4.4.DCA MEASUREMENT
(I) Turn the rotary function switch to A
position.
The meter is default at DC A measurement after
power on. Press SELECT to switch
between AC or DC measurement.
(2) When the meter is used in a strong
magnetic field, the readings could
be unstahle or inaccurate. Press REL
to clear to zero before measurement.
(3)Press the clamp gunlock to open
the clamp jaw to get testing wire
inserted in the middle and clipped
completely.
To ensure measurement accuracy, please check to ensure that
the testing wire is placed in the middle of clamp jaw (fig.5).
Measure one wire in one time. If measure more than one wires
in one tirne, the reading will be inaccurate.
NOTE:
(1) The meter uses Hall component to detect current. Hall
component is a sensitive component. lt is magnetic sensitive.
It is also sensitive to temperature and mechanical stress.
Any impact on it would cause the changes on reading in a short time.
This causes some remaining values on the DC ampere reading
when there is no current. Toget accurate reading, press REL key
to clear reading before measurement, and the testing wire must
be placed in the middle of the clamp jaw.
(2) Press the clamp gunlock to open the clamp jaw to get testing
wire inserted in the middle and clipped completely. Ensure that
the testing wire is placed in the middle of clamp jaw. Otherwise
there will be additional accuracy ±l.0% of reading. Read the
measurement current value of the testing wire on the LCD.
(3 )In the measurement of the DC current, if the reading is
positive value, the current is top to down (broad is top, bottom
cover is down).
(4) The max.testing current is 600A. Exceeding the rated current
for long time will damage the meter.
Follow below instructions to get more accurate DC current
measurement:
1.) Switch off the testing wire.
2.) Press the clamp gunlock to open the clamp jaw to get testing
wire inserted in the middle and clipped completely. Ensure that
the testing wire is placed in the middle of clam pjaw.
3.) When the meter reading is stabilized in the minimum value,
press the REL key to clear it.
