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.
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"
