2. AC/DC measurement switch
3. DC Calibration
Before measuring DC current, press DCA ZERO key to
reduce the residual magnetism to Zero, and then
conduct measurement. Rational usage of this Adjust
Zero function will make the results more accurate. For
example, after boot, before measurement, we can take
the jaw close to the DC current wire. LCD will show an
inductive current. Press DCA ZERO to calibrate, which
deduct the inductive value, Showing below:

4. Current Measurement
Dangerous! Please don't use it to measure current
higher than 600A; otherwise there would be risk of
electric shock to cause personal injuries or equipment
damages
!
High voltage, extremely dangerous! Operators shall
strictly keep to safety rules; otherwise there would be
risk of electric shock to cause personal injuries or
casualties.
The tester default to DC measurement after boot up.
Press ~/
Ì
to switch the AC/DC function. LCD will
display DC or AC to corresponding switch function.
4) Read LCD display data. In case
OL mA
symbol was
displayed, it means that current of measured line is
beyond the maximum limit of this meter.
1) Power on.
2) Press ~/
Ì
to DC or AC measurement.
Conduct Adjust Zero before measure DC current.
3) Release the clamp lever to open input clamp and clamp
measured conductors. Be attention that the clamp must
be totally closed and the measuring wire passing
through the center of the jaw.
