Battery indicator

This LED is unlit when the switch is OFF.

In normal use, the green LED is lit. When the switch is no longer in the OFF position and the

LED is unlit, this warns that the value of the battery voltage is too low or that the cell is no longer

supplied with power, thus showing that there is a fault in the clamp.

Resetting zero on the clamp

The thumbwheel makes it possible to reset the output voltage to zero. It is thus possible to

overcome the different errors due to thermal shifts, the Earth’s magnetic field, the environment,

and residual induction.

Indicator of range overload

This indicator symbolised by «OL» shows as a red light when the measurement signal is

outside the capabilities of the range. It can also indicate the presence of an impulse outside

the capabilities of the range or that the measurement made on the clamp isn’t valid.

Battery compartment

To change the 9V battery, the clamp should be in the normal position (jaws closed) and

disconnected from the oscilloscope, it must not clamp any conductor and the switch must be

in the «OFF» position. Unscrew the tool release screw then pull off the cover in the handle

extension to access the battery to be changed.
