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 selector. The housing is equipped with measure-
ment sockets and a transistor test socket. The meter is equipped with measurement cables with plugs. The meter is sold without a
battery.
ATTENTION! The meter is not a measurement device as it is construed within the „Measurement Law”.

Remarks
Open circuit current approximately 0.25
V; Overload protection 250 V d.c./a.c.
The precision value does not include the er-
ror caused by the capacitance of the meter
and the measurement cables. For ranges
≤
400 nF it is necessary to deduct from the
result the capacitance of the meter and the
measurement cables
Range of the input signal voltage: 1 V rms ÷
20 V rms; use the automatic measurement
range selection
