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.
