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 displaywith current CO2, temperature,andhumidity 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 5seconds, the unit enters into Menu
status. There are six menu items by pressing the temperature unit switching button shortly to
loop switching between AIR, N2, Hx.x, Lx.x, A ON/AOFF, SC, Px, Log and E(exit). The menu
items are described in the following table.
Menu Items
Functional Description
AIR (“ ”)
“AIR” means Ambient Air Calibration. User presses the power button
to implement Ambient Air Calibration (300~600ppm).

3. Alarm Threshold
There are high and low alarm thresholds in SAN-11. Both high and low alarm has five thresholds:
5000 ppm, 5000 ppm TWA, 1.0%, 1.5%, and 3.0%. Obviously, high alarm threshold should not
less than low threshold. They can be same alarm level.
The SAN-11 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.
4. Automatic Atmospheric Pressure Compensation
The CO2 measurement is affected by atmospheric pressure or altitude changing. When users are
at high altitude, compensation should be madeto assure 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.

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-11 is set on, SAN-11 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 canturn off the currentman-down alarm by pressing anyone of the two buttons.
6. Reset Button
Users can reset the unit by pushing a reset button through a hole on back of shell.
MAINTENANCE
Calibration
The SAN-11 comes pre-calibrated from the factory. However, the O2 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 GasLab 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.

Windows reports
“unknown device” error
Go to Gaslab.com, select the App Notes tab, and follow the
instructions for
AN153: Troubleshooting Software Driver Installation (PDF).
Slow response
The log file stored in the monitor is very large. The monitor needs
time to transfer data to your computer.
Readings do not change
Confirm the monitor is correctly connected to the computer. Make
