bar. After a short while, the
following calibration constant and prompt are displayed on the PC:
Offset = -40
Enter 10.00 Volts - press space bar to continue
Set the Fluke 5520A to output 10.0000 V, and press the space bar. After a short while,
the following calibration constants and prompt are displayed on the PC:
diff = (Counts - Offset)
3032676 = 3032636 - -40
Volts per count = 0.000003
- press space bar to continue
Press the space bar to return to the Calibration Menu.
