The validity rule is an important concept in precision shaft alignment. It can be used to confirm that your readings are accurate and is why we don’t have to rotate a full 360 degrees in order to get accurate alignment information.
Here is a previous blog post with an embedded video that discusses dial indicator concepts including the validity rule.
Dial Indicator Concepts – TIR, The Validity Rule and True Position Sensing
To check the validity rule with your Fixturlaser Laser Shaft Alignment System:
1 – Sensors are mounted and rolled to the 12 o’clock position. A measurement is recorded which sets the S & M Detector values to zero (red boxes) as well as the angle values.
