	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

	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
