CO2Monitor 2800
1.0 INTRODUCTION
1.1 General
The Bacharach CO2Monitor Model 2800 is easy to use, but it is essen-
tial that these Operating Instructions are read prior to use.
The CO2Monitor is designed to warn the user of increasing Carbon Diox-
ide levels in the range of 0 to 50,000 ppm. The unit is based on the Infra-
red absorption principle and has two preset alarm levels - normally 5,000
ppm and 10,000 ppm. When either of these levels is reached, a combina-
tion of audible and visual alarm signals will be activated until the CO2
level returns below the lowest preset level. It is a compact, easy-to-use
unit and can be hand-held or attached to a belt.
1.2 Main Features
• Audible and visual warnings if CO2exceeds preset levels.
• Easy to operate with user-friendly screen display.
• Easy calibration in clean air.
• Functional test mode.
• Fault condition warning.
The unit is normally supplied complete with a battery charger and oper-
ating instructions.
1.3 Battery
The battery should provide 8 to 10 hours of continuous use when fully
charged. When the BATTERY LOW indicator is activated, the unit must
be recharged as soon as possible using the battery charger (supplied)
which connects to the socket on the side of the unit.
1.4 Units of Measurement
Models are available with readout of CO2concentration in either parts
er millio (m) or % (uit must be recogured usig the otioal
BACH-COM Software). Please note that 1 % = 10,000 ppm and 0.01 % =
100 ppm.

1.5 Important Note
Always ensure that the sensor grille located on the front of the unit is un-
obstructed and open to the atmosphere. A quick instrument check can be
performed by breathing directly into the sensor grille. This will cause the
indicated CO2level to increase and may cause the instrument to alarm.

1.6 Cleaning
Keep the unit clean by wiping with a soft cloth dampened with a mild
detergent solution.
1.7 Sunlight
The unit should not be left out in direct sunlight, or in other areas where
excessive heat exists, for long periods since component damage due to
overheating may result.
1.8 Servicing
There are no user-serviceable parts inside the CO2Monitor.
Unauthorized disassembly of the unit will invalidate the warranty.

2.0 OPERATION
2.1 Reading Mode
When the instrument is switched on, there will be a 20 second (approxi-
mately) warm up time before the CO2level present in the atmosphere
surrounding the user is displayed. The ON/OFF button should be pressed
quickly when switching the unit on and held down for approximately 2
seconds when switching the unit off.
CO2 PPM CO2
MONITOR 300
Whe the uit has bee tured o, a “codece bee” will soud for
0.25 seconds every 30 seconds. This should NOT be interpreted as an
alarm condition. The unit has two preset alarm levels which are normal-
ly set to indicate the presence of Carbon Dioxide in concentrations above
5,000 ppm or 10,000 ppm (factory preset levels). The levels can be factory
set at customer secied levels, or ca be reset usig the BACH-COM
Software (See Section 4.1).
When the CO2level rises above the low alarm level:
• The dislay will show the cocetratio ad ash oce er secod.
• The Alarm LEDs will ash oce er secod.
•The beeper will sound intermittently once per second.
When the CO2level rises above the high alarm level:
• The dislay will show the cocetratio ad ash oce er secod.
•The Alarm LEDs will be lit continuously.
•The beeper will sound continuously.

3.0 MAINTENANCE
3.1 Battery Low
When the battery voltage falls below a predetermined level, the screens
will alternate between the following:
Low Batt and PPM CO2
300 300
In addition, the alarm will emit three rapid tones every 30 seconds. The
unit must be given a full charge as soon as possible. Charging time is
between 1 and 1.5 hours. Once the unit is fully recharged, it will emit a
constant beeping tone for 30 seconds and display:
CHARGING then CHARGED

3.2 Air Calibration
The unit can be calibrated, approximately, in clean outside air (assumed
to be 340 ppm CO2) by pressing and holding down the f2button for a
minimum of 3 seconds. It is essential to ensure that the unit is in clean
air before attempting an air calibration. If this condition is not ensured,
incorrect readings will be obtained. Be careful that your breath does not
affect this air calibration procedure. A 340 ppm calibration gas cylinder
can be used (See Section 4.1 for a list of Calibration accessories).
Hold the f2button down and the following sequence of displays will ap-
pear.

The gas display screen will reappear after the f2button has been re-
leased. If the calibration was unsuccessful, or if the f2button was re-
leased prematurely, then the display will show the following:

Instruction 19-9220
CO2Monitor 2800
If this happens, retry the Air Calibration procedure, ensuring that the
unit is only exposed to clean outside air. If the procedure is still unsuc-
cessful then the unit must be returned to a Bacharach Service Center
(see Section 4.2) for evaluation. This procedure will provide a good low
end CO2calibration.
3.3 Calibration Using Higher Gas Concentration
The unit should be checked periodically with a higher concentration of
CO2gas, depending on usage (every 3-6 months). Check the unit with a
gas typically in the 1.5 to 3.0% CO2range using the optional Calibration
Accessories (Section 4.1). Accuracy should be ±10% of reading.
If during the calibration check, the instrument reading is outside of the
tolerance of the check gas used, the instrument can be returned to a
Bacharach Service Center (see Section 4.2) for recalibration.
3.4 Test Mode
To activate the TEST MODE, switch the unit on, and then press and
hold down the f1button. Both LEDs will illuminate and the alarm will
sound. The following screen will be displayed:
TestMode
Power
Provided that both alarm LEDs illuminate, the alarm sounds and the
display is as shown, the unit is ready for operation. If any of these func-
tions are NOT operating correctly, the unit must be returned immedi-
ately to Bacharach for service.
In the lower part of the Test Mode screen is a bar graph showing the ap-
proximate amount of battery power available. As the power in the unit
reduces, the bar graph decreases in size.

3.5 Fault Condition Warning
The unit can warn the user of an internal fault, i.e. a source failure or
blockage in the Infrared path. When a fault occurs, both LEDs will illu-
minate and the alarm will sound continuously. The following screen will
display until the unit is switched off.
FAULT
If the fault condition warning is activated at any time, then the unit
must be returned to Bacharach for service.
3.6 Data Logging
When the CO2Monitor is switched on, it will automatically begin storing
time, date and CO2levels at 30 second intervals. Optional BACH-COM
Software allows this interval to be changed (Section 4.1).
Readings are stored with their real time to the nearest second. There is
storage capacity for more than 1,500 sets of readings. Once the storage
capacity has been exceeded, the latest readings will overwrite the oldest
stored data - i.e. rst i, rst out.
NOTE: Optional BACH-COM Software is available to pro-
duce tables and plots of real time CO2exposure (See Section
4.1 for part numbers).
3.7 Software Version/Serial Number
While holding the f1button down, turn the unit ‘on’ in order to retrieve
the instrument software version and issue date. Releasing the f1button
will dislay the istrumet serial umber for ve secods.
3.8 Factory Authorized Reset Mode
This function should only be activated when advised by a Bacha-
rach service representative as it may alter calibration.
While holding down f2 butto, tur uit “o”. The dislay will show...
