Two Operator  and Mat Single Wire Monitor                       
The  Ohm Metrics CM1600 dual conductor workstation monitor continuously  checks two  operators and two work surface ground connections. When a  person is wearing a wrist strap, the monitor observes the resistance of  the loop, consisting of a wire, a person, a wrist-band, and a second  wire. If any part of the loop should open (become disconnected or have  out of limit resistance), the circuit will go into the alarm state. An  important feature of the Dual Wire Wrist Strap is that even if one  conductor is severed, the operator has reliable path-to-ground with  other wire. The CM1600 packaged in a stainless steel case with remote  jacks.
 
The CM1600 is an extremely sensitive and reliable ground monitoring  instrument. Audible and visible alarms are triggered if the operator’s  resistance exceeds 35 megohm (factory default). Low resistance can also  triggers an alarm event. Mat alarm limits are set at 100 meg ohm.
