Applications
The multimeter is equipped with an indicator display and an
electronic amplifier. It can be used in a wide variety of practical
electronics applications, for example in R&D, manufacturing,
equipment operation, in the test lab and for service calls, as well
as for training and vocational education.
Description
The multimeter has 46 measuring ranges for direct and
alternating voltages of up to 600 V, alternating voltage levels from
-40 to +62 dB, direct and alternating current of up to 10 A and
resistances of up to 20 MΩ. It has a constant input resistance of
10 MΩ in all voltage measuring ranges.
The multimeter is calibrated in RMS values for periodic sinusoidal
quantities. It makes use of full-wave rectification for the evaluation
of the arithmetic mean value.
All measuring ranges can be selected with the central measuring
range selector switch. The ranges are laid out in a clear-cut
fashion around the selector switch.
The measuring device and the display unit are enclosed in two
separate housing components which are connected to each
other by means of a hinge which can be snapped into various
positions. In this way, the ideal angle for ease of reading can be
selected with the instrument in any position.

The instrument can be operated independent of mains current
with a commercially available 9 V flat cell battery. Long battery
service life is assured thanks to the minimal current consumption
of the instrument’s electronic components.
The multimeter’s rugged design provides for outstanding
protection where harsh mechanical stressing prevails. When
folded together, the instrument is provided with extra mechanical
protection for the measuring device, as well as for the display unit.
The connector jacks are protected against accidental contact.
Suitable measurement cables with 4 mm test probes are included
as standard equipment.
