Datasheet

Please do not loosen trigger suddenly. As a sensitive
device, Hall element will be sensitive to heat and
mechanical stress to different extents except 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.
