Phase / Dead Motor Rotation Meter Technical Data MT935 The new MT935 is a compact handheld Motor and Phase Rotation indicator, which is battery operated. The unit can be utilized on a 3 Phase powered system or on a 3 Phase unpowered motor without having to worry about damage to the tester. When used on a 3 Phase powered system the meter is a field indication instrument which displays all three phases by lighting up its corresponding lamp. It then displays the rotation for clockwise or anti-clockwise on an LED. In 3 Phase motors it is possible to determine the motor connections U, V and W without mains voltage present, thus avoiding damage to pumps with reversed motor rotation. It operates from 1VAC to 400VAC. Features Include: Ordering Information • • • • • • • • LED Indication Rotary field direction 3-Phase neon Indication Determines Motor Connection and magnetic Field Detection Double injection rubber housing Small lightweight and portable Voltage range from 1VAC to 400VAC Large size crocodile clips General Specifications Operating Temperature Operating Altitude Pollution degree Type of Protection Size Weight Humidity Electrical Safety : : : : : : : : 0°C to +40°C 2000m 2 IP40 130(H) X 69(W) X 32(D) mm 130g 15% to 80% Meets DIN VDE 0411, IEC61010 DIN, VDE 04137 IEC 61557-7/EN 61557-7 Maximum Operating Voltage (Ume) Protection Levels Battery Current Consumption Battery Life : : : : : 400V AC for all ranges CAT III, 300V 9V Alkaline, IEC 6LR61 Max 20mA Minimum 1 year for average use Determine Rotary Field Direction Nominal Voltage Rotary Direction Nominal Voltage Phase Indirection Frequency Range (fn) Test Currents (in per phase) : 1 to 400V AC : 120 to 400V AC : Inspect the test leads for damaged insulation or exposed metal.
