EQUIPMENT REQUIREMENTS
this calibration procedure. This equipment is issued with Secondary Transfer
Calibration Standards Set AN/GSM-286. 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.
common usage accessories issued as indicated in paragraph 4 above and are not
listed in this calibration procedure.
