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 
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.
