EQUIPMENT REQUIREMENTS
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
standard and TI. Where the four-to-one ratio cannot be met, the four-to-one accuracy of the
equipment selected is shown in parenthesis.
