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 made to 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.
