## Discrepancy

WHILE COMPLYING WITH AD, 3.5 MINIMUM VACUUM COULD NOT BE OBTAINED, EVEN AT SEA LEVEL.  TROUBLESHOOTING REVEALED VACUUM INDICATOR WAS 2-2 1/2 IN HG LOW AND REGULATOR HAD BEEN MIS-ADJUSTED.  INSTALLED NEW GAGE, WHICH WAS CALIBRATED,  AND RESET REGULATOR DOWN. STANDBY SYSTEM RETESTED, OK.
