OPERATING MANUAL
PROPERTIES OF THE DEVICE
The all-purpose meter is a digital measurement instrument designed to measure distinct electrical quantities. In case of certain meas-
urement quantities the meter adapts an adequate range depending on the result of the measurement. The meter is equipped with
measurement pincers, which permit to measure the intensity of alternating current in a single conductor with the inductive method.
Before using the meter, read the whole manual and keep it.
The meter has a plastic housing, a liquid crystal display and a measurement range switch. The housing is equipped with measurement
sockets and a transistor check socket. The meter is equipped with measurement cables with plugs. The meter is supplied without a
battery.
ATTENTION! The meter is not a measurement device as it is construed within the „Measurement Law”

OPERATION OF THE MULTIMETER
ATTENTION! In order to protect from electric shock before the housing of the device is opened, disconnect the measurement cables
and turn the meter off.
Safety instructions
Do not operate the meter in the presence of an excessive humidity, toxic or inflammable vapours and in explosive atmosphere. Before
