The Sanwa MG1000 is a 3 range ( 1000V/500V/250V) digital insulation tester that features hot-line state detection, a large backlit display with bar graph and a tough, built-in carry case.

The MG1000 is a digital DC insulation resistance tester to measure the insulation resistance of power lines and equipment within 600V under CAT III. It has an insulation/resistance measurement range of 4M/40M/400M/4000MΩ, and a test voltage measurement range of 1000V/500V/250V. It has a large, 4200 count  display with a backlight and log bar graph - just like in an analog meter. The MG1000 also features a lock-down cover that functions as a dust-proof and splash-proof IP54 rated carry case.

This device can also measure AC and DC voltages with an accuracy of 3%, and a maximum voltage of 600 Volts (AC & DC). The AC frequency bandwidth range is 45 to 400 Hertz. An indicator LED lights up when the input is greater than or equal to 30 volts (AC/DC), and the buzzer turns on when the voltage exceeds 600 volts, the maximum voltage that can be displayed in 780 Volts.

Meter includes test leads, strap and instruction manual.
