            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.
