The MT478 is a 2-pole voltage, continuity, and phase tester featuring fast LED indication of voltage levels

• A backlit LCD display provides accurate voltage readings for the user
• It measures voltage from 12V to 1000V AC/DC with LED indication and from 6V to 1000V AC/DC via the LCD display
• When voltage is detected, the tester provides visual (LED and LCD), audible, and vibration feedback when the load buttons are pressed
• The vibration function mimics traditional solenoid-type voltage testers and the unit complies with IEC1010-1 CAT IV 600V safety standards
• The MT478 also includes rotary field detection for 3-phase systems and a single-pole phase test
• Additional features include a built-in flashlight, continuity buzzer, and diode testing
• Constructed with a high-quality, heavy-duty molded case, it features a thicker cord with wear indicator and a robust, well-fitted probe protector
