How much v is needed for medical electronic blood pressure meter leakage current test

The test power supply voltage of different electrical appliances is different, the insulation level is also different, there is no special requirements, electrical appliances, the withstand voltage will not exceed the working voltage of 3 to 5 times, that is to say, the measurement of low-voltage line insulation can only be used with low voltage. For example: 220V line, can only use 500V shaking table to measure the insulation, if the use of 2500V shaking table measurements, may be the line insulation breakdown caused by line damage.
