EQUIPMENT REQUIREMENTS
calibration procedure. This equipment is issued with Secondary Reference Standards Set
NSN 4931-00-621-7878 and limited deployed to Secondary Transfer Calibration Standards
Set, AN/GSM-287 or AN/GSM-440. 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
between the standard and TI. Where the four-to-one ratio cannot be met, the four-to-one
accuracy will be listed, and the actual accuracy of the equipment selected is shown in
parentheses.
5. Accessories Required. The accessories required for this 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 this
calibration: Transponder test set kit, Teledyne Electronics, P/N 154397 (NSN 6625-01-118-
