INTRODUCTION
Thank you for purchasing the SAN-0001 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
makes the monitor useful for both measuring IAQ as well as a personal CO2 level protection
device.
The SAN-0001 Pocket CO2 Monitor and Data Logger uses non-dispersive infrared (NDIR) CO2
sensing technology to provide long life, accuracy and stability in daily use. In addition to
measuring the CO2 concentration, the monitor displays temperature and relative humidity.
The SAN-0001 Pocket CO2 Monitor and Data Logger is shipped fully tested and calibrated and,
with proper use, will provide years of reliable service.
FEATURES
•Personal protection from high CO2 levels in enclosed areas
•Wearable design with built-in belt clip
•Stable, long-life NDIR sensor for CO2 detection
•Up to 12 hours of continuous monitoring on full charge
•Visual, audible and vibrating alarm levels (user-adjustable) for CO2 safety
•Green/Yellow/Red LEDs quickly show current indoor air quality
•CO2, temperature and relative humidity data logging
•Up to 65,520 time-stamped records in internal memory

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 [phone].
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. If the monitor does not pass the bump test, do not use it.
Contact CO2Meter support at [phone] or e-mail us at
[e-mail].

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 [phone] or e-mail us at [e-mail]
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 to
return to normal display.
Note: If the monitor is on and the screen is black, press any button to access the menu options.
1. Settings
The device is equipped with a 30 sample rate default setting, which has the function to set record
periods as shown below. Pre-set and default record periods are displayed, however to change
default alarms see as follows.
1. Press Menu once to select the record period.
2. Press Next to change the default setting.
3. Press Set to save and return to normal display.

2. Set Alarm Threshold
If the measured CO2 value exceeds the selected alarm threshold, an LED will flash, an audible
alarm will sound, and the monitor will vibrate. 3 alarm thresholds can be selected: a 5,000ppm
CO2 alarm, a 5,000ppm TWA CO2 alarm and a 30,000ppm (3%) STEL CO2 alarm, See Appendix A
to determine which alarm is best for your application.
4. Press Menu once to select the alarm function.
5. Press Next to change the alarm threshold.
6. Press Set to save and return to normal display.
3. Set Temperature Units
Select temperature scale °Centigrade or °Fahrenheit.
1. Press Menu 2 times to select temperature units.
2. Press Next to switch between °C or °F.
3. Press Set to save and return to normal display.
4. Calibration
The monitor should be calibrated at least annually and can be calibrated either atmospheric
(outdoor 400 PPM CO2) or Zero with 100% Nitrogen (2) 0% CO2.
Both calibrations require the unit to be powered on.
Zero calibration procedure – 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 0 ppm. Once stabilized, do steps 1-4 (See Below).
Ambient calibration procedure – Expose the unit to outdoor air until it’s stabilized (3-5 minutes).
Then do steps 1-4 (See below).

8
See more information on calibration in the Maintenance section of
this manual.
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 Ambient or N2.
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 SAN-0001 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.
5. 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.
6. 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

9
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 5 times to select Data Logging.
2. Press Next to select Export, Reset (clear all) Memory or Exit without changes.
3. Press Set to begin exporting data, to reset the memory, or to exit to the normal
display.
