13. Verification
Quick-figure
The Quick-figure is used when verifying MAXICAL
®
III. The
meter’s highest resolution is defined as the Quick-figure. The
Quick-figure can be read in two ways:
1) In MAXICAL
®
III’s display
Select the next but last display - using the key on the left of
MAXICAL
®
III’s front panel. The measuring unit is displayed as
T-M, and the Quick-figure can be seen in the display for 8 min-
utes.
2) Data Output
Both the optical data output on the front of MAXICAL
®
III and
the data output on terminals 62-63-64 can be used for reading the
Quick-figure. Please refer to chapter 10.2.
Reseting the Quick-figure
It is not possible to reset the Quick-figure.
The Quick-figure is calculated to be the difference between the
Quick-figure before and after verification.
Quick-sum
When verifying ULTRAFLOW
®
II, Qn 1.5 m³/h, there will
normally be 10.000 pulses, corresponding to 10 energy integra-
tions or 100 litres. The total Quick-figure is of most interest in
connection with verifying.
13.1 Energy Calculation
The true energy - measured by MAXICAL
®
III during verification
must be calculated with greatest care as this value is the basis for
calculating the meter’s verification deviation. Energy can be
calculated as follows:
