If you place an item on the Bluetooth scale and there is something inside, but the WISK app says it is empty, there are a few reasons why this may be the case:
The density of the liquid
Wrong item weight
Weighing a different item than what was scanned
Scale may not be on flat and level surface
If the item doesn't have an empty weight on file, WISK uses the full weight of the item and the density rating of the item's category to calculate how much liquid remains.
For some types of alcohol (mainly liqueurs), this density rating can vary.
Note: You can view densities on the Families & Categories page of the WISK Web Portal.
To get a more accurate measurement, you can add an empty weight to the item information.
With a full and empty weight on file, the density rating for the category is ignored.
If you have scanned an item that is almost empty, you can pour the contents out into another container, and record the empty weight of the item to get a more accurate measurement.
How to add an empty weight after scanning an item:
Tap "Empty Weights" under the item
Tap "Add weight"
Select the unit of measurement and enter the empty weight of the item. Tap "Done"
The empty weight is added. Tap the back arrow to return to the item
The empty weight displays under the item and you can re-weigh the partial item
Wrong Item Weight
It’s possible the full weight of the item on file may be inaccurate. Item weights can change over time due to redesigns in packaging.
If you have a full bottle of the item on hand, place it on the scale and compare it to the full weight on file. If there is a large variance, you can delete the inaccurate weight.
Note: It's possible to have more than one full weight on file. In that case, it uses an average of the full weights to calculate how much remains.
To add a new full bottle weight after scanning a bottle:
Tap the full weight that displays beneath the item
Swipe the incorrect full weight to the left and tap "Delete"
Tap Add Weight
Enter the full item weight in grams / kg / lbs / or Oz and tap "Done"
The full weight is added. Tap the back arrow to return to the item
The new full weight displays under the item and you can reweigh the partial item
Weighing the Wrong Item
Pay close attention to the volume of the item displaying in the app. For example, if you have called up a 1.75L bottle of Jameson, and you have placed a 750ml bottle on the scale, you won't get an accurate measurement.
This is most likely to occur when using the "List View" while taking inventory because you aren't scanning the item's barcode.
Always check the volume of the item that displays when entering your counts.
Whenever you're using the scale, make sure you're using these best practices:
the scale is on a flat and level surface
zero the scale (press the tare button if it displays anything other than 0g if nothing is on the scale)
