1. wind speed and DC0-5Vvoltage computing relationship

  For example, the range is 0~30m/s, the analog output is 0~5V DC0-5Vvoltage signal, wind speed and DC0-5Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is DC0-5Vvoltage output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated DC0-5Vvoltage value. The list of commonly used values is as follows:

DC0-5Vvoltage(V)	wind speedValue (m/s)	Calculation Process
0	0.0	(30-0)*(0-0)÷(5-0)+0
1	6.0	(30-0)*(1-0)÷(5-0)+0
2	12.0	(30-0)*(2-0)÷(5-0)+0
3	18.0	(30-0)*(3-0)÷(5-0)+0
4	24.0	(30-0)*(4-0)÷(5-0)+0
5	30.0	(30-0)*(5-0)÷(5-0)+0

    As shown in the above formula, when measuring 2.5V, current DC0-5Vvoltage is 15m/s。

2. conductivity and DC0-5Vvoltage computing relationship

  For example, the range is 0~360°, the analog output is 0~5V DC0-5Vvoltage signal, conductivity and DC0-5Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is conductivity range upper limit, A1 is the lower limit of the range, B2 is DC0-5Vvoltage output range upper limit, B1 is the lower limit, X is the currently read conductivity value, and C is the calculated DC0-5Vvoltage value. The list of commonly used values is as follows:

DC0-5Vvoltage(V)	conductivityValue (°)	Calculation Process
0	0.0	(360-0)*(0-0)÷(5-0)+0
1	72.0	(360-0)*(1-0)÷(5-0)+0
2	144.0	(360-0)*(2-0)÷(5-0)+0
3	216.0	(360-0)*(3-0)÷(5-0)+0
4	288.0	(360-0)*(4-0)÷(5-0)+0
5	360.0	(360-0)*(5-0)÷(5-0)+0

    As shown in the above formula, when measuring 2.5V, current DC0-5Vvoltage is 180°。
