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.

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.
