Correlation Screen
A dashed cursor line shows the position of the largest peak (best result). The dashed cursor
line can be moved once the correlation has been stopped, by using the arrow keys. Moving
the dashed cursor line alters the correlation distance.
This screen shows the result of a correlation where the position of the leak is. In this example
63.4 metres from the Red Out Station and 60.6 metres from the Blue Out Station.
The time delay is calculated at 2.3 milliseconds.
The correlation shown has a SNR of 29:1. Signal to Noise Ratio (SNR) means the largest
correlation peak is 29x larger than any other displayed peak shown on the correlation graph.
Hence the larger the SNR the more pronounced the peak will be.
Press 1(Listen) Attach the headphones to the control unit before pressing 1. Use the arrow
keys to select the sensor required to listen to; BASE, RED, BLUE or YELLOW. The sound will
transmit in blocks of approx 20 seconds. To stop listening press ENTER, but note the sound
will continue until the 20 seconds elapses.
