The MT550 is an easy to use digital insulation and continuity tester in a single, compact handheld unit, which provides maximum versatility for both trouble-shooting and preventative maintenance. The MT550 offers three insulation test ranges: 250V, 500V and 1000V together with 200mA short current for continuity range and 200Ω and 200kΩ resistance range. The MT550 measures AC/DC voltage, battery voltage indication, a continuity buzzer, data hold function and LED back light.
