Tips: 4-20mA output signal conversion calculation for 3-cup anemometer.

When the 3-cup anemometer range is 0~30 m/s and the output is 4~20mA, if the output signal is 12mA, how to calculate the current wind speed value?

The span of this wind speed range is 30m/s, expressed by 16mA current signal,
30 m/s ÷ 16mA = 1.875/mA, that is, a current of 1mA represents a wind speed change of 1.875m/s.

The measured value is 12mA － 4mA = 8mA. 8mA*1.875m/s /mA = 15m/s. The current wind speed is 15m/s. The calculation formula is:

Wind speed = 1.875*current － 7.5, current value unit is mA.

how many times we need to calibrate the 3-cup anemometer?

I received this 3-cup anemometer, The anemometer is very high up and we cannot get the serial number from the unit. I am hoping you can give us how many times we need to calibrate the 3-cup anemometer.
