10. Now rotate protractor and again position stylus at zero point A as described in 5 and 6
above, ensuring that the position of the cartridge in the slots alongside is not changed but only
rotated for alignment of the cantilever in zero point A. (Fig.17)

Fig.17 Rotation at A

11. Recheck alignment of the cantilever at zero point B. If cantilever is not aligned here,
rotate protractor to find where on line “x- y” the cantilever is aligned again. (Fig.18&15)

Fig. 18   Alongside line “X-Y” alignment at B

If the stylus is still in front of zero point B on the line “x-y” as before, but nearer to point B,
then  again  pull  cartridge  slightly  forward  for  distance  “S”  and  repeat  the  whole  process  by
aligning at zero point A until the stylus will be at zero point B.
If  stylus  end  up  behind  the  zero  point  B  on  line  “x-y”  then  move  cartridge  in  opposite
direction to before, backwards and realign it at zero point A.
If  stylus  is  still  behind  the  B  point,  the  cartridge  should  be  pushed  back  and  realign  at  zero
point A and realigned again at zero point B.
12. Continue until the stylus is in alignment at both points.

REMEMBER STEPS:

a)  Put stylus at zero point A and by rotation align cantilever along XY line.
b)  Align cantilever along XY line at zero point B by rotating protractor and see where stylus
is on the line XY- in front or behind zero point B.
c)  Move  cartridge  along  (not  rotating  it)  for  the  same  distance  as  stylus  is  overhanging  zero
point B for the same distance to increase the overhang.
d) Repeating these steps (a,b,c,a,b,c,…) will ensure that stylus& cantilever are in alignment at
both zero points A&B.

NOTE: Ensure that cantilever is not twisted due to bias force.
