Application

This portable, battery-operated microohmmeter is a practical instrument for low resistance measurement in the fi eld. It is of rugged construction, contained in a sealed ABS plastic case with lid and carrying handle, ideal for use in the production and any other working fi eld or test and service facilities. The documentation of the measuring values is effected via RS232 interface directly to an external printer or PC. Further it is possible to perform single measurements via an external start switch.

Typical applications are measurements on:

1. Engine and transformer windings
2. Electrical connectors
3. Heating elements
4. Connections on power rails
5. Wires and cable drums
6. Quality of soldered and welded joints
7. Switching contacts

Description

Four-wire technology in accordance with KELVIN eliminates transition and lead resistance.

Any of the 8 measuring ranges can be selected by a key on the membrane keyboard. The measuring results are displayed on a 6000 counts LED display. The measuring terminals are protected up to 415 volts rms.

By forward and reserve current measurement with automatic average a thermocouple compensation can be realized which is inevitable for certain measurements.

The digital calibration of this instrument is activated by a key on the front panel.

The integrated rechargeable battery allows measurements up to 10 hours.
