Page 3: Introduction
INTRODUCTION Thank you for purchasing the ESSAN‐01 Pocket CO2 Monitor and Data Logger. This personal, battery operated carbon dioxide (CO2) monitor is designed to monitor CO2 levels indoors or in confined spaces. Normal indoor air quality levels are shown by Green (good), Yellow (normal) and Red (warning) LEDs. If dangerously high CO2 levels are detected, the monitor will alert the user to immediately seek fresh air with a combination of visual, audible and vibrating alarms. This ... -

Page 5: Operation
OPERATION For daily operation, you should only need to perform 3 steps: power the monitor on, verify that the battery is charged, and perform a bump test. Power Button 1. Press the power button to turn the monitor on. 2. When the monitor is on, press the power button for 3 seconds to turn it off. When the monitor is initially turned on, it will perform a 5 second countdown, then display the current CO2, temperature, and humidity levels. The monitor starts taking measurements when powered on, and will update the display every 3 seconds until it is powered off. Check the battery level indicator on the LCD. If you do not have at least half a battery in the display, the monitor may not have enough power to run for a full day. Note: To conserve power, the LCD backlight turns off automatically after 5 seconds of inactivity. Press any button to turn the display on again. Daily Bump Test “Bump Test” is an industry term for verifying that the monitor will sound the alarm when it senses high levels of CO2. While you are encouraged to perform a full bump test daily, at a minimum you should perform a quick bump test daily before entering any enclosed areas. Full Bump Test 1. Turn the device on and wait for it to complete the 5 second warm up cycle. 2. Use 5% CO2 calibration or test gas with the balance nitrogen. Gas can be purchased online, or by contacting CO2Meter at (386) 872‐7665. 3. Note: 5% CO2 gas can be dangerous. Do not bump test in an enclosed area! 4. Place the tubing from the calibration gas directly on the back left hand side hole near the clip, this hole is directly above the sensor. Turn on the gas. 5. The alarm will sound depending on the alarm level you set. By default, the alarm is factory set at 5,000ppm. 6. Remove the tubing and turn off the gas. As the CO2 gas inside the case is displaced, the CO2 level will return to normal. 7. -

Quick Bump Test The quick bump test will only work if the alarm is set to the factory default of 5,000ppm. 1. Turn the device on and wait for it to complete the 5 second warm up cycle. 2. Place the top end of the monitor close to your mouth and breathe into the holes repeatedly. 3. The CO2 in your breath will cause the CO2 in the case to increase. Continue to blow until the alarm sounds. You can verify this on the screen. 4. Stop blowing. As your breath inside the case is displaced, the CO2 level will return to normal. 5. If the monitor does not pass the bump test, do not use it. First, perform a full bump test. If the full bump test fails, contact CO2Meter support at (386) 256‐4910 or e‐mail us at support@CO2Meter.com MENU OPTIONS Press the Menu button to enter the menu mode. There are 5 menu pages: Alarm, Temperature units, Calibration, Altitude and Data Logging. Press the Set/Home button ... -
Page 7: Set Temperature Units
Place the tubing from the calibration gas directly on the back left hand side hole near the clip. This hole is directly above the sensor. Run the nitrogen until the ppm level on the LCD displays approximately zero ppm. Note: the screen may show a warning for humidity error. This is normal during the calibration process. 1. Press Menu 3 times to select calibration. 2. Press Next to select Yes. 3. Press Set to begin calibration. Calibration takes 5‐10 seconds. 4. “Calibration succeeded” will appear once calibration is complete. Turn off the gas and let the monitor stabilize. It will return to the normal indoor CO2 level. Two different ESSAN-01 monitors may show different CO2 levels after calibration. If they are within 40ppm ±3% of the actual CO2 level, they are within the sensor’s specifications. To quickly verify the calibration, you can take the monitor outdoors. If the Altitude is set properly, the CO2 level should drop to approximately 400ppm depending on your location 7 ... -
Page 8: Altitude Correction
4. Altitude Correction The CO2 level displayed is affected by the altitude. This monitor is shipped with the altitude set at sea level (zero feet). If it is used at a higher altitude, you should first correct for altitude to insure maximum accuracy. Once the altitude correction is set, it will be saved in memory. See Appendix B for more information. 1. Press Menu 4 times to select Altitude Correction. 2. Press Next to raise the altitude in increments of 500 feet (150 meters) above sea level until the closest altitude to yours is reached. When altitude reaches 20,000 feet, it will return again to zero feet. 3. Press to save the current altitude setting and return to normal display. 5. Data Logging The date, time, CO2, temperature and relative humidity are continuously recorded every 30 seconds while the monitor is powered on. A total of 65,520 records (approximately 22 days) can be stored. If the memory is not reset, it will “roll over” and new data will overwrite the memory beginning at the oldest record. 1. Press Menu ... -
Page 9: Data Logging Software
DATA LOGGING SOFTWARE Included with your monitor is our GasDataLogging Software. This Windows PC program allows you to view the stored data offline with a user‐friendly graphical interface.

Page 17: Appendix A: Co2 Levels And Guidelines
APPENDIX A: CO2 LEVELS AND GUIDELINES 1. CO2 Alarm Guidelines The Occupational Safety & Health Administration (OSHA) requires by law that workers must be protected from potentially dangerous high levels of CO2. There are 3 CO2 safety limits that must all be followed: 5,000 ppm CO2. This is the OSHA exposure limit for CO2 averaged over a 40 hour week. 5,000 ppm CO2 TWA (Time‐weighted Average). A workplace is considered unsafe if workers are subjected to an average of 5,000 ppm CO2 or above for an 8‐hour workday. 3% CO2 STEL (Short Term Exposure Limit). At this CO2 level, an alarm must sound immediately and workers/occupants must leave the area. Visit www.osha.gov for more details and to determine which alarm settings are best for your application. 2. Indoor Air Quality The Green/Yellow/Red LEDs are provided as a quick check of indoor air quality (IAQ) in schools, offices and similar buildings. -
Page 18: Appendix B: Altitude Correction
APPENDIX B: ALTITUDE CORRECTION CO2 sensor modules are calibrated at sea level, and are not designed to automatically compensate for changes to CO2 at higher altitudes. The CO2 level will be approximately 3% lower for every increase of 1,000 feet (300m) in altitude. For example, at 5,000 feet a meter reading 400 ppm calibrated at sea level would read approximately 340 ppm. Rather than making this calculation each time you use the monitor, you can look up your location’s altitude online and enter the closest value into the monitor’s menu settings. Then the ... -
