CS9950CX, CS9950D series programmable ground bond tester use micro-computer to control the output current and the frequency of output current ; That is to say, within the test range, the output current will not varies with the external load. The output current is set value; Besides, It is with the function of open-circuit alarm. Equipped with PLC interface and optional RS232 interface, it can be made up of the composition test system.  It can measure a variety of electrical motors, instruments, home appliances and the resistance between the accessible metal parts and the earth protection accurately.


• Constant current output

  Output current will not vary with the load and the mains supply, which guarantees that the accurate and reliable test.

• Linear power amplifier driver
  Using DDS principle to generate standard sine waveform, then linear power amplifier to driver. Its crest factor is within the range of 1.3 to 1.5
• Optional output frequency 
  Tester offers two output frequency 50Hz/60Hz; It is widely used in a vast region.
• Using four-terminal measuring method to test resistance, high precision
• Front panel software calibration
• Using 240x64 Graphic LCD display, user-friendly interface.
• Save pre-set parameters up to 30 files, each file can be set to 99 test steps
• Optional RS232, RS485 interface, standard PLC interface
