SECTION II
EQUIPMENT REQUIREMENTS
Table 2 identifies the specific equipment to be used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-286. Alternate items may be used by the calibrating activity. 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 required for this calibration are common
usage accessories, issued as indicated in paragraph
above, and are not listed in this
calibration procedure.
