✔ Your Biosense® can usually be used approximately 10 times before it needs to be charged. Then you will want to plug the unit into an energy source with the provided USB cable. You may want to charge it overnight regularly so you know it will be ready when you are.
✔ Make sure you do not have anything to eat or drink (besides water or black coffee) 1 hour prior to using Biosense® to protect the special sensor.
✔ When testing your ketones, take a regular breath in and then blow into the unit with the same force you would use to blow up a balloon until the end of the vibration.
✔ Don’t clean the mouthpiece with alcohol or any harsh chemicals. It may create false readings from the sensor.
✔ Don’t let the device sit in direct sunlight, overheat in high temperatures, or get exposed to rain or inclement weather.
✔ Don’t expect higher ketones immediately after waking up. Ketone production usually slows during sleep and rises as you become active.
