If two pressure values out of the three pressure values measured are less than the minimum values, do a check of the system to find the leak (Ref. TSM 32-44-00-810-808).
 NOTE : If the ambient temperature is more than 40 deg.C (104.00 deg.F)
____ and if two of the three pressure values measured are less than the minimum pressure values, do a second test. We recommend that you do the test at an ambient temperature near 20 deg.C (68.00 deg.F).
