4. OPERATION
4.1 PANEL DESCRIPTION (refer to picture 1)
Jaw: 0 to 600 AC current and NCV detecting
device.
Clamp gunlock: Pressing the gunlock can turn on
or off the clamp.
Hand protection: A safe design to protect users
from touching the dangerous area.
Clamp light: Opening the clamp light can light up
the tested area in the dark to prevent the danger.
NCV indicator: Detect the existence of the high voltage around to
