3. MEASURING INSTRUCTION
3.1 DC Voltage Measurement
1) Connect the black test lead to "COM" socket and connect the red test lead
to the "VΩHz" socket.
2) Set the rotary switch to desired "V ”position and connect the probes
across the source or load under measurement.
3) Read the result from the LCD panel.

across the source or load under measurement.
3) Read the result from the LCD panel.
3.3 DC Current Measurement
1) Set the rotary switch to desired "200A “or "1000A " position.
2) Press the "REL", "0" will present on the screen.
Note:
As the jaw core may remain some magnetic force after using for a while. If the
display can not reach "0", please press the "REL” and take following process
to correct it:
A. To change the direction of the measured DC current.
B. Open the JAWS for several times.
3) Open the clamp by pressing the jaw-opening trigger and place the cable in
the middle of jaws.
4) Close the clamp jaws and get the reading from the LCD panel.
