Note :
1. "+" HV output terminal: it is also called a line terminal; it uses
2. high-voltage cable to connect measured target such as the transformer,
motor windings and cable cores.
2. "Guard" protection terminal: when using “three-electrode method”
measure the volume resistance of insulation material and cables, "G" should
be connected to three-electrode guard ring. Guard ring is used to eliminate the
