DATE The date of the last rate table evaluation (YYDDMMHHMM)
LRATE Compensated leak rate in gph (negative number = a loss, no sign = a gain)
INTVL Total test duration, sum of all acceptable tests, in hours.
ST Status:
0 NO TEST - no evaluation.
1 PASS
2 FAIL
3 NOT USED.
4 INVALID - obsolete.
5 NO DATA:COUNT - not enough tests available to evaluate. There must be
at least 2 acceptable tests.
6 NO DATA:INTERVAL - not enough total test time to evaluate (< 6 hours).
7 NO DATA:RANGE - tests did not range over a sufficient time period.
test time < 10 hours AND tests date range < 5 DAYS.
8 WARNING INCREASE - excessive positive leak rate.
9 WARNING NEGATIVE_HOLD - 2 day waiting period before reporting a
failure.
AVLRTE Uncompensated Leak Rate, in gph (negative number = a loss, no sign = a gain)
VOL Average volume of all acceptable tests.
C1 Total number of tests in the rate table.
C3 Number of acceptable tests.
FDBK Feedback control variable, range 0 to 45 minutes.
ACPT Accept control variable, range 0 to 45 minutes.
THPUT Estimated monthly throughput in thousands of gallons.
EVAP If the Reid Vapor Pressure table has been entered, the evaporation rate will
be here.
RJT Of the last 20 tests completed, this is the number of tests rejected due
to excessive positive leak rate (>0.4 gph).
