Please do not loosen trigger suddenly. As a
sensitive device, Hall element will be sensitive to
heat and mechanical stress to different extents
in addition to magnetic sensitivity. Collision will
cause short-term reading variation. Please open
the clamp head by pressing trigger then fetch
measured conductor by clamp head and loosen
trigger slowly until it is closed completely. Please
check if measured conductor is in the middle of
clamp head or not. Additional error may be caused
if failing to place it in the middle of clamp head.
Clamp meter can measure a current conductor
once and measurement reading error may be
caused if measuring two or more current
conductors at the same time.

Note:
Current measurement function must be operated
between
0 and 40 . Current direction is
from bottom to top for positive reading during
DC current measurement. (As shown in Figure
11, panel is on the top and bottom cover is on the
bottom.) Please do not loosen the trigger
suddenly after pressing. As a sensitive device,
Hall element will be sensitive to heat and
mechanical stress to different extents addition to
magnetic sensitivity. Collision will cause short
-term reading variation.
More correct
by following operation methods:
Press the trigger and open clamp head to
fetch measured conductor by clamp head then
loosen trigger slowly until clamp head is closed
completely. Please check if measured conductor
is in the middle of clamp head or not. Additional
reading error of 1.0% may be caused if failing
to place it in the middle of clamp head;
