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.
paragraph 4 above and are used in this calibration procedure. When necessary, these items
may be substituted by equivalent items unless specifically prohibited.
