Data Acquired at 9 O’clock (90°)
When all the data has been acquired all the desired points, press the Enter
key to accept the data. At this point the data is checked for validity (refer to
“Data Quality” on page 5-27 for more information). If the data validity is
satisfactory, you are returned to the main menu where the data may now
be viewed.
Otherwise, you are warned that a data validity error exists. At this point you
should either repeat the data acquisition to check for accuracy. This built-
in check helps alert you to the data losing reliability in the misalignment
calculations.
Note
For the greatest accuracy and repeatability, all readings should
be acquired using the same direction of rotation. In addition, it
is best to use the same direction of rotation as the machine nor-
mally operates.
