EQUIPMENT REQUIREMENTS
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-287 or AN/GSM-440 and Secondary Reference Calibration
Standards Set, NSN 4931-00-621-7878. Alternate items may be used by the calibrating
activity when the equipment listed in table 2 is not available. 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. Where
the four-to-one ratio cannot be met, the four-to-one accuracy of the equipment selected is
shown in parentheses.
5. Accessories Required. The accessories required for this calibration are common
usage accessories, issued as indicated in paragraph 4 above, and are not listed in this
calibration procedure.
