B . Sound Velocity 



The sound velocity meter Is Initially calibrated In the laboratory. Field 

 calibration checks are impossible; however, malfunctioning can be detected by 

 checking the free-running effect with the sensor in air, which should be approxi- 

 mately 2800 cycles per second, as compared to 3000-3500 cycles per second with 

 the sensor submerged . 



C . Depth 



Vlbrotron depth gage calibrations are similar to those of the sound velocity 

 meter. In that calibrations are made prior to field operations. Depth calibrations 

 are made with a dead weight tester, while the ship is dockslde with ship motion at a
