From the Calibration Menu, type the number or letter for Cal mV Input. The PC displays:
Enter 0 mV - press space bar to continue
Set the Fluke 5520A to output 0.000 mV, let the output settle then press the space bar on
the PC. After a short while, the PC displays the following calibration constant and new
prompt:
Offset = -714
Enter 90.00 mV - press space bar to continue
Set the Fluke 5520A to output 90.000 mV, let the output settle, then press the space bar
on the PC. After a short while, the PC displays the following calibration constants and
new prompt:
diff = (Counts - Offset)
7513104 = 7512390 - -714
mV per count = 0.000012
-press space bar to continue
Press the space bar to return to the Calibration Menu.
