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-286; AN/GSM-287; or AN/GSM-440. 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. Where the four-to-one ratio

cannot be met, the actual accuracy of the equipment selected 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.
