Static Control Products - Constant Monitors


Dual Conductor Continuous Resistance Monitor, Network Ready- CM2815

 

Description

 

The Ohm Metrics' CM2815 Series 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 CM2815 is an extremely sensitive and reliable ground monitoring unit for use in highly critical areas.


The CM2815 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: 35MΩ
  • Mat Alarm: 100MΩ
  • 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

Applications:

Hard drive manufacturing / GMR head testing / Electronics assembly / Aerospace / Military / Semiconductor Fabrication / Any static sensitive assembly and test environment

CM2800-D Digital Display Unit for the CM2815

CM2800-D is a digital display device to be used with a CM2800 monitor. It displays the results that CM2800 measures in a real-time so that the users can observe the accurate measurements of the monitoring status. Using these external control interfaces, the user can connect the warning of each operator to an external siren.

CM2800-H High Speed Network Router for the CM2815

CM2800-H is a dedicated network router to be used with a CM2800 dual wire ESD moni-tor. It has 4 connection ports each of which can connect to a maximum of 32 CM2800 monitors. A maximum of 128 monitors can be connected to this Router. The Router con-tains an RJ45 port that can connect to a LAN through TCP/IP. A special high speed proc-essing technique is used in the Router to pro-vide high performance data processing and communication amongst networked monitors and the host PC-based network management software.

CM2800-IMS, Monitor Network Control Software

The CM2800-SEE is a dedicated program designed for the hardware management of the CM2800 networkable dual wire ESD monitor. It is an independ-ent PC-based control program that communicates to the monitor through an RS-232 port and an RS-232/RS-485 converter to exchange commands and data at high speeds. For any CM2800 model, all its supported monitor functions can be re-configured dynamically through this easy to use CM2800-SEE program.
