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-287 or 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, the
actual accuracy of the equipment is shown in parenthesis.
5. Accessories Required. The
accessories required for the
calibration are common usage
accessories, issued as indicated in paragraph 4 above, and are not listed in this calibration
procedure.
