	1095
	1096	Calculate scale factor：
	1097	Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	1098
	1099	Calculation formula：
	1100
	1101	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	1102
	1103	Actual calculations：
	1104
	1105	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
