Product Description
1. Instrument working principle
RS2671 digital megohm meter consists of mid and large-scaled integrated circuits. The instrument has large output power, high short circuit current value and multiple output voltage levels (four voltage levels). Working principle: the built-in battery, as the power supply, generate DC high voltage through DC/DC conversion, which reaches Pole L from Pole E through test object, thus generating current from E to L; the current passes through I/V conversion and measured insulation resistance value is directly displayed on LCD after divider completes calculation.
2. Instrument application range
The instrument is a frequently-used and essential instrument for electric power, post and telecommunication, communication, mechanical and electrical installation, maintenance and industrial enterprises and departments using power as industrial power or energy. It is applicable to measure the resistance of various insulating material, and insulation resistance of power transformer, motor, cable, electric equipment, etc.
