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, AN/GSM-287 and AN/GSM-705. 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. Where the four-to-one ratio
cannot be met, 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
