PROJECT: Megohmmeter Insulation Resistance Tester

Megohmmeter Insulation Resistance Tester

Other names: Digit Megohmmeter

                    Insulation Resistance Tester

                    Digit Megohmmeter

Measuring range: 0~19990MΩ

Resolution: 0.01MΩ,0.1MΩ,1.0MΩ,10.0MΩ

DC: 8×1.5V(AA,R6) battery

AC: 220V/50Hz

Description:

Digit Megohmmeter consists of medium and large scale integrated circuit with high output power and high short-circuit current value features. The output voltage is up to four grades. The built-in battery served as power supply become high DC voltage by DC/DC transformation, which goes from E pole to L pole via the object being tested. By this way, it produces a current from pole E to pole L, which converted by I/V and computed by the divider. The value of insulation resistance will display on the LCD finally.
