DESCRIPTION
A multifunction meter is a digital measuring instrument designed to measure var-
ious 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 entirety 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, de-
void 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. Dis-
connect the test leads before changing the measured quantity. Never carry out
