H2OPal makes a measurement every time it's set on a flat surface, so to ensure H2OPal always measures how much water you've drank there are two cases in particular that you need to pay attention to:
- After you fill up the bottle
If you have a drink right after filling up the H2OPal bottle and before you set it down somewhere, then H2OPal won't be able to detect that first drink you had after filling up the bottle. The way to get the most accurate results is to set the bottle on a table for five seconds or longer after you filled it up and before you have a drink.
The error due to having a small sip after you fill up the bottle probably won't have a considerable effect if you consider your entire daily goal, however, if you're really thirsty immediately after filling up the bottle it's good to keep this in mind.
- After you finish the bottle and it's empty
If you go to refill the bottle immediately after having the last drink, without setting it down on a table for at least five seconds, then the last drink you had can't be measured.
To ensure accurate results after using H2OPal for some time, or if you notice several unusual measurements, it may be useful to perform a recalibration. Here's an article on how to do that:
