ISOTEST M70 model is a innovative hand held Insulation tester\Meg Ohmmeter designed to perform insulation resistance measurements with test voltage up to 1000VDC and continuity test measurements of earth conductors with 200mA test current, in compliance to VDE 0100 requirements, on civil and industrial electrical environments. This meter can be useful also for test on electrical equipments and switchboards according to IEC/EN60204-1 and IEC/EN60439-1 standards. Thanks to LOCK feature, the insulation measurement can be performed in continuous mode on device under test. A programmable timer from 2s to 60s permits also duration measurements.Other features of meter are the DC/AC voltage measurement up to 600V, resistance and continuity test with buzzer as a common DMM. A very large and backlight custom display permits easy readings also in dark environments. Small sizes, ergonomic shape and a reduced weight (just 450g!) are ok conditions for any electrical installer.
