DESCRIPTION
A multifunction meter is a digital measuring instru-
ment 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 man-
ual in its entirety and keep it for later use.
CAUTION! This meter is not a measuring instrument
within the meaning of the Metrological Act.
