Description Features: 1. Using clamp-type non-contact inductive measurement, the phase sequence can be detected by directly clamping the three super-induction high-insulation clamps on the insulation sheath of the three-phase heat wire respectively. 2.There are four powerful magnets on the back of the meter, which can be used by hanging on the power distribution box. 3.At the same time, it has functions such as live line inspection, simple power detection, open circuit search, break point positioning, and line maintenance. 4.Quick and convenient detection, clear display, greatly improving the safety of field testing, 5. The personal safety of the operator is effectively protected, and it is a safety instrument for three-phase power phase sequence, motor detection, and line maintenance Specification: Function: Phase detection (normal phase, reverse phase, lack of phase), live line inspection, simple power detection, breakpoint positioning, line maintenance Power source: DC3V 2x 5th battery (excluding battery), Continuous use time: about 70 hours Active power range: AC 70-1000V, 45 65Hz (sine wave continuous input) Clamping wire size: outer diameter 1.6mm-16mm or 10mm 40mm (optional) LED display: Normal phase: 4 phase detection lights turn on in a clockwise direction; Reverse phase: 4 phase detection lights turn on counterclockwise sequentially; Live power: Light1, L2, L3 lights are on within the voltage setting range; Phase loss: Light1 or L2 or L3 lights are not on; Open circuit: Light1 or L2 or L3 lights are not on. Beep: Normal phase: the instrument emits intermittent short beeps; Reverse phase: the instrument emits continuous long beeps. Battery check: Power indicator light is on after power on; LOW BATTERY light is on when battery is low Magnetic force: Four magnets are attached to the back of the meter, which can be hung on the power distribution box and can bear a weight of 800g Automatic shutdown: the instrument will automatically shut down after about 5 minutes Instrument size: 70 75 30mm Clamp lead length: 0.6m Working temperature and humidity: -10-55 degrees Celsius; below 80% rh Storage temperature and humidity: -20-60 degrees Celsius; below 90% rh Measure the highest voltage: AC 1000V Insulation strength: 5.4kVrms Maximum rated power: 300mVA Package Includes: 1x Phase Meter 1x manualincludes:1x Phase Meter 1x manual
