 Description Click here to view full-pdf specification sheets Pocket-sized, self-powered instrument - no battery maintenance problems Tests at 500 volts d.c. Powered by an easy-to-turn, low-voltage, ac brushless generator The Wee MEGGER WM6 tester is a self-contained instrument designed to give rapid and accurate resistance measurements. The hand-operated generator is coupled with the latest electronic technology, thus allowing the WM6 to test insulation at 500 V d.c. up to 200 MW. A low-voltage, hand-cranked, a.c. brushless generator, which is easy to turn by hand, is the power source. It is connected to a stabilized electronic invertor to provide the test voltage. All resistance readings are given directly on a moving-coil meter with a rugged taut-band suspension movement, a white-on-black scale and an orange "dayglow" pointer. This gives good legibility in most lighting conditions. An electronic circuit is used to give a four-decade resistance scale for insulation measurement. Applications The WM6 tester is suitable for the direct measurement of insulation resistance and continuity of domestic and industrial wiring, cables, trans-formers, motors, generators, electrical machinery and appliances. It is suitable for use during installation and commissioning work as well as servicing and maintenance applications. The WM6 may be used to measure the insulation resistance of 415/240-V a.c. wiring installations to prove that they comply with wiring regulations.
