X axis feed amount
(11) When you rotate the lens, the crosshairs will also turn accordingly. Now, read the X axis feed
amount on the scale.
This feed amount is the total feed amount. Eccentricity is expressed as 1/2 of the total feed
amount.
Eccentricity amount (
θ
) = Total feed amount / 2
Ex.: If the total feed amount is 12 ticks on the scale, the eccentricity is 6.
(12) Measure distance “A” between the lens you want to measure and the objective lens.
