EQUIPMENT REQUIREMENTS
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Sets AN/GSM-287, AN/GSM-705 or Secondary Reference Set NSN 4931-00-621-7878.
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-one ratio between the standard and TI.
Where 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
calibration procedure. The following peculiar accessory is also required for this calibration:
Crystal detector, Hewlett-Packard, Model 423AOPT03 (423AOPT03).
