Tool range and target points;Repeated readings;Direction and adapter setup;Calibration date and handling history
Why this matters
Tool value depends on the question it can answer safely, the vehicles and systems it truly supports, and the repeatability of the result.
Evidence to capture first
- Inspect the wrench
- Exercise it as the manufacturer directs
- Test several points across the useful range
- Record repeatability and send out-of-tolerance tools for service
A disciplined path
- A homemade lever test is educational but not a substitute for traceable calibration on safety-critical work.
