[[Image:Reports_Tools_Ribbons_356.png]]: ''Fractional:'' '' Opens the properties dialog for the tachometers that derives from another one. Fractional tach. computes RPM speed for a non accessible shaft by using gear ratio setting.'' ''Adapted for gear boxes and transmissions. | |||
Note: the fractional tach. cannot be settled from the ''Vision'' interface, use the ASB for it. | |||
Used to define up to 4 fractional tachs using data from the tach or the Ext Tach. | |||
Virtual tachs computes RPM speed for a not accessible shaft by using gear ratio setting. | |||

* '''Label''': the name of the output tach. | |||
* '''Source''': the source of a virtual tach can be any tach or Ext. tach. | |||
* '''Tach ratio''': this is the ratio between the output angular speed and the input angular speed. This setting is defined by the product of 2 fractions: N1/D1 * N2/D2 where N1, D1, N2 and D2 are integer values. Tach.1 / Tach.2 ratio maximum value can be set up to 100. | |||

* '''Rotation:''' This setting defines the way the phase variation is counted: clockwise or counterclockwise for each tachometer. | |||
The rotation side is managed independently for each tachometer (Ext. sync, input, D, combined and fractional). Default setup is ''Counterclockwise''; | |||
See ''Ext Sync §'' for details | |||
* '''Average size''': defines the average number used to compute the average speed. Revolution number n average speed is: avrg_speed<nowiki>[</nowiki>n-1<nowiki>]</nowiki> <nowiki>+</nowiki> (inst_speed<nowiki>[</nowiki>n-1<nowiki>]</nowiki> - avrg_speed<nowiki>[</nowiki>n-1<nowiki>]</nowiki>) / avrg_size. | |||
* '''Max speed''': predefine a maximum angular speed to preset the scale and order tracking maxima. The limit of Max speed depends on the sampling frequency of the input signal and is equal to: 60 * Fe / (2 * 2.56) for the maximum. The Max speed setting is also used: | |||
* to specify the limit of Y axis of the RPM profile result | |||
* to compute the limit of the maximum order of the SOA plug-in analyzer. | |||
* '''Min speed''': defines the lowest measured angular speed. All revolutions with a speed lower than Min speed are forced to 0 RPM. By default Min speed is expressed in RPM. Min speed is automatically adjusted to Max speed/1000 but it is possible to go lower. | |||
