Quick answer: Specify shaft viewing direction, positive rotation and sensor sign on the test diagram. Report resisting and driving torque consistently.

How can opposite torque readings be prevented in supplier reports?
Sign confusion can turn a valid measured curve into an apparent disagreement. A plot without a viewing datum is especially weak when two drums rotate. Include units and explain whether the sensor records applied torque or spring-delivered torque.

A practical verification method
Use a known rotation and a marked reference direction to verify the sign before collecting the batch results.
| Item | What to record | Purpose |
|---|---|---|
| Reference configuration | Part or assembly identity and drawing revision | Make comparisons traceable |
| Test conditions | Relevant position, direction and operating condition | Compare the same characteristic |
| Decision evidence | Use a known rotation and a marked reference direction to verify the sign before collecting the batch results. | Resolve the specific question before approval |

Use the result in an engineering request
Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
