If you're taking an inventory count with the Bluetooth scale, and come across a volume-based item that doesn't have a full weight, you can add it on the fly.
All you'll need is an unopened unit of that item to get the full weight.
Note: If you don't have an unopened unit at that time, you can use the Visual mode until you're able to add a full weight.
Adding a Full Weight
To add a full weight to an item, follow these steps:
With the item called up, tap the "Scale" tab
Tap "Weight Full" on the prompt
Put an unopened unit of the item on the scale
Tap "Add Full Item Weight"
The added weight displays under "Full weight". You can then place a partial item of that type on the scale to get an accurate measurement.
