Uninterruptible polarity switching function of the Leak Current HiTester

QWhat is the "Uninterruptible Polarity Switching function" of the Leak Current HiTester ST5540?

A

Leak Current HiTester ST5540 can perform measurements that simulate power supply polarity switching of a measured object.

When switching the power supply polarity, the "uninterruptible polarity switching function" allows the test to be continued without shutting down the object being measured, thereby shortening the test time.

When using the uninterruptible polarity switching function, be sure to use an isolation transformer.
