1. wind speed and current computing relationship
For example, the range is 0~30m/s, the analog output is 4~20mA current signal, wind speed and current 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 current output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated current value. The list of commonly used values is as follows:
| current(mA) | wind speedValue (m/s) | Calculation Process |
| 4 | 0.0 | (30-0)*(4-4)÷(20-4)+0 |
| 5 | 1.9 | (30-0)*(5-4)÷(20-4)+0 |
| 6 | 3.8 | (30-0)*(6-4)÷(20-4)+0 |
| 7 | 5.6 | (30-0)*(7-4)÷(20-4)+0 |
| 8 | 7.5 | (30-0)*(8-4)÷(20-4)+0 |
| 9 | 9.4 | (30-0)*(9-4)÷(20-4)+0 |

| 15 | 20.6 | (30-0)*(15-4)÷(20-4)+0 |
| 16 | 22.5 | (30-0)*(16-4)÷(20-4)+0 |
| 17 | 24.4 | (30-0)*(17-4)÷(20-4)+0 |
| 18 | 26.3 | (30-0)*(18-4)÷(20-4)+0 |
| 19 | 28.1 | (30-0)*(19-4)÷(20-4)+0 |
| 20 | 30.0 | (30-0)*(20-4)÷(20-4)+0 |

2. conductivity and current computing relationship
For example, the range is 0~360°, the analog output is 4~20mA current signal, conductivity and current 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 current output range upper limit, B1 is the lower limit, X is the currently read conductivity value, and C is the calculated current value.
