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. 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 parenthesis.

5. Accessories Required. The accessories required for the calibration are common usage

accessories, issued as indicated in paragraph 4 above, and are not listed in this calibration

procedure. The following peculiar accessories are also required for the calibration:

Semiconductor Device (coaxial crystal detector), Hewlett-Packard, Model 423AOPT03.
