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, the four-to-
one 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 calibration
procedure. When necessary, these items may be substituted by equivalent items, unless
specifically prohibited.
