Thread Break Sensor Test
The thread break sensor test design is helpful to check the thread break sensor to make sure it is sensing
thread moving on the thread break sensor bar. The machine reports thread breaks if the thread break
sensors attached to the bar do not detect thread running against it when it should be. If there is a val-
id thread break, the Bravo OS should report a thread break (no thread running against the sensor bar).
Conversely, if there are no thread breaks, there should be no thread break reports. Cut the thread where
it runs into the needle a few times to see if valid thread breaks are detected properly. There should be no
thread breaks or pull outs other than those that you initiated deliberately for testing purposes. Also, there
should be no inconsistency in the fill portion of the design.
The thread break test should be sewn on one layer of white broad cloth or equivalent with one layer of 2
oz. cut-away backing.
Thread Break Test
The thread break test design is helpful to check for thread breaks by running several different stitch
lengths and types in several directions. There should be no thread breaks, pull-outs, or long tails when
sewing this design.
The thread break test should be sewn on one layer of white broad cloth or equivalent with one layer of 2
oz. cut-away backing.
