A leak-test exercise provides a calibrated electronic detector approved for the system refrigerant. A repeatable signal occurs at one joint after background checks. What does this support?
- AProof that every other joint is leak-free.
- BPermission to vent the entire charge.
- Further confirmation and repair planning at that suspected leak location.
- DA universal rule that all refrigerants require this detector.
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why C is correct
The localized repeatable signal identifies a suspected location under the stated test conditions. It neither certifies the whole system nor establishes a universal leak-test method.
