  • Page 4 = Sets the decimal point position within the measured value POINT POS The Kalesto radar sensor measures the distance from the bottom of its housing* to the water surface: the maximum measured value is 30.00 m. The measurement result for distance or level measurement is scaled by entering a value in the 0 % and 100 % boxes in field 15 of the OTT-LOG operating matrix.
  • Page 5 16 and 18. – For a resolution in 0.01 ft: Use 98.43 instead of 30.00 (30 m = 98.43 ft) * For distance measurements: possible using OTT-LOG version V2.16 and later versions (100 % value, 0 % value: max. ±29.999 m)
  • Page 6 Special input card for OTT-LOG necessary: 55.505.138.3.2 Min. surface velocity v = 1 m/s The actual velocity of the river is larger than the measured velocity of the KALESTO: v = v / cos a Kalesto For this reason it is necessary to enter a correction value in the 100 % field of the matrix.
