Combining three instruments in one, Megger’s unique handheld IMT100 multifunction tester qualifies solar PV (photovoltaic) installations. Installers and maintainers need only add a current clamp to their toolbox for complete IEC 62446-2 Category 1 coverage.

The instrument is exceptionally safe to use, with fast detecting circuits. It accurately tests low resistance, continuity and insulation resistance, measuring up to 200 GΩ with a resolution of 0.1 kΩ. Testing uses two-, three- and four-terminal methods.

Operation is intuitive with a clear full-colour graphic display. Simple go/no-go tests combine with extensive fault finding and reporting for certification and review.

The instrument meets IP54 and is rugged and reliable for rooftop operation. A carry case holds all the accessories for easy portability around large sites.

The IMT100 has rechargeable batteries and is user upgradeable via USB. It also meets the UN EEC R100 Regulation for Hybrid and Electric Vehicle testing.
