Typical application:

High voltage isolation safety test method and precautions:
1. Reffering to the wiring shown in the above figure, setting the rated high voltage value of the high voltage tester according to the product isolation voltage parameter specification. Please pay attention to personal safety when testing, beware of electric shock!
Test environment: room temperature TA = 25 ° C, air humidity < 75%
2. The high voltage test operator must wear rubber-insulated gloves with rubber insulation pads on the ground to avoid high voltage electric shock.
3. The instrument housing of the high voltage tester must be grounded reliably and should not be detected in a high temperature, humid and dusty environment.
4. When connecting the measured object, the high voltage tester must ensure that the high voltage output value is "0" and the detection function key is "reset" to prevent contact with other objects.
5. When the instrument is in the high voltage test state and before the end of high voltage discharge, it is strictly forbidden to contact the measured object, test line or high voltage output.
6. Product isolation voltage test method as shown in the above figure, short the input terminal and output terminal pin respectively and load the rated voltage value for 1 minute.
7. According to the rated isolation voltage value of the product, use the output voltage of the manual gear to adjust tester from 0 to the rated value and keep it for a minute.
8. The insulation voltage test itself is a destructive test of the insulator. For the same product, the high voltage test should be minimized. If there are multiple tests between different customers, the general requirements are as follows: the batch product is tested according to the rated voltage value of the specification for the first time, and the test voltage value should be reduced by 0.7 times of the rated value each time. The number of high voltage tests, otherwise the product will be irreparable damage during multiple high-voltage tests..
