Features
- Pocket-sized, self-powered instrument – no battery maintenance problems
- Tests at 500 volts DC
- Powered by an easy-to-turn, low-voltage, AC brushless generator
The 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 M-ohm.
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 goodlegibility in most lighting conditions.An electronic circuit is used to give a four-decade resistance scale for insulation measurement.
