1 Indications in parenthesis are for models with 45 degree range.
(12) Remove gage block stack and TI from sine plate.
a. Performance Check
(1) If not already done, setup equipment as shown in figure 2.
(2) Ensure TI is parallel to vertical face of angle plate.
TI must be secured to
prevent movement.
(3) Beginning with index table set to a 0 degree starting point, slowly rotate index
table toward and then past first corresponding value in table 5. If TI indication is not
within limits specified in first row of table 5, perform b below.
(4) Repeat technique of (3) above for remaining value in table 5. If TI indication is
not within limits specified in table 5, perform b below.

11. Over Range (Alternate Method)
a. Performance Check
(1) If not already done, setup equipment as shown in figure 1.
(2) Use precision level to level sine plate length and width to within 10 arc-sec.
