On acquisition mode, you need to activate a DC input on the frond tend, then activate the tach option | On acquisition mode, you need to activate a DC input on the frond tend, then activate the tach option | ||
Tach: On / Off. Used to activate a tachometer with an RPM level proportional to the DC level | '''Tach:''' On / Off. Used to activate a tachometer with an RPM level proportional to the DC level | ||
Rotation: Depending on the way you look at a measured shaft or on the convention you are using, the shaft may be considered as rotating clock wise or counter clock wise. This has noticeable impact on the phase of spectra and orders. | Rotation: Depending on the way you look at a measured shaft or on the convention you are using, the shaft may be considered as rotating clock wise or counter clock wise.

Average size: defines the average number used to compute the average speed. Revolution number n average speed is: avrg_speed[n-1] + (inst_speed[n-1] - avrg_speed[n-1]) / avrg_size. | '''Average size:''' defines the average number used to compute the average speed.

Max speed: defines the highest measured angular speed. speed higher than Max speed are rejected. By default Max speed is expressed in RPM. | '''Max speed:''' defines the highest measured angular speed. speed higher than Max speed are rejected. By default Max speed is expressed in RPM. | ||
