The MT472 is a 690V AC/DC Voltage Tester and is a basic voltage tester designed to meet electrician’s requirements for the measurement of AC and DC voltage and continuity. The tester displays the voltage on red LED’s which increment as the voltage increases. There is an LED indication for polarity when DCV is measured. No switching of the meter on as the tester automatically turns on when voltage is applied to the two test probes. The MT472 incorporates a Low Impedance Test, which induces a basic load of approximately 6kΩ at 690 volts. The MT472 meets the CAT IV 600V and CAT III 1000V safety standards.
