Adjustment of the detonation meter to cause the knockmeter to read 50 ± 2 divisions, establishes the required numerical display of this standardized knock condition.

The intensity of combustion knock is measured by electronic detonation sensing and metering instrumentation.
Collect and have ready a calibrated compression pressure gauge assembly and the tools required to remove the detonation pickup and install the gauge assembly in the combustion chamber pickup hole.

Setting Standard Knock Intensity—O.N. ratings, regardless of octane level or barometric pressure, are presumed to be determined at approximately the same degree of knock, which is termed standard K.I.

Digital Detonation Meter
The analog detonation meter is adjusted to produce an analog knockmeter reading of 50 for these conditions.
knock and detonation = traduzir ambos por detonação?
