Calculation method
Calculation method
Amount each reading lies below supplied range (mm)
max(0,minimum−reading), using exact decimal measurements.
Amount each reading lies above supplied range (mm)
max(0,reading−maximum).
Reference midpoint minus each reading, signed (mm)
(minimum+maximum)/2−reading, an arithmetic reference offset only.
Reading IDs outside supplied inclusive range
List readings below minimum or above maximum.
Symbols and units
- a
- Supplied gap measurements: cylinder ID, gap mm
- b
- Externally supplied comparison minimum gap (mm)
- c
- Externally supplied comparison maximum gap (mm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A supplied gap-measurement comparison, not a spark-plug adjustment instruction, compatibility check or service diagnosis. Manufacturer limits, measurement conditions and whether a plug can be adjusted are not inferred.
