(2) Rotate the TI clockwise until knot of nylon string is on side of pulley opposite
weight and slightly below center of pulley. Observe indication on TI.
(3) Rotate the TI counterclockwise until knot of nylon string is again opposite
weight and slightly below center of pulley. Observe indication on TI.
(4) If the indications observed in (2) and (3) above are not the same, perform b
below.
b. Adjustment
(1) Remove the bezel and crystal assembly by prying gently.
(2) Repeat a(l) through (3) above and adjust position of index to obtain equal
indications in both directions (R).
9. Range
a. Performance Check
(1) Using weight and pulley combinations as specified in tables 4, 5, and 6 for
appropriate range of the TI, check the TI in both directions.
(2) Indications obtained on the TI should be within the tolerances specified in the
appropriate table.
b. Adjustment. If necessary prepare a correction chart for TI, delineating any
corrections to be applied to obtained readings.
