INTRODUCTION
Congratulations on your purchase of this CO2Meter SAN-30 Personal Safety CO Monitor.
CO2Meter SAN-30 is a personal safety CO monitor designed to monitor ambient concentrations
of carbon monoxide (CO) in real time. CO gas poisoning is the most common type of fatal
poisoning in the world. SAN-30 is shipped fully tested and factory calibrated and, with proper use,
will provide years of reliable service.
FEATURES
 Electrochemical sensor, no consumable parts.
 Calibration methods: 0 ppm and 50 ppm
 Automatic atmospheric pressure compensation for CO concentrations
 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 – 10+ days per charge
 Man down alarm - leveraging accelerometer technology
APPLICATIONS
 Heating and Ventilation.CO is produced by oxygen-starved combustion in improperly
ventilated fuel-burning appliances such as oil and gas furnaces, gas water heaters, gas ovens,
gas or kerosene space heaters, fire places and wood stoves.
 Internal Combustion Indoors.CO is produced by all internal combustion engines. This
makes the SAN-100 useful in garages, car parks, venues, repair facilities or job sites where
cars, trucks or machinery is run indoors.
 Fire Fighters.CO is produced naturally in trace amounts by the partial oxidation of methane
in the atmosphere, volcanoes and forest fires.
Please take a moment to read these instructions before use. They will provide you with
all the necessary information for the correct use of your oxygen monitor.

THEORY OF OPERATION
The SAN-30 Personal Safety CO Monitor uses an electrochemical sensor to determine the
concentration of carbon monoxide in air samples. Air reaches the sensor by diffusing through the
openings on the back of the unit. Normal air movement is enough to carry the sample to the
sensor.

OPERATION
1. Power button
1) When the Monitor is turned off, press to turn on the unit.
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 CO, temperature, and humidity readings displayed. The monitor starts
taking measurements when power on and updates readings every 2 seconds.
2. Temperature Units Switching Button
2.1 Temperature Unit
Press shortly to switch two temperature units: °F and °C.
2.2 Menu Status
By pressing the temperature unit switching button for 5 seconds, the unit enters into Menu
status. There are three menu items by pressing the temperature unit switching button shortly
to loop switching between 0, 50, A ON/AOFF and E (exit). The menu items are described in the
following table.
Menu Items Functional Description
0 “0” means 0 ppm Calibration. User presses the power button to
implement 0 ppm Calibration
50 “50” means 50 ppm Calibration. User presses the power button to
implement 50 ppm Calibration
A ON/ AOFF
Setting Man down alarm function on/off. User presses the power
button to switch “A ON” (allowing Man down alarm) or “AOFF”
(prohibiting Man down alarm).
E User presses the power button to exit the menu status.

3. Alarm Threshold
The SAN-30 is equipped with audible, visual and vibration alarms to alert you when the ambient
oxygen concentration exceeds either of the two factory preset alarm levels:
 Low CO Alarm: 35 ppm - LED will flash and audible alarm will sound 3x / sec.
 High CO Alarm: 200 ppm - LED will flash and audible alarm will sound 2x / sec.
To alert users in noise environment, an inner vibrator will vibrate at 1Hz in both CO Alarm.
ATTENTION! - If a Warning or Danger alarm is triggered
while using the instrument as a safety monitor, leave
the area and seek fresh air immediately. Remaining on
site under such circumstances can cause serious
impairment or even lead to death.
4. Automatic Atmospheric Pressure Compensation
The CO measurement is affected by atmospheric pressure or altitude changing. When users are
at high altitude, compensation should be made to assure maximum monitor accuracy.
This device has automatic atmospheric pressure compensation for CO concentrations by means
of a built-in barometric pressure sensor.
5. 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-30 is set on, SAN-30 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/impact and a lack of movement for a period of 6
seconds.
Once alert, people can turn off the current man-down alarm by pressing any one of the two
buttons.

6. Reset Button
Users can reset the unit by pushing a reset button through a hole on back of shell.
CO SENSOR CROSS-SENSITIVITY
Electrochemical sensors are cross-sensitive to specific gases other than the target gas of interest.
While cross-sensitivities are limited as much as possible by sensor design, some interactions still
exist. The table below shows the most common cross-sensitivities.
Gas Gas Concentration Sensitivity % of SAN-30
H2 900ppm <2%
CI2 10ppm <0.5%
SO2 20ppm <0.5%
NO2 10ppm <0.5%
NO 50ppm <3%
C2H4 400ppm <35%
NH3 20ppm <0.1%
If the meter is exposed to one of the above gases, it will clear itself if you expose it to normal
outdoor air for 30 minutes. Do not expose the device to the fumes of inorganic solvents (e.g.,
paint fumes) or organic solvents.
MAINTENANCE
Calibration
The SAN-30 comes pre-calibrated from the factory. However, the CO 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.

The temperature and humidity sensors do not require calibration and should remain accurate for
the life of your unit.
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.
