Hipot Test(High Potential Voltage Test) means to test the product wheater there occurs the weakness to the high voltage or remains some materials which reduces electric insulation and the endurance against between 2 points that must be separate.
This test is done with 2 ~ 5 times higher AC voltage than the operating voltage of the product - under - test.
Hipot test must be done to all products to figure out the electric insulation for the quality control.
Function of the real time test.
: This tester has many I/O ports to make easy to communicate with other test systems.
(Start, Reset, Busy, Good, Bad, Low error, etc)
Real time test is a signal input terminal which makes able to proceed the test during the external signal comes
on to the tester.
When if these terminals are short, test procedure goes on, and if these terminals are off state, test stop.
It makes easier mass product test or temporary test stop.
This tesetr has 2 ground lines, and these lines must be to each other just on the product-under-test contacted to stout the test proceed.
If these 2 ground lines are not contacted to each other, the test procedure stops and low error lamp works.
The final purpose of this function is to avoid not only the product is judged as good when the ground line is not contacted to the product, but also to alarm the danger of ground open.
This tester does not tuse the pysical ON/OFF switch, but zero cross detect SSR switch, which reduces the unnecessary noise or impulse.
And photo couplers are used in all I/O ports(test, start, reset) to decrease the noise too.
Calibration Certificate issued
: All products that KAST delivered bring out the calibration certificate result together under the rule of ISO
17025.
