ENGLISH
128 WITH MICROMETER HEAD ONLY
The desired range is obtained by using the extension rods
and rod points with the 2" (50mm) range micrometer
head (see Table 1). The necessary combination of rods
with the micrometer head are joined together by threaded
connections. They are brought to seat on hardened and
lapped faces with a firm, but not extreme amount of
pressure, to assure the accuracy of the seating.
Caution: A high degree of cleanliness must be
maintained between all mastering or mating faces
of end rods, extension rods, contact nibs, etc., when
performing adjustments, settings of calibration, in order
to preserve the measurement integrity of the system.
When the line of measurement is not predetermined,
the correct procedure in measuring with the inside
micrometer is to hold the non-micrometer head end in
contact with the piece to be measured. Then use the
micrometer head to sweep the other end of the surface
to be gaged to determine the point for final reading.
When the tool is used in a horizontal position, it should
be supported the full length by positioning the collars
in "V" grooves.
In maintaining the micrometer head accuracy, care in
handling and an occasional drop of light instrument
oil on the threads is sufficient. Adjustment for thread
wear is provided in a binding nut which is exposed
by backing off the thimble. Adjustment of individual
rods allow for wear of contact ends. A light coating
of preservative should be kept on the rods when not
in use. Repair of the tool should be undertaken by
qualified personnel or returned to the factory.

128 COMBINATION HEAD AND
MASTER USAGE INSTRUCTIONS
The 128 Combination Head and Master is designed
to be used with the 128 End Rods and Extension
Combinations as supplied in the 128 Inside Micrometer
Set. It combines the linear setting ability of a long
range micrometer with the ease of readability of a
precision dial indicator.
To be used, the combination head (indicator and
micrometer assembly) must be set to the exact
size specified on the setting master. To do so,
the micrometer is set at the 1" (25 mm) setting
(micrometer mid-range) and firmly locked.
The combination head is now properly placed in the
setting master and the entire assembly placed upright
such that the micrometer measuring end points upward.
The micrometer end of the combination head is now
swept or rocked in two directions (fore and aft as well
as from side to side) and slightly rotated to obtain a
MAXIMUM reading on the dial indicator. See Fig. 1.
The small hand of the indicator should read zero while
the large hand should read either zero, plus or minus
in accordance with the sense and magnitude of the
actual size marked on the setting master.
For example: A master marked 10.0005" (250mm)
should cause the indicator small hand to read zero
while the large hand should read PLUS .0005"
(.01mm). A master marked 9.9995 should cause the
indicator small hand to read zero while the large hand
should read MINUS .0005" (.01mm).

ENGLISH
Should a correction be required, a bezel locking screw
(accessible through a threaded plug in the side of the
housing) may be loosened and the indicator bezeled to
the correct reading.
It should be noted that the end result of the above
adjustment and/or settings is that a reading of zero by
both indicator hands and a 1.000" (25mm) micrometer
setting will correspond to an overall nominal length of
10.000" (250mm) for the 128 Combination Head.
The combination head may now be used with the proper
combination of micrometer setting, end and/or extension
rods to allow a minimum measurement capability of
11.00" (275mm) [with a 2" (50mm) rod] and a maximum
measurement capability of 83.000" (2100mm),
155.000" (3900mm) or 29.000" (7500mm) depending
of the #128 series inside micrometer set in use.
