• 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.
• NEW Monitored Ground Terminal
  Provides a verified ground point for mats, carts, tools, and other items. Connect with the 09842 Multi-Ground Hub.
• NEW Light Tower Jack
  Connects with 19332 Light Tower Accessory
• NEW Auxiliary Jack
  Connects with 19333 Power Relay Accessory
• 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
• 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
• Park Delay Timer and Park Snap
  Indicates the 8 second delay to disconnect and park the operator wrist cord without creating a false alarm
• Embedded Relay Terminal
  Activates when a failure is reported by the monitor. Integrates with electronic locks, lights, and buzzers.
• Mat Monitor Switch
  Disables the worksurface monitor circuit when used in areas where there is no ESD worksurface
• Audible Alarm Adjustment
  Sets the audible alarm volume from loud to louder
• Enclosure with Mounting Tabs
  Installs in workbench and equipment environments
• 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. For more information on the calibration of Desco products, see Calibration.
• 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

Technical Information

*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.
