DESCRIPTION
The universal clamp meter is a digital measuring instrument designed to measure various electrical quantities. In the
case of some measurement quantities, the meter can select the range depending on the measurement result. The
meter is fi tted with a measuring clamp allowing the measurement of AC current in a single wire using an inductive
method.
Before using the meter, read the instruction manual in its entirety and keep it for later use.
The meter has a plastic casing, liquid crystal display, and a measuring range switch. The casing has measurement
jacks fi tted. The meter comes with test leads terminated with plugs. The meter is sold without a battery.
CAUTION! This meter is not a measuring instrument within the meaning of the Trade Metrology Act.

OPERATION
CAUTION! To avoid the risk of electric shock, disconnect the test leads and switch off the meter before opening the casing.
Safety instructions
Do not operate the meter in an atmosphere with excessive humidity or in the presence of toxic or fl ammable vapours,
or in an explosive atmosphere. Before each use, check the condition of the meter and the test leads. If you notice
any faults, do not start its operation. Replace damaged cables with new ones, devoid of defects. In the case of any
doubts, you should contact the manufacturer. During measurement the test leads should be held by the insulated
parts. Do not touch the measurement points or unused measuring jacks of the meter. Disconnect the test leads before
changing the measured quantity. Never carry out maintenance work without ensuring that the test leads have been
disconnected from the meter and that the meter itself has been switched off .
