EQUIPMENT REQUIREMENTS
4. Equipment
Required. 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. When the four-to-one ratio cannot be met, the actual accuracy of the
equipment selected is shown in parenthesis.
5. Accessories Required. The
accessories required for this
calibration are common
usage accessories, issued as indicated in paragraph 4 above, and are not listed in this
Table 2. Minimum Specifications of
