Instruction Manual
CM400 Installation Diagrams
- Mount monitor under bench area (use included screws or Velcro).
- Plug in the AC power supply to monitor and grounded 110v to an outlet. (monitor grounded through AC Adapter)
- Operator LED should be RED and alarm will sound 1 long
- With wrist strap worn correctly while plugged into moni- tor, LED will go from RED to GREEN when in use indi- cating grounding is functioning.
Operation
Monitoring begins when the coiled cord of the wrist strap is plugged into the monitor or remote jack. The status of a wrist strap resistance is indicated by a the bicolor LED and audible Alarm:
Stand-by indication.
If the wrist strap is removed or not being worn but is still plugged into monitor, an audible alarm will sound for 4-6 seconds, and the “OP” (operator) led will be will be blink RED.
Normal indication.
For normal operating resistance “OPER” led will be
GREEN.
High alarm.
If the operator wrist strap is plugged into the remote and resistance is higher than maximum, the “OPER” led will be RED and audible alarm will sound.
Calibration and Verification
The CM400 is factory calibrated and fixed. It does not require re-calibration. It is recommended to verify proper operation with the CM410PV verification unit available from Transforming Technologies.
