Yes, this was briefly addressed but it deserves a closer and more specific look. Chances are if you are not familiar with scales, you looked across the term “tare” with some sort of confusion. Fear not, because it is truly a simple feature. But, because so many models have it (if not every single one) it is important for you to fully understand what it is. Outside of being able to reset the scale back to zero, the tare function allows you to calculate the weight of the individual contents in your bag.
Here is an example, before you put anything in your luggage weigh your bag. Once you get that weight, you can set it as your tare. After that, fill your bag with all the contents you plan on taking with you to the airport. Once you weigh that, the scale will calculate this weight subtracted by your original weight. Thus, you get the weight of the contents inside.
