Theory of Operation
The SAN-102 Oxygen Monitor uses an electrochemical sensor to determine the concentration
of oxygen 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
Plug the USB cable into the meter and a 120VAC wall adapter. It will take approximately 2
hours to receive a full charge. Once the meter is charged, it can run 4+ days before recharging.
Press the power button to turn on the meter.
When the meter is first turned on, it performs a 10 second countdown for device warm up, then
enters normal display with current oxygen level readings displayed. The device starts taking
measurements when powered on and updates readings every 3 seconds.
The OLED display will turn off automatically after 120 seconds of inactivity to conserve battery
power. However, the sensor will continue to monitor the O2 level. Briefly press the Power button
to view the display.
Hold down the Power button for 3 seconds to turn the meter off. This will conserve the battery’s
charge until you need to use the meter again.
