The MT476 is IP64 and is a useful voltage tester designed to meet the Electrician’s requirements for a multitude of applications. This tester enables the user to determine whether or not a voltage is within the range required. The MT476 voltage tester incorporates a Low Impedance Test, which induces a basic load of approximately 2.1W at 690 volts. The MT476 meets the International Safety Standard IEC61010-1 CAT III 1000V and CATIV 600V. This voltage tester operates without a switch, and by simply placing the probes of the MT476 onto the circuit under test, the meter is automatically turned on and can measure the voltage, continuity or polarity test. This safety design ensures that if the user incorrectly handles the meter, danger is eliminated.
