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 Set AN/GSM-287 or AN/GSM-705. 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 parenthesis.
5. Accessories Required. The accessories listed in table 3 are issued as indicated in
paragraph 4 above, and are used in this calibration procedure. Whenever necessary, these
items may be substituted by equivalent items, unless specifically prohibited.
