Manual Chapter 5

6-23

Note

CSI does not recommend using only three readings if four are

available.

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.
