SECTION II

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, or 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. When the four-to-one ratio cannot be met, the

actual 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. When necessary, these items

may be substituted by equivalent items, unless specifically prohibited.
