4 Point Manual
The 4 Point Manual method is similar to the 4 Point Auto mode except that
the user has complete control over when data is acquired and which of the
four measurement positions it will be used in. This mode is useful when the
machinery is not mounted in a true horizontal orientation, so that the incli-
nometer is not effective, or when the clock positions relative to vertical and
horizontal base movements of the machine are nonstandard.
The current alignment method is always shown at the bottom center of the
screen. The alignment method is selected from the Alignment Setup menu
which is accessed using the Options key. Once the 4 point method is
shown, using the Up/Down Arrow keys to select and the Number keys on
the keypad to toggle the selection, set the Sample Rate.
Sample Rate – determines the number of data samples that are to be col-
lected and averaged together to produce a single Laser PSD reading. Use
the Left and Right Arrow keys to toggle sample rate from 1 to 25 samples.
The default is 2.
After the job has been defined and any soft foot condition corrected (if nec-
essary), select Alignment Data to acquire a set of shaft readings.
