Q: What is the continuous operating time?
A: The continuous operating time for each test should not exceed 1 minute; after that, the power should be turned off to allow the unit to cool down.
Q: What is the difference between DC and AC testing?
A: The wiring is the same; however, for DC testing, a high-voltage rectifier diode must be installed at the high-voltage output terminal, and the output voltage is 1.414 times the AC voltage.
