What do the different joint colors mean?

Joints are color-coded based on their JSI level:

  • Gray is < 0.8 JSI
  • Yellow is 0.8 – 0.89 JSI
  • Orange is 0.9 – 0.94
  • Red is > 0.95
I have an inspection that I don’t want to upload.

The default save location is C:\Program Files (x86)\Digital QC\data. Each folder inside this folder is an inspection. If you have several inspections queued, but don’t want to upload some of them, delete the job folders that you do not want to upload before submitting them in the software. The software will upload what it can, but the ones not uploaded will remain pending.

To clear the queue, there is a file in the folder called digqc.db.sqlite that contains all of the stored information regarding the software. By deleting this file, it will clear the inspection upload queue as well as reset all of the user settings. Deleting this file will void all inspections, so be sure to upload the good ones first.
