- Four test voltages to 5 kV
- Dual power supply option giving the best of both worlds
- Resilient mounted analogue scale for robustness
- Voltage range to 600 V indicates auto discharge
- Pass/fail overlays for rapid testing
- Single scale for insulation values to avoid operator error
The Megger® BM15 & MJ15 are compact 5 kV insulation testers. They are very simple to use and provide a quick and accurate reading of insulation resistance. The instruments use an analogue display with a maximum reading of 20 GΩ. The BM15 is powered by batteries. The MJ15 has an additional hand-cranked generator.
The instrument operation is extremely simple. A voltage range enables measurement of a.c. or d.c. conductor potential. Four test voltages are available at 500 V, 1 kV, 2,5 kV and 5 kV. A choice of push buttons is supplied; a locking button simplifies long term testing, or a nonlocking version is preferred for maximum safety.
