845	845	Test the current values at the depth of different liquids and convert them to a linear scale.
846	846	Replace its ratio with the ratio of water to current in the decoder.

	848	+**Example:**
848	848
	850	+Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	851	+
	852	+**Calculate scale factor：**
	853	+Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294

	855	+**Calculation formula：**
	856	+
	857	+Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
