Data Sheet
Owners Manual

RangerBOSS Dual Wire Constant Monitor is a data-logging dual wire constant monitor for up to two people and two work surfaces with adjustable alarm limits.

The RangerBOSS dual conductor workstation monitor provides complete ESD protection to two operators by monitoring both resistance and voltage independently using dual conductor wrist strap. It also monitors ESD mat ground and low resistance of tool chassis’ ground simultaneously. Utilizing ultra-low voltage, resistive loop technology, the CM2800 is an extremely sensitive and reliable ground monitoring unit for use in highly critical areas.

The RangerBOSS’s alarm limits are user programmable via the optional PC software CM2800-SEE. Operator Resistance, Operator Voltage, Work Surface Resistance, and Resistance of Equipment alarms can be enabled/disabled and limits selectable to user specifications.
The RangerBOSS is network ready and can easily be connected to other workstation monitors and a computer using the high-speed network router, CM2800-H. The host computer can be transformed into a command center with the software CM2800-BOSS SEE, a central monitoring program that shows real-time grounding results and allows for adjustment of alarm parameters of up to 4096 workstations. An entire assembly line’s ESD protection can be remotely monitored and adjusted with one computer.

Proactive Key Functions:

  • Wrist-strap Alarm: High Limit: 8MΩ ~ 35MΩ (35m default); Low Limit: 750KΩ ~ 2.4MΩ
  • Operator Voltage Alarm: ±1V ~ ±5V
  • Mat Alarm: 1MΩ ~ 140MΩ
  • Tool Alarm: 2Ω ~ 20Ω
  • Via CM-2800-D, provide digital display on LCD. Also provide 4-20 mA or 0 – 5V analog outputs and external interfaces for siren and tool controls
