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

), 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.
