SKF TKSA 31 & TKSA 41

3.6 Backlash

In order to achieve the best measurements accuracy,  

the measuring units should not be separated  
by more than 2° from each other.

When the MUs are more than 2° apart, this condition is called backlash.

Example: MUs are 3° apart in the above example

• 

Backlash warnings are enabled only when the MU are within a blue wedge.

• 

It is always possible to take a measurement with backlash (ie MU angle >2°).

 

- Accept the warning message to take the measurement anyway.
