EQUIPMENT REQUIREMENTS
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.
items may be substituted by equivalent items unless specifically prohibited.
