For example 27.3 have tobe understood as 1027.3 kg/m 3 . To determine the milk density, write downthe result from the display and add 1000.Example: result 21,20; density = 1000 + 31,20 = 1031,2 kg/m 3** pH and conductivity measurements are optional and are delivered oncustomers' request.The abbreviated form of the density is used also when entering data forsamples in working mode Recalibrate, for example:If the measured sample density is 1034.5 kg/m3, then in the menu forentering the samples parameters used for calibration, across the parameterDen = , you have to enter 34.5.2.3.
