Prepare: Ensure 5 minutes of relaxation before taking measurement. Remove any jewelry or fingernail polish. When placing the oximeter on your finger, make sure your hand is warm, relaxed, and held below the level of the heart.
Measure
1. Install two AAA batteries into battery compartment correctly.
2. Insert one of your fingers into the finger chamber of the pulse oximeter.
Note: The fingernail should be facing the top chamber (which, contains the sensor). Finger should also be inserted completely into the chamber. Otherwise, measurement will be inaccurate.
3. Press the power-on button to turn on the pulse oximeter.
4. Finger and body should not tremble during measuring.
5. Read correct data from displayed screen.
Notes:
When your finger is inserted into the oximeter, your nail surface must be upward. The results may be wrong if you do not place your finger thoroughly in the oximeter.
Follow Through: Try to measure at the same time every day. If you notice any radical changes in your results make sure to report them to your doctor.
