SECTION II
EQUIPMENT REQUIREMENTS
4. Equipment
Required. Table 2 identifies the
specific equipment used in this
calibration procedure. This equipment is issued with Secondary Reference Standards
Calibration Set NSN 4931-00-621-7878 and is to be used in performing this procedure.
Alternate items may be used by the calibrating activity when the equipment listed in
table 2 is not
available. The
items selected must be
verified to
perform satisfactorily
prior to use and must bear evidence of current calibration. The equipment must meet or
exceed the minimum use specifications listed in table 2. The accuracies listed in table 2
provide a four-to-one ratio between the standard and TI
5. Accessories Required. The
accessories listed in
table 3 are
issued as
indicated in
paragraph 4 above and are to be
used in this
calibration procedure. When
necessary,
these items may be substituted by equivalent items unless specifically prohibited.
