The recalibrate option will only appear if the bottle is connected to the app. The bottle should always have the lid on and straw attached (if applicable) during the empty and full state for proper recalibration.
- First, completely empty your bottle and set it upright on a flat surface
- Open the HidrateSpark app on your device and navigate to the 'Bottles' tab located in the bottom menu.
- Once you're in the 'Bottles' tab, tap on the right arrow next to your bottle's name. This action will bring you to the 'Bottle Details' page.
- On the 'Bottle Details' page, scroll down until you locate the 'Recalibrate' option in the menu.
- Tap on the 'Recalibrate' option to begin the recalibration process for your bottle.
- Once finished, place your bottle on a flat stable surface. After 10-20 seconds, drink normally.
Note: The sensor has to be recalibrated anytime after it's removed from the bottle, including after charging, cleaning, etc. for accurate readings to record.
Recalibration requires the bottle to be filled up completely (to the threads) and sit for 10 seconds to set the max level on the sensor (17, 21, 24, or 32 oz.) Overfilling (water above the threads) or not filling the bottle completely, will cause miscalculation. e.g. if you only filled the bottle halfway (example 10 oz.) the sensor will think it is a full bottle and will likely then double the amount of water, thinking that 10 oz. is actually 20 oz.
