    Operation and Installation DL850 270 kHz Chapter: 5. Calibration procedure SKIPPER Electronics AS Step 1. Heading error correction: The vessel sails a steady course in calm waters and the user reads the resultant angle (averaged drift). This is entered into the system using the Head err button and encoder on menu 3, and adjusted until the averaged drift angle is zero.

    SKIPPER Electronics AS NAUT rules The DL850 will, by default, measure the “speed through water” (STW) from doppler effect in water particles in a distance 1 to 15 meters away from sensor. This is depending of depth as area will decrease to avoid bottom signal in shallow water.
