2. Press the Up
arrow button to scroll to the Internal calibration menu
(
ICAL) and press Enter.
3. The meter displays either current calibration (
C CAL) or voltage cali-
bration (
v CAL), according to the input setup. Press Enter to start
the calibration process.
Example of Internal Calibration for current input:
4. The meter displays low input current message (C lo). Apply the low
input signal and press Enter. The display flashes for a moment while
the meter is accepting the low input signal.
5. After the display stops flashing, a number is displayed with the left-
most digit brighter than the rest. The bright digit is the active digit
that can be changed by pressing the Up
arrow button. Press the
Right
arrow button to move to the next digit.
6. Set the display value to correspond to the input signal being cali-
brated, typically 4.000 mA.
7. The display moves to the
high input calibration (C Hi). Apply the
high input signal and press Enter.
8. Set the display for the high input calibration, in the same way as it
was set for the low input calibration, typically 20.000 mA.
