    888 PMR   Phase & Motor Rotation Testers
    888 PMR
    FEATURES
     
     Indicates Phase Presence.
     Indicates Phase Rotation.
     Indicates Motor Rotation/Wiring.
     Indicates Battery Status.
     Phase Rotation and Motor Rotation Indication works from as low as 1 Vac.
     Small and rugged enclosure.
     Color-coded test leads.
     Phase Presence Indication from as low as 1Vac.
     Very Low Consumption.
     Fused.
     Lighweight, Robust & Compact.
     Works from 2 Hz to 400 Hz Sine.
      CAT III 600V.
     Before connecting supply to load, you may do the following:
     On the supply side: Quickly verify the presence of the three Phases on a 3 Phases Power System. Confirm the Phase Rotation on a Powered 3 Phase System.
     On the Motor Side (Load): Confirm the Phase Rotation on a unpowered 3 Phase Motor 3 Phases Alternator. Confirm that each winding is connected to the terminals of the motor when the rotation Leds light up.
     The 888 PMR is a 3 phase Presence and Rotation Indicator combined with a 3 Phase Motor Rotation Tester.
     It can be utilized on a 3 Phase Powered System (the supply side) or on a Three Phase Unpowered Motor (the load side) without having to worry about damage to the tester.
     When utilized on a 3 Phase Powered System, the instrument is then utilized as a 3 Phase Presence and Rotation Indicator.
     When utilized on a Three Phase Unpowered Motor, the instrument is then utilized as a 3 Phase Motor Rotation Ttester.
     When utilized on a 3 Phase Powered System, this instrument is a rotary field indicatiOn instrument which display all three phases by lighting up its corresponding lamp. It displays the rotation (clockwise or counter-clockwise) on a LED.
     When utilized on a 3 Phase Unpowered Motor, it is also possible to determine the motor connections U, V, W without a live circuit to avoid subsequent damages of e.g. pumps to reversed motor rotation. It displays the rotation (clockwise or counter-clockwise) on a LED.
     This instrument represents the quickest and easiest way for servicing, repairing and electrical maintenance of 3 phase systems and 3 phase rotating machinery.
