meeting the test demand of photovoltaic system grounding resistance.


1, With 240 * 64 character LCD display, smart, intuitive display parameters.

2, Constant current output: the output current stability factor range within 1%, avoid the unstable input power supply voltage and load change and make the output voltage change, the measured results is not accurate.

3, With open alarm function.

4, Four-terminal method is used to measure and eliminate the influence of contact resistance.

5, Set up resistance deviation.

6, With resistance upper limit and lower limit alarm function, avoid make misjudgment to DUT due to the test line open circuit

7, Set parameters with functions of power losting memories.

8, Test parameters have keep function.

9,  Can be set in advance to save the test parameters, can set up to 30 files, each file can  set up 99 test step.

10, With the keyboard lock, protect the test parameters by the operating personnel changes.

11, The front panel calibration software, without opening the parameter calibration can be made.

12, The standard PLC interface, optional RS232C, RS485, USB, GPIB interface.


1, Safe electricity protection wall and safety protection system, can protect the safety of operator, ensure the tested pieces are not damaged.

2, Produced by DDS standard sine wave, linear power amplifier drive output, the output voltage waveform distortion degree, small pure, is better than 2%.

3, The output voltage is 40.0 Hz ~ 40.0 Hz frequency range, a resolution of 0.1 Hz;Can be used as a source of high voltage frequency conversion electric current;Industry is the only has a continuous adjustable frequency tester.

4.The test  results can be automatically stored in the tester, making it easy for users to check the test results; also can connect with the RS232 interface to lead the test results into EXCEL table to statistics and analysis.data

5, PLC interface test signal can  output 24 v level, can also  output contact.

6, With functions of list, when the test step is greater than 2, after the test, the tester can automatically show every step of the test results.
