Ohm Metrics Resistance Monitor: CM2800 The Ohm Metrics' CM2800 Series dual conductor workstation moni- tor provides continuous monitoring of voltage and resistance for two wrist straps along with two mat and two workstation tool grounds. The status’ are displayed using tricolor LED’s on the front panel of the monitor and abnormal levels trigger an alarm to inform opera- tors on the line.

Operation The CM2800 monitors the grounding functions of a workstation and alerts users when levels are out of the set range. The CM2800 has the capabilities to monitor: Operators: Resistance and voltage of two wrist straps/personnel, Work surfaces: Resistance levels of two dissipative surfaces. Tools: Resistance levels of two grounded work station tools.

1. Operator Grounding The operator is grounded when the dual conductor wrist strap is plugged in to the jack labeled “OP” of the grey remote. The corre- sponding LED label “OP” and “V” will be GREEN if levels are normal. If the any of these parameters exceed preset high limits, the corre- sponding LED will turn RED and alarm will sound.

If the cable connecting to a wrist strap remote is unplugged or sev- ered at either end, the monitor’s audible alarm will sound, and the corresponding “OP” LED will turn red. Note: Each remote has two jacks labeled “OP” and “AUX”. The “OP” jack is monitored and “AUX”...
Installation Before you install your device, check for the items below: 1 - CM2800 workstation monitor 2 - Remote Jacks 1 - Power Supply 2 - Telephone Cables 3 - Grounding Cables: FM1515, FM1515CM, FM1515NR Please carefully read the following instructions before proceeding with product installation.

Note: The work surface mats have to be connected to the CM2800 with zero Ohm wire for proper mat monitoring operation. Using a wire with a 1M resistor may cause alarm. The FM1515NR is the pro- vided zero Ohm cord and more can be purchased from Transforming Technologies.
