DESCRIPTION
A multifunction meter is a
digital
measuring instrument designed to
measure various electrical or physical quantities. The meter has a
plastic casing, liquid crystal display, and a range/measured quantity
switch. The casing has measurement jacks fi tted. The meter comes
with test leads terminated with plugs. The meter is sold without a
battery.
Before using the meter, read the instruction manual in its en-
tirety and keep it for later use.
CAUTION! This meter is not a measuring instrument within the
meaning of the Metrological 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 meas-
ured 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 .
Replacing the battery
The multimeter requires batteries, the number and type of which
are specifi ed in the technical specifi cations. It is recommended to
use alkaline batteries. To install a battery, open the instrument cas-
