Prevent  L and N phase reversed to cause the instrument chassis charged and the operator get an electric shock accident. Prevent abnormal grounding to ensure the ground return circuit unobstructed.  Prevent the operator from getting an electric shock, safeguard the personal safety.

                                  

Grounding failure fast cutting function

                          

Independent high voltage output warning function

When there is high voltage output or residual voltage in the high voltage side , lights will be flashing, reminding the operators  high voltage output.

Fast discharge function

After Dc withstand voltage and insulation resistance test is completed, With fast discharge (better than the 0.2 s),  cut off output function ,test at a faster rate, and can effectively protect the security of the operator  and test pieces

Fast shut off function

When test stops, the tester can shut off high voltage in 0.4 ms  , protecting  safety of operators.

Key-Lock Function

Prevent the operator modify the test parameters, guarantee the test pieces for testing in accordance with set parameters .

Open circuit short circuit detection function

In the process of test , determine whether a return  circuit is connectted in good condition, if open circuit, short circuit phenomenon, tester  alarm  sound and light

Pure hardware feedback, automatic voltage regulator

The output voltage does't change due to the difference of external load . when testing ,tester automatically adjust output voltage to the set value, automatic feedback adjustment time is very short.

Pure source

Using the principle of DDS to produce pure standard sine wave. By the linear power amplifier drive high voltage output, output sine wave ,pure waveform,ldistortion degree small,better than 1% , to ensure that measured components  data is correct.

●Average value, true RMS and so on a variety of current detection ways

●Supporting documents and newly build, delete, jump of test steps,and other new shortcuts, convenient management of the test files

●Ac withstand voltage, current test minimum resolution of 1 v, 1 mu A .Dc withstand voltage ,current test the minimum resolution of 1 v , 0.1 mu A, insulation resistance testing , the minimum resolution of 0.01 MΩ, 1 v                        

                                 

●Support RS232/RS485、PLC、GPIB、USB、print port and so on  many kinds of communication interface

●With Float and Ground mode automatic switching function：Float and Ground mode ,each have each advantages ，customers can decide on their own test mode according to  needs .At the same time, the machine can automatically detect whether mode of port and tested pieces are consistent.

                          

●Support system run log , record instrument parameters of boot time, total running time, test times and so on, convenient for users understand the instruments operation information

●Real current test function: effectively distinguish  the reactive current and real current of the capacitive load , correctly reflect the insulation  quality of DUT

●OSC open circuit/short circuit detect function：effective filter circuit object under test or judgment circuit poor contact, avoid misjudgment in production line , or make the equipment damage, cause the unnecessary  risk costs.

●AUTO-GFI grounding effect detection function: the traditional high voltage tester only through sound and light alarm to remind the operator, but the new development of AUTO - GFI function, by judging and detecting patent circuit of abnormal leakage current through the human body to the ground, once the leakage current is larger than the body's safe range, immediately cut off the high voltage output, truly protect the operator safety.
