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. Utilizing low-voltage, resistive loop technology, and
dual conductor ground products, the CM2800 is an extremely sensi-
tive and reliable ground monitoring for use in highly critical areas.
The CM2800’s alarm settings can be reconfigured quickly and easily
with the optional PC software CM2800-SEE. Operator Resistance,
Operator Voltage, Work-surface Resistance, Operator Presence
Check (OPC) and Resistance of Equipment alarms can be enabled/
disabled and limits selectable to user specifications.
The CM2800 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 al-
lows 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.
Features:
 Monitors two wrist straps, work surfaces and tools.
 User programmable alarm levels
 Network Ready
 Ultra-Low voltage for highly critical areas.

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.
Alerts
If any parameters exceed the preset high limits, the corresponding LED
on the front panel of the monitor will change color from green (OK) to
red (high warning) to indicate the abnormal situation. If the resistance is
below preset low limit, the LED color will be yellow (low warning).
An audible alarm will sound, in addition to the corresponding LED indi-
cator when the resistance is in an abnormal state. For instant differen-
tiation, a single beep will sound if the abnormal situation occurs on
“Station 1” whereas a double beep sound for “Station 2”.
(LED indicators illustration of GZ-1800 front panel.)
 “OP 1” - Grounding resistance of operator 1
 “OP 2” - Grounding resistance of the operator 2
 “V1” Induced voltage on operator 1 .
 “V2” Induced voltage on operator 2.
 “MAT1” Grounding resistance of work surface 1
 “MAT2” Grounding resistance of work surface 2
 “G1” Grounding resistance of tool 1
 “G2” Grounding resistance of tool 2

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 resistance of
the wrist strap is below preset low limit, the LED will turn YELLOW
and alarm. If the wrist strap is not plugged into the remote termi-
nal jack, the LED’s of both “OP” and “V” will be off to indicate the
stand-by mode. Factory set resistance limit is 1.8 megohm. De-
fault Voltage limit is 2V .
Since the CM2800 is designed with a Ultra-Low Voltage circuit, the
measurement voltage of the grounding resistance of the operator
body can be as low as 0.2V. Therefore, when the low resistance of
the wrist strap is measured, it may be affected by the small
“Battery Effect” existed between the contact of the human body
skin and the wrist-strap metal stud. To avoid this, the the low resis-
tance measurement is disabled by default. If this measurement is
turned on and the value is affected, you can reverse the direction
of the wrist strap stud to resolve the influence.
Operator Presence Check (OPC) Alert
Stand-By Mode (or “idle mode”) is when the monitor is powered
on, and there is no wrist straps plugged in to the remotes. At this
time, the monitor will start Operator Presence Check (OPC) if en-
abled. OPC is a pre-programmed count down that will trigger an
alarm if the operator does not plug in the wrist strap into the re-
mote jack in the specific time. The LED of “OP” and “V” will turn red
and flash to indicate an OPC warning. OPC warning will stop after a
wrist strap is plugged in to the remote.

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” jack is not, but provides a grounding
path for one more wrist strap. The status of “AUX” will not affect
“OP”.
2. ESD Mat
The CM2800 can monitor the ground resistance of two dissipative
surfaces. When the resistance is within acceptable limits, the LED
labeled “MAT” will be GREEN. If it exceeds preset high limits, the
LED will change to RED and an alarm will sound. Factory limits are
set at 100 meg ohm.
3. Tool
The CM2800 monitor measures the low value grounding resistance
of equipment or a tools in the range of 2 to 20 Ohm. Typical exam-
ples of equipment are electronic microscope or test instruments.
When the resistance is within acceptable limits, the LED labeled “G”
will be GREEN. If it exceeds preset high limits, the LED will change
to RED and an alarm will sound. Only 100 microamperes of current
are used for this measurement, and as a result only 4mV of poten-
tial is induced on the instrument being monitored.

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.
1. Install monitor in a location where alarm indicators will be visi-
ble and alarm will be audible to operator. Typical locations are
under a workstation table or low shelf.
2. Mount monitor securely in place with Velcro.
3. Install remote wrist strap terminals in a convenient location for
operators. Frequently remotes are mounted on the underside
of the workbench nearest operators.
5. Plug the telephone cable from the left remote to the OP1 on
the back of monitor.
6. Plug the telephone cable from the right remote to the OP2 on
the back of monitor.
7. Connect the bare end of the FM1515CM wire to the terminal
on the back of the monitor labeled GND and connect to
GROUND. See wiring diagram.
Mat Set Up: If no grounded ESD mats are to be monitored, connect
a wire from both M1 and M2 terminals to the GND terminal on the
back of the monitor and skip steps 8 and 9.
8. Connect the FM1515NR cord from the first grounded Mat to
the terminal on the back of the monitor labeled M1.
9. Repeat step 8 with an additional FM1515NR (not-included) if an
additional mat is to be grounded. If not, connect a wire from
M2 to GND to disable alarm function.

6
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.
Tool Set Up: If there are no Tools to be monitored, connect a wire
from both G1 and G2 terminals to the GND terminal on the back of
the monitor and skip steps 10 and 11.
10. Connect a wire from the first Tool grounded connection to the
terminal on the back of the monitor labeled G1.
11. Repeat step 10 with if an additional tool is to be grounded. If not,
connect a wire from G2 to GND to disable alarm function.
12. Plug power supply into the PWR connector on the back of the
monitor and into the power line.

5. OP1/OP2 port is the connection to the wrist strap remotes.
There is an “I/O port” on the left-hand side of the CM2800 to support
an external relay box. The optional relay box provides 3 dry-contact
relays for OP1, OP2 and an external control port. When CM2800 is
power on, the NO and COM contact is shorted as the default setting of
external control port. When CM2800 is power off, the NO and COM
contact will be opened.
Calibration and Periodic Testing
Except the operator resistances, CM2800 never needs calibration. You
can verify proper operation of the monitor by periodically testing the
monitor with a resistance limit comparator box CM2800PV. Every
CM2800 unit is calibrated at factory to meet the following criteria:
Operator Resistance: ±10%
Operator voltage: ±10%, or within 3 counts at 2V or less
Mat resistance: ±10%
Tool resistance: ±10%, or within 3 counts at 5Ω or less
If you need to calibrate the operator resistance of your CM2800 unit,
please contact Transforming Technologies

The “OP1 OUT” dry-contact relay is activated along with the moni-
toring status of OP1’s resistance and voltage. When OP1’s resis-
tance or voltage exceeds the preset limits, the corresponding built-
in dry contact relay will switch from NC to NO. Every relay has 3
contacts with the center contact as common contact, the left con-
tact as NC (Normally Close) and the right contact as NO (Normally
Open). Each of these relays has contact rating of 1A at 30VDC, 2A at
120VAC, and 3A at 24VDC.
The “OP2 OUT”, “G1 OUT” and “G2 OUT” can be activated in a way
similar to “OP1 OUT”.
These relay contacts can
be used to control the
external devices such as a
tower siren or other ac-
cess control devices. In
the connection diagram
on the right, we illustrate
how to utilize “OP1 OUT”
to control an external 110V Green/Red tower alarm.
(Note: You need to reserve 250mA power capacity for each
CM2800 with digital display module CM2800-D among the inter-
linked units that share the same DC power adaptor. For example, a
1A DC power adaptor will be required if you plan to let 4 sets of
CM2800 + CM2800-D share one DC power.) These monitors are
interlinked with a special 10-feet communication cable provided by
Transforming Technologies with the Part# of GZ-485CABLE.
