Optocoupler insulation test

Current accuracy of 100pA Rise time less than 10ms fall time less than 50

For the test of the optocoupler's voltage resistance performance, use a high-voltage power supply to perform a voltage resistance test on the optocpler's input and output. Ensure that the test voltage is within the optocoupler's rated voltage resistance range to check whether the optocoupler can operate normally high voltage conditions.
