882 -
883 -
884 -Test the current values at the depth of different liquids and convert them to a linear scale.
885 -Replace its ratio with the ratio of water to current in the decoder.
886 -
887 -**Example:**
888 -
889 -Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
890 -
891 -**Calculate scale factor：**
892 -Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
893 -
894 -**Calculation formula：**
895 -
896 -Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
897 -
898 -**Actual calculations：**
899 -
900 -Use this formula to calculate the value corresponding to the current at a depth of 1.5 meters: (6.918-5.035)/1.86470588235294+0.51=1.519810726
