NOTE
To calibrate a TI graduated in the metric system, it will be
necessary to convert the metric reading to applicable length in
inches. Formula is: 1 millimeter = 0.03937 inch, or 1 inch =
25.4 millimeters.
b. Adjustments. No adjustments can be made.
11. Length Measurement for Micrometer Calipers With Adjustable Mandrels and
Checking Standards
a. Performance Check
(1) Select appropriate gage blocks from gage blocks set to verify range of TI
length standards.
(2) Assemble gage blocks. Make certain that blocks are firmly wrung together prior
to applying tie rods. Each stack of blocks must have an inside caliper jaw at each end,
which serves as an end stop. See figure 3 below.
Figure 3. Gage Blocks - Equipment Setup.
(3) Set up length standard between end stops.
(4) After obtaining a satisfactory fix on end stops, total length of gage block stack
should not exceed the tolerance listed in table 6.
(5) Repeat (1) through (4) above for each length standard supplied with TI.
(6) Select longest adjustable mandrel supplied with TI and insert into TI frame
socket. Tighten knurled screw thumb tight.
