CO2 Monitor Operation 2 Operation 2.
Operation CO2 Monitor 2.2 Connecting Gas-Sample & Exhaust Lines 2.2.1 Connecting the Gas-Sample Probe To connect the gas-sample probe to the monitor, simply push the elbow connector into the Gas Sample Port on the front of the monitor as shown in the illustration below. The gas-sample line can be up to 50 ft (15.2 m) in length. All tubing bends should have a radius of no less than 5” to ensure proper airflow. If kinks or obstructions occur in the line the monitor may not function properly.
CO2 Monitor Operation 2.3 General Operation WARNING: Operate the monitor in its horizontal position (handle facing upwards). Tilting the monitor to a vertical position while in operation may cause inaccurate measurements to occur. To turn ON the monitor, lift up the shield located in front of the handle and press the ON/OFF toggle switch. When the monitor has been powered ON, allow it to warm up for 5 minutes. MEASURE indicates when the monitor is actively measuring gas.
Operation CO2 Monitor 2.4.2 Starting a New or Continuing TWA/twa When the monitor is turned ON the following message appears if the monitor is set up to display TWA/twa. Press either . . . • ENTER to start a new TWA/twa • ESC to continue with the current TWA/twa. Tip: If NO button is pressed within 60 seconds the monitor automatically continues with the current TWA/twa. NOTE: During the time the monitor is OFF, the gas measurement is assumed to be zero and will be factored into the TWA/twa calculation.
CO2 Monitor Operation 2.8 Battery – Charging and Using IMPORTANT: If you replace the original PGM-IR battery, refer to the installation instructions included in the replacement kit, as the new replacement battery and cable may differ from the original cable and battery. IMPORTANT: Cables and sockets are sized appropriately. As general rules of thumb: • Note the initial orientation of your power cable, and • Never force a connector into a socket. 2.8.

CO2 Monitor Operation 2.10 Gas Alarm 2.10.1 Gas-Alarm Light If the detected gas level reaches one the gas-alarm levels as set by the LEAKLVL, SPILLLVL, or EVACLVL functions, the front panel ALARM light will flash and the audible alarm, if activated (refer to AUDALRM function page 11), will start beeping. The ALARM light and audible alarm will automatically turn OFF once the detected gas level drops below the gas-alarm level. 2.10.
Operation CO2 Monitor 2.11.4 Fault Codes FAULT CODES ARE ADDITIVE. For example: A fault code of <0003> indicates that both a Box Temperature Fault <0001> and a Bench Temperature Fault <0002> have occurred. Code Fault Name Description <0001> Box Temperature Fault Enclosure temperature is outside normal range (or IR detector has failed). Check that the monitor is not being subjected to extreme temperatures. Use the DIAG function to check the Box Temperature.
CO2 Monitor Operation 2.13 The DIAG Function 2.13.1 Overview The DIAG function displays sensor data and status information useful to a service technician for troubleshooting various fault conditions. Explanations of the data shown in these screens are given below. 2.13.2 Keypad Functions From the Data Display screen, enter the Function Menu screen.

Operation CO2 Monitor 2.16 Downloading Stored Data to a Personal Computer Using the monitor’s PC DUMP feature, the last 200 gas readings that were stored in memory can be downloaded to a personal computer in ASCII text, comma-delimited format, which can then be imported into most spreadsheet programs for analysis. ® The following describes how to download data to a computer using Windows HyperTerminal as the communications program.
CO2 Monitor Operation 4. From the Data Display screen, enter the Function Menu screen. Next, use the Keypad buttons to move the arrow (>) until it points to PC-DUMP, and then press the ENTER button to begin the download process. 5. Observe that the monitor’s screen goes blank and that HyperTerminal displays the data as it is being received. After all data has been transmitted, the CO2 Monitor re-displays the Function Menu screen. 6.
