Product description

Product Introduction
  Used for phase verification and phase sequence verification of high-voltage power lines and substations, it has reliable high-voltage electrical safety isolation performance. It adopts wireless transmission technology to ensure the personal safety of testers, and the audio-visual prompts are intuitive and clear, making it particularly suitable for on-site use.
 
Main Features
  ◆ Chinese character display of in-phase or out-of-phase, leading or lagging, and audio prompts;
  ◆ Digital display of phase angle 1°~360°, and intuitive phasor diagram display;
  ◆ Can display the voltage waveforms collected by X and Y, facilitating operator analysis and preventing misjudgment;
  ◆ Can display the amplitude ratio, used to analyze the voltage ratio;
  ◆ Has an automatic correction function, which can correct the phase and amplitude errors of the sampling;
  ◆ The host and slave units are powered by rechargeable lithium batteries.
