EQUIPMENT REQUIREMENTS
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set 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
to-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.
may be substituted by equivalent items, unless specifically prohibited.
