Once charge and testing button, then capacitor is moved to and read data on test copper sheet.Its simple structure, it is easy to operate,
But without any safety insulating device between testing capacitor and tester, also without automatic current limiting or disconnection during capacitor short-circuit
Device, needs the manual power-off of personnel.If testing capacitor is short-circuit and personnel fail to find and deenergization, capacitor is possible to
Explode and cause security incident.It is unsuitable for testing the electrolytic capacitor of high voltage.
