4. OPERATION
4.1 PANEL DESCRIPTION
(refer to picture 1)
1)
①
Jaw: 0 to 1000 AC current and NCV
detecting device.
2)
②
Hand protection: A safe design to protect
users from touching the dangerous area.
3)
③
Clamp gunlock: Pressing the gunlock can turn on or off the
clamp.
4)
④
Clamp light
:
Opening the clamp light can light up the tested area
in the dark to prevent the danger.
5)
⑤
NCV indicator: Detect the existence of the high voltage around to
prevent the electric shock.
6)
⑥
Hold button: When pressing this button, the current measured
value will be kept on the LCD and cannot measure any new value at the
moment. Press this Hold button again to exit the hold mode.
7)
⑦
Function choosing switch: Used to select the function, range or
turn on or turn off the clamp meter.
