Calibration is performed for both the 150V range and the 300V range. The following
steps repeat for each range:
15.1.1 300V range calibration
1. Press Configure in the Setting and Measurement screen. Select 300V for the Range
(V).
Return to Setting and Measurement screen and select System → Next → Calibration and
enter the password 13579.
2. Select Vmeas (AC voltage) on the calibration menu.
Freq1, Freq2, Freq3 and Freq4 represent output frequency of 100Hz, 400Hz, 800Hz and
1200Hz respectively, and calibration is to be performed at each.
3. Press Freq1 key then press Cal. to start calibration. The instrument will output the
Low Point voltage.
Use the number keys to enter the voltage shown on the DMM, Press ENTER, then the
instrument will show “OK” after Low Point(V).
4. Press Cal. again to start calibration 2. The instrument will output ML Point voltage.
Use the number keys to enter the voltage shown on the DMM, Press ENTER and the
instrument will show “OK” after the ML Point(V).
5. Press Cal. again to start calibration 3. The instrument will output MH Point voltage.
Use the number keys to enter the voltage shown on the DMM, Press ENTER and the
instrument will show “OK” after the MH Point(V).
6. Press Cal. again to start calibration 4. The instrument will output High Point voltage.
Use the number keys to enter the voltage shown on the DMM, Press ENTER and the
instrument will show “OK” after the High Point(V).
