Description:

The Desco Full-Time Continuous Monitor is a single workstation continuous monitor. It continuously monitors the wiring of an AC outlet, path-to-ground integrity of one operator, and the ground plane of one ESD worksurface. Mounting tabs make it suitable to install in workbench or equipment settings. The embedded relay terminal activates when a pass condition is displayed the monitor and maybe connected to machines for access control or other devices. Connect the 19323 Power Relay accessory to control power to workbenches, hand tools, and other electronic devices dependent on the Full-Time Continuous Monitor's status. The Full-Time Continuous Monitor is designed with Wave Distortion Technology to provide 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 500 milliseconds) when the operator unintentionally disconnects from the monitor or the wrist strap connection points are intermittent. The Full-Time Continuous Monitor also monitors for a worksurface path-to-ground of less than 10 megohms and the integrity of the electrical ground used to by the monitor All Full-Time Continuous Monitors are calibrated to NIST standards and include a certificate

Features of the Desco 19321 Montior:

  • Single Workstation Continuous Monitor
    Continuously monitors the path-to-ground integrity of one operator, one ESD worksurface, and the electrical ground used to by the monitor.
  • IMPROVED Operator Alarm
    Alarms when the operator unintentionally disconnects from the monitor or the connection between the banana plug and monitor’s jack is intermittent
  • NEW AC Outlet Monitor Circuit
    Verifies the wiring of an AC outlet and continuously monitors its path-to-ground integrity; fulfills the ANSI/ESD S6.1 section 6.3.1 requirement
  • NEW Park Delay Timer
    Indicates the 8 second delay to disconnect and park the operator wrist cord
  • NEW Embedded Relay Terminal
    Activates when a pass condition is displayed the monitor. Connect to machines for access control or other devices.
  • NEW Mat Monitor Switch
    Disables the worksurface monitor circuit when used in areas where there is no ESD worksurface
  • NEW Audible Alarm Adjustment
    Sets the audible alarm volume from loud to louder
  • NEW Enclosure with Mounting Tabs
    Installs in workbench and equipment environments
  • NEW 19323 Power Relay Accessory
    Controls power to workbenches, hand tools, and other electronic devices dependent on the Full-Time Continuous Monitor’s status
  • Wave Distortion Technology
    Provides stable continuous monitoring (versus pulsed or intermittent) of the wrist strap’s path-to-ground* and the presence of its 1 megohm safety resistor
  • Park Snap
    Allows the operator to disconnect (and park) a wrist strap when leaving the 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 the risk of electrical overstress (EOS) for the handling of sensitive components
  • <50 Millisecond Alarm Response Time
    Identifies failures and intermittencies
  • Continuous Visual and Audible Alarms
    Illuminates green to indicate proper grounding; illuminates red and sounds audible alarm when intermittent or failed connection occurs
  • Calibration Verification
    Use the Desco 98221 Wave Distortion Monitor Verification Tester to check the test limits of Wave Distortion Monitors without removing them from their workstations
  • NIST Calibrated with Certificate Included
    Calibrated with accepted procedures and standards traceable to the National Institute of Standards and Technology. 
  • 100-240VAC Input with North American Power Cord
    Works with standard electrical systems in North America, Japan, and Asia
  • Made in the United States of America

*The ESDA Wrist Strap standard is ANSI/ESD S1.1. The Wrist Strap System required limit per ANSI/ESD S20.20 Table 3 is 0.8 to 1.2 x 106 ohms with product qualification testing per ANSI/ESD S1.1. The test range of the monitored circuit is 500 kilohms to 10 megohms.
