7.
In the
Prove Run Setup
group, adjust the
Number of runs to average, Maximum
number of runs
and
Number of passes
per run,
as needed.
The
Number of runs to average
is the number of consecutive runs required that
meet the set prove criteria to complete a prove sequence. The
Maximum number
of runs
is how many times the sphere will launch to try to attempt a complete prove
sequence. In the example displayed in Step 7, if three consecutive runs out of five
do not meet the criteria, then the prove sequence is incomplete, or aborted.
The Number of runs to average is only enabled for Repeatability.
The
Number of passes per run
field is only enabled for Pulse Interpolation-
type provers.
8.
In the
Prove Run Setup
group, adjust the
Inactivity Timer
, as needed.
The
Inactivity Time
r entry specifies the maximum period of time, in seconds,
allowed to elapse between the prove events. If this period is exceeded before the
next event is expected, the flow computer aborts the prove operation, sets a "prove
failed" flag, and prints a prove abort report. The inactivity timer is reset after the
successful completion of each event during the prove sequence.
9.
In the
Prove Run Setup
group, adjust the
Run Acceptability
settings, as needed.
Run Repeatability
between runs is calculated either by comparing raw counts or
the calculated Meter Factor for the run, depending upon the configuration setup.
When the required number of runs has been completed, the Meter Factor is
calculated using either the average data method or the average Meter Factor
method, depending upon user configuration.
The ‘Prove in Progress’ status flag is then cleared, and the prove report is
generated.
Random Uncertainty complies with API MPMS CH. 4.8 and API MPMS CH. 13.1
and is the preferred method to accept prove runs. A minimum of three runs and a
maximum of 30 runs is required. The numerical requirement on random uncertainty
is 0.027% at a 95% confidence level. A custom report template is required in order
to print a prove report using Random Uncertainty.
