d. Fasten TI to dial indicator calibrator, as shown in figure 2, using adapters supplied
with TI and/or dial indicator calibrator.
NOTE
Each style of the TI requires that the TI be placed in a specific
position in the dial indicator calibrator prior to performing
calibration. Style A is connected as shown in figure 2; style B
must be connected with the dial face in a horizontal position.
Style C must be connected with the dial face in a horizontal
plane and contact point lever straight. During calibration of a
style C TI, the lever arm shall not deviate more that 15 degrees
from the horizontal plane of the TI. To ensure that the lever
arm does not deviate, the contact point lever must be
positioned horizontally at midrange to minimize any cosine
error.
