INTRODUCTION
Congratulations on your purchase of the SAN-10 Personal CO2 Monitor and Data Logger. It is
designed to alert employees who work in enclosed areas where carbon dioxide buildup may
cause personal harm. If CO2 buildup occurs, it will show the level on screen, flash, alarm and
vibrate. In addition the SAN-10 includes built-in data logging and a man-down alarm that uses
an accelerometer to set off the alarm if a sudden shock to the unit (like the wearer falling down)
occurs.
The SAN-10 uses a non-dispersive infrared CO2 sensor to provide long term stability. It is
shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
FEATURES
•Audible, visual strobe and vibrating alarms
•Large LCD display
•Rugged design with protective rubber enclosure
•Heavy duty metal clip
•Front facing sensor unit
•Rechargeable Battery 4.2v, 1500mAh
•Micro USB cable and Wall USB charger
•Rechargeable Li-Ion battery – 20+ hours per charge
•Man down alarm - leveraging accelerometer technology
•Dual calibration methods: Ambient Air (300-600ppm) and Nitrogen (0-200ppm)
•Automatic atmospheric pressure compensation for CO2 concentrations
•No over-exposure or negative memory effects
•Stable NDIR sensor for CO2detection.
•CO2, and alarm!log data logging with time stamping
•Up to 149,500 time-stamped records in internal memory. Data can be exported via!

3.0 Alarm Threshold
The SAN-10 is equipped with audible, visual and vibration alarms to alert users when the
ambient oxygen concentration exceeds either of the two factory preset alarm levels:
•Danger High Alarm: LED will flash and audible alarm will sound 3x / sec.
•Warning Low Alarm: LED will flash and audible alarm will sound 2x / sec.

There are high and low alarm thresholds in the SAN-10. Both high and low alarms have
five thresholds: 5000ppm, 5000ppm TWA, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5% and
4.0%. Obviously, the high alarm threshold should not be less than the low threshold.
They can be the same alarm level.

6
Automatic Atmospheric Pressure Compensation
The CO2 measurement is affected by atmospheric pressure or altitude changing. When
users are at high altitude, compensation is made internally to ensure maximum monitor
accuracy.
This device has automatic atmospheric pressure compensation for CO2 concentrations by
means of a digital atmospheric pressure sensor integrated in the unit.
Man Down Alarm
Falling by breathing dangerous gases can cause serious injury and even fatality to workers.
If the Man downalarm function in SAN-10is 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 in order to identify a sudden fall or impact and a lack of movement for a period of
6 seconds.
Once alerted, you can turn off the man-down alarm by pressing either of the two buttons.
Reset Button
Users can reset the unit by pushing a reset button through a hole on back of shell.

CALIBRATION
Step 1. Power the unit on by pressing and holding the power button for 3 seconds
Step 2. Press and hold the ºF/ºC button for 5-10 seconds to open the first menu
Step 3. Use the ºF/ºC button to scroll through the first menu which will read:
a) AIR (Ambient Air Calibration Option)
b) N2 (Zero Nitrogen Calibration Option)
c) L 0.5 (Low alarm threshold)
d) H 3.0 (High alarm threshold)
e) A ON (Alarm option. Turns the alarm on and off)
f) E (To exit the menu and return to home screen)
Step 4. Perform AIR or N2 calibration
“AIR” Ambient air calibration
•Follow above instructions to
access the menu
•The “AIR” option is the first to
appear
•Bring the unit OUTSIDE or use
400ppm CO2
•Press the power button to start
the calibration
•If the screen reads “FAIL” repeat
until the calibration passes
*IF THE MONITOR DOES NOT READ IN
THE 300-600 PPM RANGE BEFORE
PERFORMING THE CALIBRATION, IT
WILL NOT CALIBRATE IN THE FIRST
MENU.
“N2” Nitrogen calibration
•Follow above instructions to
access the menu
•Go to “N2” option
•Expose the device to nitrogen gas
•Press the power button to start
the calibration
•If the screen reads “FAIL”
repeat until the calibration
passes
*IF THE MONITOR DOES NOT READ
IN THE 0-200 PPM RANGE IT WILL
NOT CALIBRATE IN THE FIRST
MENU.
Step 5. (USE ONLY IF THE DEVICE IS NOT IN RANGE AND FAILED TO CALIBRATE IN
THE FIRST MENU)
To open the second menu press and hold the ºF/ºC button while already in the first menu.
Step 6. This menu will allow you to calibrate without range limitations. The second menu will
read:
o-AIR (Ambient Air Calibration Option without limits)
o-N2 (Zero Nitrogen Calibration Option without limits)
oE(To exit the menu and return to home screen)
Step 7. When calibration is complete make sure the unit is reading within the span
values. You can test with fresh air which should read about 400ppm CO2.

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 itfor factory calibration at a nominal
fee.
Cleaning and Storage
Apply sparingly with a soft cloth and allow drying completely before using. Do not use
soap or Alcohol cleaning. Do not use aromatic hydrocarbons or chlorinated solvents for
cleaning.
