Example of Internal Calibration for 100 mV input range:
4. The meter displays the message “stroff” (strain offset), short the
SG+, SG- terminals and press Enter. The low input message is
displayed (v lo). Apply the low input signal (e.g. 0.00 mV) 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 0.00 mV.
7. The display moves to the high input calibration (v 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 100.00 mV.
The graphic above shows the calibration of the 100 mV input range. The
other input ranges are calibrated in a similar way.
Tips:
 Low and high input signals can be any valid values within the
range of the meter.
 Observe minimum input span requirements between input 1
and input 2.
 Low input should be less than high input signal.
