Description
F2 Pseudo Tach
Enable Pseudo Tach for time synchronous averaging or order tracking
intermediate shafts in gearboxes that cannot be accessed directly. Use the
Pseudo Tach to produce the turning speed signal. The analyzer uses the
following formula: (Incoming tachometer frequency) X ((tach frequency X
the number of teeth on the tached shaft)/number of teeth on the pseudo
shaft). Disable Pseudo Tach when you can use the tachometer directly on a
shaft. The default is Disabled.
F3 Tached Shaft
(Only available when Pseudo Tach is enabled.) If the reflective tape is on the
input shaft, enter the number of teeth on the tached shaft, which is the
shaft with the tachometer. The default is 1.
F4 Pseudo Shaft (Only available when Pseudo Tach is enabled.) Enter the number of teeth on
the internal shaft. The analyzer calculates the pseudo tach frequency based
on the number of teeth specified for the tached shaft and pseudo shaft.
The default is 1.
