Page 3: Introduction
Underground Tunnels, Caves or Mines. Over time oxygen can be displaced by other naturally occurring gases like carbon dioxide, carbon monoxide, ammonia, methane and the oxidation of sulfides resulting in lower oxygen levels than is required for personal safety. Combustion in Confined Spaces. Combustion first uses up the available oxygen, then produces partial oxidation of carbon (carbon monoxide), hydrogen cyanide, and nitrogen oxides. Hydrogen gas can also be produced and displace oxygen. 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. Copyright © 2018-2019 GasLab.com. All Rights Reserved... -
Page 4: Theory Of Operation
Normal air movement is enough to carry the sample to the sensor. It has negligible cross sensitivity to other gases. The monitor benefits from low power operation while providing a much longer lifetime due to the non‐depleting sensing principle.

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 AIR, A ON/AOFF and E (exit). The menu items are described in the following table. Menu Items Functional Description “AIR” means Ambient Air Calibration. User presses the power button to AIR implement Ambient Air Calibration (20.90%). Setting Man down alarm function on/off. User presses the power button A ON/ AOFF 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.

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. 6. Automatic Atmospheric Pressure Compensation The O2 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 O2 concentrations by means of a built‐ in barometric pressure sensor. Copyright © 2018-2019 GasLab.com. All Rights Reserved... -
Page 7: Man Down Alarm
7. 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‐20 is set on, SAN‐20 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. 7. Reset Button Users can reset the unit by pushing a reset button through a hole on back of shell. MAINTENANCE Calibration The SAN‐20 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 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 to dry completely before using. Do not use soap or Alcohol cleaning. Do not use aromatic hydrocarbons or chlorinated solvents for cleaning. Copyright © 2018-2019 GasLab.com. All Rights Reserved... -
