Online measurement – Realtime correlation with 2 sensors
54
Use the following questions to assess the quality of the displayed correlation.
Question 1: Is the radio signal of both transmitters strong enough?
The radio symbol shows:
strong signal
The radio symbol shows:
weak signal
How to proceed:
Continue the
measurement and start a detailed
analysis.
Meaning:
continuous correlation hardly or
not possible
How to proceed:
x Move closer to the
Power transmitter in question
x Place the transmitter higher (e.g. on
a wall or on a traffic cone or similar)
x If necessary, place the transmitter at
an other measurement point
x If possible, there should be a direct
line of sight connection between
Correlator and transmitter
If still no connection can be made,
conduct an Offline measurement instead
of the Online measurement
Question 2: Is the correlation result reliable?
The curve shows one clear peak;
the lag value is green or yellow and
does not fluctuate
The curve shows no clear peak;
the lag value is red and fluctuating
Meaning:
the result is reasonable
How to proceed:
Continue the
measurement and start a detailed
analysis.
Meaning:
there is no leak or no accurate
localization is possible
How to proceed:
If you still suppose a leak
to be here, the following can help:
x Access the system settings menu,
adjust the „Averaging“ to “unlimited”
and restart the correlation.
