■

 6.7.2 Cross cursor measurement (on B-H graph)   

 

①

 If          is rotated when Cross cursor is displayed, Cross cursor moves and the value of the point on the cursor is displayed 

 
on Cursor Values. 

 

② 

Pushing          allows the movement amount of the cursor to toggle between Coarse (movement in unit of 20 points) and   
 
Fine (movement in unit of 1 point). For Fine movement, "

Fine

" is displayed at the upper side on B-H graph.
