• 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
• 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. 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
