EQUIPMENT REQUIREMENTS
4. Equipment
Required. Table 2 identifies the
specific equipment used in this
calibration Procedure. This equipment is issued with secondary transfer standards
calibration set NSN 6695-00-621-7877, and 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
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
accuracy ratio between the standard and TI. Where the four-to-one ratio can not be met,
the actual accuracy of the equipment selected is shown in parenthesis.
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.
