Several well coordinated safety devices protect the instrument

against damage caused by incorrect operation and overloading

within the specified overload limit values:

• Oversized precision resistors

•

Fuse link in combination with protective rectifier diodes

Overvoltage arrester / positive temperature coefficient

resistors (PTCs)

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.

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.
