4. Equipment Required. Table 2. identifies the specific equipment to be used in this
calibration procedure.
Standards Set AN/GSM-287. Alternate items may be used by the calibrating activity. The
item 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.
