AC current ranges calibration
a)
Select Current AC#1 from the calibration menu and confirm by pressing Select
softkey. Set the same function on external multimeter.
b)
Follow the instructions provided on the calibrator’s display and the ACI table to
adjust the calibrator’s output in the calibration points.
c)

,
cursor buttons, rotary knob or numeric keyboard to adjust the output
voltage. Confirm correctly set value by pressing Write softkey. If you want to skip
the calibration point whose calibration you have already entered, press Exit softkey.
d)
Resistance shunt should be used on 2, 5, 10 and 30 A ranges, if standard multimeter
does not cover this range.
e)
Repeat steps a) to d) also for Current AC#2 and Current AC#3.
6.
DC voltage ranges calibration
a)
Select Voltage DC#1 from the calibration menu and confirm by pressing Select
softkey. Switch calibrator’s output terminals ON.
b)
Follow the instructions provided on the calibrator’s display and the DCU table to
