How to use a container with the scale
Edited
To use a container with the scale, a new "zero" level has to be set so the scale knows what the container weighs.
Place the empty container on top of the scale.
Click the left "setup" button.
Connect to the "Bottomless_Scale" Wi-Fi network on a device (phone/laptop/tablet/etc.).
Select "Set Zero Level" on the pop-up menu.
After keying in the registered email address, a confirmation email/text will be sent.
Store the product back in the container on the scale.
Tip: If the weight on the data page doesn't update immediately, don't worry — there might be a few hours delay. The re-zeroing process was successful if the confirmation email or text was received.
