TB 9-5210-210-50
NOTE
To calibrate TI which has a range greater than one-half inch,
verify one-half of range, then set TI to zero on the point at one-
half range and repeat check at each numbered division.
b. Adjustments. No adjustment can be made.
8. Repetition
a. Performance Check
(1) Set the dial indicator calibrator (A1) to obtain 25 percent of range indication on
the TI.
(2) Move the TI contact point a distance equal to approximately 20 percent of the
range of the TI away from the dial indicator calibrator plunger and allow contact point to
return gently to the plunger.
(3) Repeat (1) and (2) above at least five times. The maximum deviation between
the readings observed on the TI shall not exceed plus or minus one-fifth graduation.
(4) Repeat (1) through (3) above using 50 and 75 percent cardinal-numbered
divisions.
b. Adjustments. No adjustment can be made.
9. Final Procedure. In accordance with TM 38-750, annotate and affix DA Label 80 (US
Army Calibration System). When the TI cannot be adjusted within tolerance, annotate and
affix DA Form 2417 (Unserviceable or Limited Use) tag.
