1. Signal Level color Range Gain and palette Signal Level Display Dials ES3 Software 4 1 1 Range The dial at the bottom of the ES3 main display sets the maximum slant range for the system This is not the same as the maximum depth The Range is the maximum distance to which any beam can reach Since the ES3 is capable of up to a 120 swath the Range needs to be set to a higher number than the maximum depth value so that the outer beams will be able to detect the bottom A rule of thumb to set the correct maximum depth for the system is to set Range to twice the maximum anticipated water depth Note increasing the Range value will reduce the ping rate for the system due to the increase in travel time associated with the higher Range value 4 1 2 Gain The Gain dial sets the gain for the pre amplifiers inside the ES3 Head Setting the Gain correctly is critical to the proper operation of the ES3 If the gain is set to high the signal will saturate and will not give accurate depths If Q Page 14 of 37 S May 22 2006 CS Odom Hydrographic Systems Inc ES3 User Manual the Gain is set at too low a value there will be gaps in bottom detection In order to set the Gain correctly first make sure the signal window is open below figure Go to the Options menu on the ES3 software and confirm that the Signal Level block is checked A window should appear on the lower left hand corner of the ES3 control display The Gain is be2.
