Lowrance electronic LMF-200 manual Point Calibration, To execute 3-Point calibration

3-Point Calibration:

3-point calibration is designed for tanks that vary in shape from the top to the bottom. You can begin calibration at any point in the 3-point process, but we recommend starting calibration with an empty tank. In a 3-point calibration, you will set three points, one each for empty, half and full levels.

NOTE:

You DO NOT have to calibrate all three points to complete the calibration and you can calibrate the points (Empty Level, Half Level and Full Level) in any order you wish. Remember: Points that are not calibrated will not be as accurate as points that have been calibrated. For the greatest accuracy, we recommend all three points be calibrated.
