* Near a whole number (g = 1.95, 2.0, 2.05), setting that whole number is correct on both sides; setting the lower whole number fails as soon as the gap exceeds it | * Near a whole number (g = 1.95, 2.0, 2.05), setting that whole number is correct on both sides; setting the lower whole number fails as soon as the gap exceeds it | ||
* In post-processing, when the ''Tach'' option of Signal Op. is used, check that the ''Missing teeth'' value of the created tachometer (''Tachometer > Ext. tach. 1'') is the same as the Tors one. | * In post-processing, when the ''Tach'' option of Signal Op. is used, check that the ''Missing teeth'' value of the created tachometer (''Tachometer > Ext. tach. 1'') is the same as the Tors one. | ||
*It is recommended to set the instrumentation in order to limit the number of missing pulse below 3s''': Indeed long interval without pulses will lead to a strong order 1 artefact in the instantaneous speed signal due to interpolation of sample. Remaining below 3s for the missing pulse provide correct measurements. | |||
