The IR425 is designed to monitor insulation resistance of ungrounded AC/DC control circuits from 0–300 volts. Operating on the AMP (Adaptive Measuring Pulse) principle, the A-Isometer IR425 initiates an alarm when the control wiring of a mining machine and its frame ground falls below preset response values.
