The table may contain up to 32 pairs of these slope correction factors. Note that the Kc
factor, unlike these slope correction factors, is entered as a signed percent change in rate,
while these factors are simply rate multipliers. As points are entered, the point editor will
provide list access to the already entered points plus access to the [New Point] menu cell,
used to add a new point. The table may be created in its entirety and then activated by
selecting [Yes] in the [Table Active] menu cell. The entire table may be cleared by selecting
[Yes] in the [Clear Table] menu cell.
Note
Careless use of the calibration tables can have a detrimental impact on the measurement
performance of the flow meter.
Note
Take precautions before enabling these calibration tables. Although it is unlikely that all three
tables would ever be employed in a real installation, three tables are offered for maximum
user flexibility. Since the tables can be disabled without being destroyed, 2 or 3 optimization
strategies may be tested by this means in order to determine which approach is most
effective.
