|English term or phrase: meter spread settings|
|To increase spread, increase the knockmeter reading to 80 or more by adjusting the fine spread dial clockwise and then reduce the knockmeter reading to 50 ± 3 by adjusting the fine meter reading dial counterclockwise.|
spread, n—in knock measurement, the sensitivity of the analog detonation meter expressed in knockmeter divisions per octane number.
Digital Detonation Meter Spread and Time Constant Settings—Experience has shown that these variables can be left constant, and default values can be used. the default value for Spread on the Digital Detonation Meter can be left at 0, and the default value for Time Constant on the Digital Detonation Meter can be left at 38.
Analog Detonation Meter Spread and Time Constant Settings—Optimize these variables to maximize spread commensurate with reasonable K.I. signal stability.
To increase spread, increase the knockmeter reading to 80 or more by adjusting the fine spread dial clockwise and then reduce the knockmeter reading to 50 ± 3 by adjusting the fine meter reading dial counterclockwise.
A126.96.36.199 To decrease spread, decrease the knockmeter reading to 20 or less by adjusting the fine spread dial counterclockwise and then increase the knockmeter reading to 50 ± 3 by adjusting the fine meter reading dial clockwise.
A188.8.131.52 If at any point during the spread adjustment procedure, adequate range of adjustment is not possible using the fine controls, the coarse dial for that function should be moved so that proper range is available using the fine dial.
|ajuste do fator do medidor|
ajuste do fator (de sensibilidade) do medidor.
em se tratando de um componente passivo (o medidor), não há a ganho de corrente ou tensão.
Spread pode ser entendido como fator de sensibilidade, ou seja, conta-se quantas divisões há na leitura do medidor, e depois divide este valor pelo fator de sensibilidade, obtendo o número de octano:
numero de divisões / fator = número de octano
um procedimento normalmente feito para leituras de multímetros/galvanômetros analógicos.
