The

Internal calibration menu is part of the Advanced Features menu.

1. Press and hold the Menu button for three seconds to access the

advanced features of the meter.

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

calibration (

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

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

calibrated, 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 voltage

input is calibrated in a similar way.
