LEAK-DOWN TESTER REFERENCE-CHECK RECORD
Documentation aid only; follow current compatible tool and engine instructions. Compressed air can move an engine.
Job/engine/cylinder ID:
Tester make/model/ID and exact instruction revision:
Calibration/service-status evidence (or UNKNOWN):
Applicable engine preparation/positioning/safety procedure:
Hose/adapter IDs and applicable connection-check results:
Selected reading path (percentage scale / dual pressure / unresolved):
PERCENTAGE PATH
Prescribed reference condition and what was connected:
Expected reference mark; actual original indication:
Supported reference-check outcome and unresolved items:
DUAL-PRESSURE PATH
Prescribed input condition:
Original input pressure/unit; cylinder pressure/unit:
Exact manufacturer conversion chart/revision; derived leakage if applicable:
CYLINDER OBSERVATION
Operating condition; original reading/unit; capture reference:
Applicable comparison criterion/source; limits of comparison:
Repeat test: changed setup, original retained, new result separately:
Supported conclusion and next authorized check:
A zero entry alone does not prove calibration or the required operating reference. Do not substitute another tool's pressure, scale, chart or reference condition.
