3. MEASURING INSTRUCTION
3.1 DC Voltage measurement
1) Connect the black test lead to "COM" socket and red test lead to the "VΩ"
socket.
2) Set the selector switch to desired "mV " or "V " position and connect the
probes across the source or load under measurement.
3) Read the result from the LCD panel.
3.2 AC Voltage measurement
1) Connect the black test lead to "COM" socket and red test lead to the "VΩ"
socket.
2) Set the selector switch to desired "V ～ " position and connect the
probes across the source or load under measurement.
3) Read the result from the LCD panel.
3.3 DC Current Measurement
1) Set the selector switch to desired "200 “or "1000A " position.
2) Press the "REL" the display show "0".
Note:
As the jaw core may remain some magnetic force after using for a while. If the
display can not reach "0" When Press the "REL”, please take following
process to correct it:
A. To change the direction of the measured DC current.
B. Open the JAWS several times.
3) Open the clamp by pressing the jaw-opening handle and insert the cable to
be measured into the jaw.
4) Close the clamp and get the reading from the LCD panel.
Note:
Before this measurement, disconnect the test lead with the meter for safety.
Non unit sign display of DCA.
3.4 AC Current measurement
1) Set selector switch to desired "400/1000A～" position.
2) Open the clamp by pressing the jaw-opening handle and insert the cable
( one cable only) to be measured into the jaw.
3) Close the clamp and get the reading from the LCD panel.
