About

Army secondary-standard barometers at Anniston Army Depot, Anniston, Alabama. The instrument is larger in size and has greater accuracy than Barometer ML-512(*) used in fixed meteorological stations. The construction of Barometer MIL-330(*)/FM and Barometer ML-512(*), however, is almost identical. Page 21, paragraph 10. Delete subparagraph d and substitute : d. Scale Calibration Chart (fig. 9). A scale calibration correction chart, mounted in the lid of the wooden barometer case, represents the deviation of the instrument from the secondary-standard calibration equipment located at Anniston Army Depot at the time the instrument leaves the depot. This correction is determined for each individual instrument over the entire range and must be applied to each reading of the aneroid barometer. Page 22, paragraph 10. Delete subparagraph e and substitute: e. Carrying Case (fig. 8).
