Caractéristiques

• Safe to use - For ground fault tracing, the device uses as low current as microamperes measurement signal and DC current clamp with high resolution, and it has no interference to the tested systems
• High reliable designing - It adopts the main system of the 32-bit microprocessor. Hardware designing strictly follows EMC standard to ensure the reliability of itself and its tested systems
• Precise measurement - It adopts a highly accurate current clamp for signal tracing and precise ADC for voltage sampling to ensure accurate measurement of voltage and resistance
• User-friendly interface - It has an LCD display with vivid information indicating grounding status, waveform, insulation leveling, insulation resistance, leakage current, and direction of a ground fault, and so on. This user-friendly interface makes it easy and effective to use onsite
• Intelligent measurement function
  • Signal analyzer can automatically identify system voltage leveling
  • When insulation resistance has any change, signal analyzer could quickly indicate the changes
  • Distance will not affect the signal detection once the signal analyzer and detector are synchronized
  • During fault location, the current clamp could either clamp-on single cable or multiple cables for faster and more effective signal tracing
  • Signal detector will indicate the direction of a ground fault on the screen once it detects any insulation problem
  • Complete measurement and trouble-shooting function
  • Signal detector and analyzer have wireless communication. Complete measurement and info displaying function could handle different types of insulation problem in the DC system
  • Signal analyzer has different working modes like amplitude adjustment and waveform view, which are suitable for different complicated applications
