EQUIPMENT REQUIREMENTS
4. Equipment Required. Table 2 identifies the specific equipment to be used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Sets, AN/GSM-287 and AN/GSM-440 or Secondary Reference Set, NSN 4931-00-
621-7878. 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 provided a four-to-one ratio between the standard
and TI. Where the four-to-one ratio cannot be met, the actual accuracy of the equipment is
shown in parentheses.
5. Accessories Required. The accessories listed in table 3 are issued as indicated in
paragraph 4 above and are used in this calibration procedure. When necessary, these items
may be substituted by equivalent items, unless specifically prohibited.
