The MT935 is a motor and phase rotation tester that operates on battery power. It can be used on both 3-phase powered systems and unpowered 3-phase motors without any concerns about damaging the tester. When used on a 3-phase powered system, this instrument serves as a field indication meter, illuminating corresponding lamps to display all three phases. Additionally, an LED indicates the rotation direction, either clockwise or counterclockwise. In the case of a 3-phase motor, the MT935 allows for the identification of motor connections U, V, and W without the presence of mains voltage, thereby preventing damage to pumps caused by reversed motor rotation. The MT935 operates efficiently on voltage ranges from 1V AC to 400V AC and is housed in a durable double-moulded rubber casing, making it ideal for heavy-duty usage.
