EQUIPMENT REQUIREMENTS
calibration procedure. This equipment is issued with Secondary Reference Calibration
Standards Set NSN 4931-00-621-7878. 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
between the standard and TI. Where the four-to-one ratio cannot be met, the actual
accuracy of the equipment selected is shown in parenthesis.
usage accessories issued as indicated in paragraph 4 above and are not listed in this
calibration procedure. The following peculiar accessory is also required for this calibration:
Three flexible extender cables supplied with TI and a locally procured 20 k Ω, 2 W,
5 percent resistor.
