Product Detail

Portable Crcuit Breaker Tester Switch Characteristic Tester Features

  • Equipped with linear and rotary sensors, and a dedicated fixed multi-functional connector, installation is extremely convenient and simple. The linear sensor length can be set arbitrarily from 30-1000mm; only the sensor needs to be installed, and the instrument does not require factory program modification.
  • The main unit can store 100 sets of current test data, and has an internal real-time clock for easy archiving.
  • Equipped with a USB flash drive interface and an RS232 interface. Data can be saved to a USB flash drive and uploaded to a computer for analysis, storage, and printing. The RS232 interface allows for online computer connection (optional function).
  • The internal anti-interference circuitry ensures reliable operation within a 500kV substation.
