Desco 19239
Continuous Mini Monitor, North American Plug
The Desco 19239 Continuous Mini Monitor (North America Plug) features an operator alarm which sounds when the operator unintentionally disconnects from the monitor or if the connection between the banana plug and monitor's jack is intermittent. The wave distortion technology provides stable continuous monitoring of the wrist strap's path-to-ground.
- Single-wire impedance design
- Park snap for disconnecting wrist strap
- NIST calibrated
- Continuously monitors path-to-ground integrity of one operator and one ESD worksurface
- Produces alarms for when operator unintentionally disconnects from monitor or connection between banana plug and monitor's jack is intermittent
- Provides stable continuous monitoring (versus pulsed or intermittent) of wrist strap's path-to-ground and presence of its 1 megohm safety resistor
- Park snap allows operator to disconnect (and park) wrist strap when leaving workstation without creating a false alarm
- Single-wire impedance design meets ANSI/ESD S20.20 in accordance with ESD TR1.0-01-0
- 1.2 Volt operator test voltage reduces risk of electrical overstress (EOS) for handling of sensitive components
- <50 Millisecond alarm response time identifies failures and intermittencies that inferior technologies miss
- Continuous visual and audible alarms
- Illuminates green to indicate proper grounding
- Illuminates red and sounds audible alarm when intermittent or failed connection occurs
- Calibrated with accepted procedures and standards that are NIST traceable
- Includes 100-240 VAC power adapter with North American plug
The Desco 19239 Continuous Mini Monitor, North American Plug is a single workstation continuous monitor that continuously monitors the path-to-ground integrity of one operator and one ESD worksurface. The 19239 eliminates the need for periodic testing and record keeping of wrist straps. The 19239 Mini Monitor is designed with Wave Distortion Technology that provides stable continuous monitoring of the path-to-ground and presence of 1 megohm resistance of an operator's wrist strap. Audio and visual alarms activate (in less than 50 milliseconds) when the operator unintentionally disconnects from the monitor or the wrist strap connection points are intermittent. The Mini Monitor also serves as a ground point for an ESD worksurface and monitors for a path-to-ground of less than 500 megohms. It is calibrated to NIST standards and includes a certificate.
Wave Distortion Technology is the most reliable technology for the continuous monitoring of single-wire (conductor) wrist straps. "Wave Distortion" or vector impedance works by applying a continuous test voltage of 1.2 volts peak-to-peak at 1 to 2 microamperes (0.000002 amperes) to the wrist strap that is connected to the continuous or constant monitor. The test voltage creates a sine wave that the monitor circuit compares to established patterns. By monitoring the "distortions", or shape of the sine wave, Wave Distortion Technology determines if the monitored circuit is complete - the operator is in the circuit and the total equivalent DC resistance is within specifications. Wave Distortion Technology produces a very fast alarm time (<50 milliseconds) and minimal false alarms.
