NOTE

Minimum use specifications are the principal parameters required for performance of the

calibration, and are included to assist in the selection of alternate equipment, which maybe

used at the discretion of the calibrating activity. Satisfactory performance of alternate

items shall be verified prior to use. All applicable equipment must bear evidence of current

calibration.
