Before a callout or purchase

Take the observation with you.

Keep what you saw, what you actually checked and what remains unknown together. These tools produce a record you can review, copy or save. They do not identify a failed part.

Which tool comes first?

  1. If the fault is still unexplained, use the check-result guides, then make a service note.
  2. If a part has been proposed, ask for the test result and exact catalog match before reviewing the order.
  3. Compare repair and replacement only when the repair scope and both complete prices are available.

Your record stays under your control
