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
leftmost 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.

The graphic above shows the calibration of the current input. The vol-
tage input is calibrated in a similar way.
