Safety protection performance of DC high voltage generator


Over-current protection: When the high-voltage output terminal is short-circuited, the instrument should immediately cut off the output; at the same time, the instrument should not be damaged. There is over-current protection, and there are Chinese alarm prompts and sound prompts.


Overvoltage protection: When the high voltage output exceeds the overvoltage setting value, the instrument should automatically cut off the output immediately. This ensures that the sample will not be damaged by overpressure

With over-voltage protection, menu-style setting is adopted. And there are Chinese alarm prompts and sound prompts


Zero protection: The potentiometer should be reset to zero to boost the voltage. Prevent the high-voltage terminal from having voltage, causing harm to people and instruments


There is zero protection, and there are Chinese alarm prompts and sound prompts


Grounding protection: When the instrument is not grounded or is not well grounded, the instrument should have a grounding alarm and a corresponding prompt. And can not increase the pressure to prevent harm to people and instruments


There is grounding protection, and there are Chinese alarm prompts and sound prompts, under special circumstances (such as cable test site, generator power supply occasion). When testing without reliable grounding, long press the 75% function key to release the protection, which is convenient for users to test on site


Open circuit protection of internal voltage measurement circuit: when the internal voltage measuring resistance is open, the voltage measurement signal line is open, or the contact of the cable terminal is not good. If there is no protection, the instrument voltmeter has no indication at this time. The high voltage terminal has voltage, which may cause injury


The DC high voltage generator has internal voltage measurement loop open circuit protection. And there are Chinese alarm prompts and sound prompts
