883 -
884 -
885 -Test the current values at the depth of different liquids and convert them to a linear scale.
886 -Replace its ratio with the ratio of water to current in the decoder.
887 -
888 -**Example:**
889 -
890 -Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
891 -
892 -**Calculate scale factor：**
893 -Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
894 -
895 -**Calculation formula：**
896 -
897 -Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
898 -
899 -**Actual calculations：**
900 -
901 -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
