Remarks:
If the current flow is from the back of the meter to the front, the reading will be
positive. The opposite direction will provide a negative reading. The internal
components are very sensitive to magnetic fields and physical force and shock.
It is important to hold the Meter firmly and steadily while taking measurements.
The following procedure will provide the most precise readings:
1. Turn off the current of tested conductor.
2. Hold the Meter tight and press the lever to open the transformer jaw. Center
the conductor within the transformer jaws, then release the Meter slowly until
the transformer jaw is completely closed. Make sure the conductor to be tested
is placed at the center of the transformer jaw, otherwise it will cause +1.0%
deviation based on the stated accuracy.
3. Press
ZERO
button
to
display zero.
4. Turn on the current of tested conductor reading the stable value of clamp
meter.
5. The obtained reading will be more precise.
