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 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 provide a four-to-one ratio between the

standard and TI.
