Use the following questions to assess whether the leak position seems plausible or not.
Is one of the values
zero or close to zero?
If the answer is
NO
, the values seem plausible.
Continue the measurement and start a detailed analysis.
If the answer is
YES
, the leak is located precisely at the measuring point or outside the
correlated pipe section.
Cancel the measurement. Take the relevant transmitter and look for a new installation
point in order to enlarge the measuring length. Then start a new correlation.
Does each value
show the half of the measuring length
If the answer is
NO
, the values seem plausible.
Continue the measurement and start a detailed analysis.
If the answer is
YES
, the leak is located precisely half way between the measuring
points or a measuring error has occurred (so called ‘center point correlation’).
Cancel the measurement. Take one of the transmitters and look for a new installation
point in order to enlarge the measuring length. Then start a new correlation.
Use the various tools to analyze the displayed correlation:
•
When you tap the displayed correlation curve, the
Correlation analysis menu
with
the relevant tools opens.
•
When you tap the displayed coherence curve, the
Frequency analysis menu
with
the relevant tools opens.
Use the Back button
to return to the Correlation menu.
Some settings for calculating and presenting the correlation curve can be changed in
the in the System settings menu (see page 51).
