The CM300 not only eliminates time consuming wrist strap testing, it removes the danger of wrist straps failing in the field and possibly exposing highly sensitive materials to static. Both audible and visual alarms signal when the wrist straps fail. Enclosed in a durable metal case with built in mount-ing brackets, the monitors can be installed underneath table tops to save work space. The CM300 series monitors meet or exceed the recommendations of ANSI ESD S20.20.Why Use Constant MonitorsThe first and best line of defense against static damage is wrist strap grounding, but these wrist straps wear over time and must be tested to ensure they are working properly. ESD Constant monitors reduce production costs by eliminating the time spent on testing wrist straps before each shift. Further savings may be realized by reduced ESD damage from broken wrist straps.Capacitance TechnologyThe CM300 sends out a signal through the wrist strap that detects the capacitance of the person and ground. When both are present, the monitor goes into an unalarmed state. If the electrical connection to the person or to ground should fail, the circuit will go into the alarm state to signal there is a problem.CalibrationThe CM300 constant monitors are factory calibrated and will never need recalibration. It is a fixed resistor system and is go no go, there is no calibration needed. You can verify proper working conditions with the CM410PV periodic verification. ... Show More Show Less
