OPERATION
Note:
LCD backlight will turn off automatically after 5 seconds of inactivity.
When LCD backlight is off, press either button to turn on the backlight. It will not turn
the monitor off or change the °C/°F setting.
1. Power button
1.1 When the Monitor is turned off, press to turn on the unit.
1.2 When the Monitor is turned on, press for 3 seconds to turn off the unit.
When the unit is first turned on, it performs 5 seconds countdown for Monitor warm up, then
enters normal display with current CO2, temperature, and humidity readings displayed. The
monitor starts taking measurements when power on and updates readings every 2 seconds.
The device can’t shut off alarm, if power off will come back in alarm mode and must delay.
2. Temperature Units Switching Button
2.1 Temperature Unit
Press shortly to switch two temperature units: °F and °C.

3. Calibration
There are two calibration methods: Ambient Air (300-600ppm) and Nitrogen (0-200ppm).
By pressing the temperature unit switching button for 5 seconds, the monitor will enter CO2
calibration mode. While in calibration mode, press the temperature unit button quickly to
switch between AIR (Ambient Air Calibration) or N2 (Nitrogen Calibration). Select NO to exit
without calibration and press the power button to confirm.
4. Alarm Threshold
There are 2 fixed alarm thresholds: 5,000 ppm CO2 (low alarm) and 3% CO2 (Short Term Exposure
Limit) (high alarm). The alarm thresholds can be changed dependent on the user, to L0.5 (5000
ppm), L0.5T (5000 ppm TWA), L1.0 (10000 ppm), L1.5 (15000 ppm), and L3.0 (30000 ppm).
If the measured CO2 value exceeds the define Low Alarm threshold, the alarm LED will flash red
at 2Hz and the audio alarm “de de … de de …” will sound. If the CO2 level exceeds the High
Alarm threshold, the LED will flash faster and the audio alarm will increase. To alert users in a
noisy environment, the monitor will also vibrate.
5. Automatic Atmospheric Pressure Compensation
The displayed CO2 level is affected by atmospheric pressure or change in altitude. To
insure maximum accuracy, this monitor has automatic atmospheric pressure compensation
for CO2 concentrations by means of a digital atmospheric pressure sensor integrated in
the unit. No calculations or maintenance is required.
6. Man down alarm
Falling by breathing dangerous gases can cause serious injury and even fatality to workers. If the
Man down alarm function in SAN-10 is set on, SAN-10 can detect falls and send a man down
alert which will activate the audible and visual alarms and alert other people in the area.
The man-down detection uses a three-axis accelerometer to automatically monitor the user’s
movements. If a sudden fall/impact is followed by a lack of movement for 6 seconds, the alarm
will sound. Turn off the alarm by pressing either of the two buttons.

7. Reset Button
Users can reset the unit by pushing a reset button through a
hole on back of shell.
MAINTENANCE
Calibration
The SAN-10 comes pre-calibrated from the factory. However, the CO2 sensor should be calibrated
at least once a year, or as described in your company’s safety procedures. You can perform the
calibration yourself, or you can return it to CO2Meter for factory calibration at a nominal fee.
CO2 can be zero and/or atmospherically calibrated. Zero calibration requires 100% nitrogen (0%
CO2) calibration gas, a flow regulator and flexible tubing. These can easily be obtained online:
https://www.co2meter.com/collections/accessories/products/demand-flow-regulator
The Atmospheric calibration will not require additional materials but must be performed in
outdoor (300-600ppm fresh air) during the entire procedure.
The temperature and humidity sensors do not require calibration and should remain accurate for
the life of your unit.
Cleaning and Storage
The front cover and case can be cleaned with a mild solution of detergent and water. Apply
sparingly with a soft cloth and allow to dry completely before using. Do not use aromatic
hydrocarbons or chlorinated solvents for cleaning.

RECOMMENDED CO2 LEVELS AND GUIDELINES
• 250-350 ppm: normal outdoor ambient concentrations
• 600 ppm: minimal air quality complaints
• 600-1000 ppm: less clearly interpreted
• 1000 ppm: indicates inadequate ventilation; complaints such as headaches, fatigue, and
eye/throat irritation will be more widespread. 1000 ppm should be used as an upper limit
for indoor levels.
ASHRAE Standard 62-1989: 1000ppm
CO2 concentration in occupied building should not exceed 1000ppm.
Building bulletin 101 (BB101): 1500ppm
UK standards for schools say that CO2 at averaged over the whole day (i.e. 9am to 3.30pm) should
not exceed 1500ppm.
OSHA:5000ppm
Time weighted average over five 8-hour work days should not exceed 5000ppm.
Germany, Japan, Australia, UK: 5000ppm
8 hours weighted average in occupational exposure limit is 5000ppm.
