1. Read “Testing Equipments” and “Testing Conditions”.
2. Press and enable AC voltage measure, and then separately set the range as
20kΩ and the reading resolution as “Slow”.
3. Press , and select T/C  PSW to input password and set SecrOff ,
then select Cal  Enter ;
4. Connect the voltage output of calibration instrument with HI-LO of the meter.
Then, set the output of calibration instrument as Sine, 100 mV, 1 KHz. Next,
enable the output and press Gain to start calibrating until it is stable. The results
will display in the table of UnCal G .
5. After finishing above steps, select Save to store the parameters have been
calibrated and exit.

Frequency Calibration
As for Frequency, only Gain is required to be calibrated, the procedures are:
1. Read “Testing Equipments” and “Testing Conditions”.
2. Press and enable frequency measure, then set the range as 2V, Manual.
3. Press , and select T/C  PSW to input password; then, set SecrOff and
select CAL  Enter .
4. Connect the voltage output of calibration instrument with HI-LO of the meter.
