The MI-2550e general purposes megohmmeter is a truly
portable equipment suitable to measure insulation resistances using
test voltages up to 2,5 kV. It employs high-reliable, state-of-the-art
technology for accurate measurements of ultra high insulation resistances
up to 5.000.000 MO with four test voltages: 0,5 kV - 1 kV - 1,5
kV - 2,5 kV. Readings are performed through an easy-to-read analogue
indicator having a broad scale.
