The insulation resistance meter is also called a megohmmeter , and its resistance value is in the megohm level. It is mainly used to measure the insulation resistance of motors and electrical circuits, to determine
whether there is leakage in the equipment or circuit, and whether the insulation is damaged or short-circuited.
~~
The main components of the insulation resistance meter are a magnetoelectric current ratio meter and -/a a hand-operated high-voltage DC generator as the measuring power source. The appearance of the insulation
resistance meter is shown in Figure 5-2a. The insulation resistance meter circuit is as shown in the figure
