• 4 x AA batteries, soft carry case and instruction manual. PSI4000 Phase Rotation Indicator. The Martindale PSI4000 is a unique phase rotation indicator that carries out the measurement via inductive crocodile clips. This method increases the safety of the ***r, whilst the bright LEDs give a clear indication of either clockwise or anti-clockwise phase rotation. The design of this phase rotation tester allows for *** on both insulated or uninsulated conductors, and an "Enhanced Brightness" switch makes indication brighter in strong ambient light. A combination of both rotating LEDs and buzzer tones indicate clockwise or anti-clockwise rotation. Input Voltage: 150V-1000V 3-Phase AC. Frequency Range: 45-65Hz Operating Temperature & Humidity: -10 °C to 50 °C, Max. 80%RH. Battery Current consumption: 15mA Cable Length: Approx. 800 mm Power Source: 1.5V X 4 (AA or LR6) alkaline batteries Auto-Off: After 5 mins of non activity Low Battery Warning: Power LED flashes below 4.6V DC battery voltage
