The scale does not zero or weigh in the Merchant App and returns:

Error: Weighing scale. A different thread owns it.

Cause

The message means the scale timed out sending its reading back to the screen (a conflict over the scale reading). It is usually a local scale setting or session state on that station. When it shows up on several stations at the same time, it has lined up with a short backend issue that support cleared by restarting services.

Fix

  1. On a station where the scale works, note the scale settings (model, port, and unit of measure).
  2. Copy those settings onto the affected station in its station configuration.
  3. Restart the Merchant App on the affected station and test the scale.
  4. If several stations show the error at once, wait a moment and retry; if it does not clear, email support@shipstore.com.

What you should see

The scale zeroes and weighs with no thread-owner error, and a known test weight reads correctly.
