Monitor 2800 1.0 INTRODUCTION General The Bacharach CO Monitor Model 2800 is easy to use, but it is essen- tial that these Operating Instructions are read prior to use. The CO Monitor 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.
Monitor 2800 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 CO level to increase and may cause the instrument to alarm.
Monitor 2800 2.0 OPERATION Reading Mode When the instrument is switched on, there will be a 20 second (approxi- mately) warm up time before the CO level 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.
Monitor 2800 3.0 MAINTENANCE Battery Low When the battery voltage falls below a predetermined level, the screens will alternate between the following: Low Batt PPM CO2 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.
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 CO calibration.
FAULT If the fault condition warning is activated at any time, then the unit must be returned to Bacharach for service. Data Logging When the CO Monitor is switched on, it will automatically begin storing time, date and CO levels at 30 second intervals.
