The MI-1050e general purposes megohmmeter is a truly
portable equipment suitable to measure insulation resistances using
test voltages up to 1 kV. It employs high-reliable, state-of-the-art
technology for accurate measurements of ultra high insulation resistances
up to 2.000.000 MO with four test voltages: 100 V, 250 V, 500 V
and 1.000 V. Readings are performed through an easy-to-read analogue
indicator having a broad scale.
