The procedures may vary according to survey requirements and are intended only as a guide It is assumed that the operator is familiar with the various controls and their associated functions as detailed in the preceding sections of this manual 3 1 Things to Consider When Calibrating Calibrate daily in an area that is calm avoid any rocking of the vessel Never use rope or material that might stretch on your calibration bar Calibration of the DESO350 can be for both frequencies at once Perform calibration using the shallowest and deepest depths from your area If you do not have a velocimeter to compute the speed of sound start with the default speed of the unit 5000 feet or 1500 meters per second or the speed from the previous day The echo sounder is calibrated using draft index and speed of sound Measure the draft using a survey tape measure Apply index for the shallow calibration Apply speed of sound changes for the deeper depths If the water depth is less than 20 feet 6 meters As long as your unit is in the average speed of sound range use only the measured draft and index for calibration In other words the speed of sound will have little effect 10 If the water depth ranges from 0 5 to 60 feet 18 meters build a calibration bar that can reach the deepest part of the survey 11 For depths that exceed 60 feet use a bar that can reach as deep as possible In areas such as these we recommend that you use a velocime
10. d Actual depth from water surface to the bottom rsp v Average velocity of sound in the water column t Elapsed time measured from the transducer to the bottom rsp bar and back to the transducer k Index constant k Time equivalent to the index constant K dr Distance from the referenced water surface to the transducer draught Once the k value is determined it will not change until either the sounder or the transducer is changed The Index parameter should be adjusted to make the measured draught and the calculated draught equal Since the accuracy of measuring the depth depends on the value used for the velocity of sound in water along with the other factors shown above it is important that a realistic value for sound velocity is used In water velocity is a function of temperature salinity and pressure Therefore the sound velocity in one area may vary from the sound velocity measured in another area This means that whichever type of echo sounder is used it must be calibrated in order to provide the most accurate depth data at a given location Fig 3 1 Bar Check Parameters illustrated Qsij i ww J1043 g012bt b056 The most common calibration technique is the Bar Check method This method when employed properly has the advantage of determining the sound velocity draught and index value When this method of calibration is used acoustic sound waves are bounced off a suspended target
