HL 6000 PC Correlator Operating Instructions

Doc No. R12244

Jan/2009

3.1.15 Measurement Statistics

First the curve shape for the correlation performed is analyzed and is allocated a quality factor

between 0 and 100. The higher the value, the clearer the correlation.
For low values, the button for frequency analysis (14) is shown in the statistics window because

an improvement might be possible by altering the filter settings.

Result statistics are also displayed.

With a measurement process that lasts longer, other louder noises (for example, water being

briefly extracted) can affect the correlation and this will result in the cursor (and thereby the

distance to the leak) not staying constantly in one position. These values appear in the statistics

with low percentage values. This way, the function helps you to better identify the position of the

leak.
