'Rank' is a two character code with associated wording that Herguth uses to
define the state of the sample (and therefore the unit). Any Rank starting with 'O' means OK, 'A' means Abnormal, and 'C' means Critical. The second character further defines the rank as follows:
AB= ABNORMAL: Abnormal test results are present.
AE= ABNORMAL: Abnormal results are indicated for equipment condition. Oil appears satisfactory.
AL= ABNORMAL: Oil sample data has significant anomalies that will require action and or further investigation at the next scheduled service interval.
AM= ABNORMAL: Machine sample data has significant anomalies that will require action and or further investigation at the next scheduled service interval.
AN= ABNORMAL: Oil and machine sample data has significant anomalies that will require action and or further investigation at the next scheduled service interval.
AO= ABNORMAL: Abnormal results for oil are present. Equipment appears satisfactory.
AX= (Abnormal - no comments)
CA= CRITICAL: Critical equipment condition exists, as well as abnormal oil results.
CB= CRITICAL: Critical oil conditions exist, as well as abnormal equipment results.
CE= CRITICAL: Critical equipment condition exists. Oil appears to be satisfactory.
CM= CRITICAL: Sample data indicates a serious and immediate problem exists.
CO= CRITICAL: Oil sample data indicates a serious and immediate problem exists.
CR= CRITICAL: Sample data indicates a serious condition exists.
CX= (Critical - no comments)
NX= (Not Ranked - no comments)
OK= NORMAL: Sample data is satisfactory. No action is required at this time.
OM= MONITOR: Data for machine and/or fluid condition should be noted and monitored.
OR= STATUS: Test results for refrigerant are satisfactory.
