Continuous monitors pay for themselves, by improving quality, productivity, and eliminating daily wrist strap testing and test result logging. Per ESD-S1.1 paragraph 6.1.3 Frequency of Functional Testing, "The wrist strap system should be tested daily to ensure proper electrical value. Daily testing may be omitted if constant monitoring is used."

Per ESD Handbook TR20.20 paragraph 5.3.2.4.4, "Typical test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, and then continuous monitoring should be considered or even required."

The Desco EMIT Dual-Wire Dual-Operator Programmable Monitor can maintain two work surfaces and two operators at ground potential to virtually eliminate the risk of ESD damage. The highly visible LED display and audible alarm makes it easy to monitor the status of the work surfaces and operators. The Dual-Wire Dual-Operator Programmable Monitor uses Desco EMITÆs patented dual resistive loop technology. No other method is as direct and reliable. Both work surfaces, and individual operator resistance limits, can be programmed and reconfigured as required. If the ground potential of either work surface or operator is lost the, monitor immediately alarms (both audible and visual). The monitor is unaffected by capacitance variations associated with personnel and environmental conditions.

Features:

• Dual Wire Continuous Monitors provide redundancy; even if one dual wire wrist strap conductor is severed, operator has reliable path-to-ground with the other wire.
• Patented Resistance Loop Monitoring Technology
• Monitoring of two operators and two ground connections independently
• For use with dual-wire wrist straps
• Adjustable alarm level
• Independent alarming conditions: audible and visual
• Resistance, programmable, no manual adjustment necessary
• Visual display for all status

Note: Work surface must have a conductive layer such as Dual Layer Rubber or Dissipative 3-Layer Vinyl or Micastat® Dissipative Laminate with conductive buried layers. Our Continuous Monitors are not recommended for use with homogeneous matting.
