[English | 简体] Bar Check Test
If a portable , battery-operated echo sounder is to be affixed to the side or bottom of the work boat to detect the water depth or seabed profile , the echo sounding result must be calibrated after the set up by a bar check test to determine its accuracy . The test is simply conducted by a diver to measure the vertical distance of the seabed from the echo sounder by the use of a steel measuring tape with a plumb or heavy weight at the end , to determine the actual depth and fine tune the echo sounder readings to eliminate its discrepancy .
