MIL-PRF-38793C
g. If the note and footnote in FIGURE 2 are to be used in all procedures (see 3.2.3.1.5).
h. If instructions, drawings, and schematics for fabrication of jigs and test fixtures are to be
included in text or an appendix (see 3.2.4.3).
i. If the calibration procedures is to be automated or manual (see 3.2.8).
j. If performance of inspections is to be other than as specified in this document (see 4.1).
k. Packaging requirements (see 5.1).
6.3 Technical manuals. The requirement for technical manuals should be considered when this
specification is applied on a contract. If technical manuals are required, specifications and
standards that have been cleared and listed in DOD 5010.12-L, Acquisition Management
Systems and Data Requirements Control List (AMSDL) must be listed on a separate Contract
Data Requirements List (DD Form 1423), which is included as an exhibit to the contract. The
technical manuals must be acquired under separate contract line item in the contract.
6.4 Definitions. To clarify the terms used throughout this specification, the following
definitions are given:
6.4.1 Calibration equipment. Calibration equipment is equipment, other than the test
instrument, required to perform the calibration.
6.4.2 Functional check (test). A functional check is performed to verify correct functioning of a
test instrument or some feature of a test instrument which is independent of the accuracy of the
test instrument. The requirement is usually a condition to be met, rather than comparison with
numerical tolerance limit values. (Examples of functional checks are: oscilloscope position
control range and centering, multi-meter battery check, and oscilloscope sweep time vernier
range check).
6.4.3 Minimum use specification. Minimum use specifications are the principal characteristics,
accuracy, range, input impedance, and any other pertinent factors which are required during the
performance of the tests and measurements described in the procedure. This information is
intended to assist in the selection of suitable alternate equipment, which may be used if the
equipment listed in column 3 of the calibration equipment table is not available, or at the
discretion of the using laboratory. Satisfactory performance of alternate items will be verified by
the calibration technician prior to use. All applicable equipment must bear evidence of current
calibration (see 3.2.3.1.2).
6.4.4 Peculiar accessories. Peculiar accessories are those items furnished with a test instrument
and only used with that test instrument, but not physically part of it. For example, a high voltage
plug-in probe that is used specifically to extend the range of a particular voltmeter (see 3.2.2.3).
6.4.5 Test accuracy ratio. The TAR is the maximum allowable error of the unit to be measured
or calibrated, divided by the maximum known error of the measuring or generating device used
to perform the measurement. For example, if it is required that a system or equipment output
