How should I place my ear-clip?
An ear-clip is designed to be attached to the earlobe. Place it on your earlobe so that it sits securely and comfortably. You may have to remove your earring if needed for secure placement. If you have a visible hole in your earlobe, make sure it is not right in the center of the clip where a light emitter is situated. If you have troubles with placing the clip on your earlobe, you can comfortably place it on a finger tip. Make sure that you are in a relaxed sitting position during the measurement process. Try to limit abrupt body movements. Simply follow the intuitive instructions when running each test.
