  • RK9930 GROUND RESISTANCE TESTER

    Product introduction
    the AC grounding resistance tester is displayed on a 5-inch TFT LCD. The output current adopts hardware feedback and high-speed ARM MCU control technology to make the output current stable and reliable. The output current is driven by DDS + linear power amplifier. The output waveform is pure and the distortion is small. The tester is controlled by single-chip microcomputer, which makes its setting and operation very simple, and provides PLC remote control interface, RS232C, RS485, USB and other interfaces, which can facilitate users to quickly combine into a comprehensive test system.
     
     
    Application area

    The tester can be used to test the grounding resistance of household appliances, electronic instruments, electronic equipment, electric tools, electric heating appliances and other products.
     
    Performance characteristics
     
    1. The display parameters are eye-catching and intuitive. DDS digital signal synthesis technology is used to produce stable, pure and low distortion waveform
    2. Constant current output: the output current stability rate range is within 1%, to avoid the output current change due to input current voltage instability and load change.
    3. It has open circuit alarm function. The maximum test time is 999.9s.
    4. Four terminal method is used to eliminate the influence of contact resistance.
    5. The output frequency is 50 Hz / 60 Hz. It has alarm function of upper and lower limit of resistance.
    6. Chinese and English bilingual operation interface, to meet the needs of different users, support large capacity storage, adapt to different test application requirements
