Notes

Before reversing the tap connections in the test of no-load voltage regulating transformers, be sure to reset the tester, wait till the end of the discharge process and the alarm stops. Before removing the wires, be sure to wait till the discharge process completes and the discharge alarm stops.

When the three channels are used, because the initial establishment of the magnetic circuit may take longer when testing the first set of data, the stabilization time can be shortened when the tap connections are reversed.
