5.3.3 One point advice regarding noise table input procedure
It is necessary to provide some allowance around the echo peak and a margin of threshold for
noise amplitude. These are +-0.3m and +5dB respectively.
Noise Table point “n” must also be nearer than next Noise Table point “n+1”. If this rule is not
maintained, noise table errors will occur and this function will become invalid.
Also by using the PC configuration software, you can add or change the position of the noise
table with a right click.
1) On the “Tank Spectrum” tab, when the “START” button is clicked, you may view the red line
wave form data from the main unit as shown below.
2) If you would like to set the noise table manually, right click and select “ADD” at designated
points for the new table. Also the table (points) can be moved by a left-click and dragging.
3) After the noise table is set, click the “Noise Write” button to complete.
