EQUIPMENT REQUIREMENTS
NOTE
Minimum use specifications are the principal parameters required for performance of the
calibration, and are included to assist in the selection of alternate equipment, which may be used
at the discretion of the using laboratory. Satisfactory performance of alternate items shall be
verified prior to use. All applicable equipment must bear evidence of current calibration.
The instruments utilized in this procedure were selected from those known to be available at
Navy calibration facilities, and the listing by make or model number carries no implication of
preference, recommendation, or approval for use by other agencies. It is recognized that
equivalent equipment produced by other manufacturers may be capable of equally satisfactory
performance in this procedure.
