(3) Set the dial indicator to "0".  Place it on the mounting post of

the gaging arbor with the contact button touching the

indicator pad.  Force the dial indicator downward until the

needle has made a half turn clockwise.  Tighten down the

dial indicator in this position.

(4) Position the plunger on the gage plate.  Move the gaging

arbor slowly back and forth and locate the position at which

the dial indicator shows the greatest deflection. At this point,

once again set the dial indicator to "0".

Repeat the procedure to verify the "0" setting.

(5) After the ZERO setting is obtained, rotate the gaging arbor

until the dial indicator rod does not touch the gaging plate.

Record the number the dial indicator needle points to.
