A ___________ monitor provides continuous assurance the wrist strap is working and alarms immediately when a disconnect from the technician to the ground occurs.
Correct Answer:
Megohmmeter
Explanation:
Continuous monitoring of the operator’s grounding path is provided by a wrist strap monitor. This device is placed in-line with the wrist strap and ground cord and constantly checks the connection to earth. If the strap becomes disconnected or the path opens, it immediately triggers an alarm so the technician can reconnect before continuing. Other tools serve different purposes: a ground impedance tester checks the impedance of the grounding path but isn’t used for real-time monitoring during work; a megohmmeter measures high resistance for periodic insulation checks; a charge plate monitor verifies surface charging, not the strap connection. So the description points to a wrist strap monitor.
