Measurement in accordance to ISO 17713-1. The starting threshold will be determined by measuring the lowest wind speed at which the cups of the anemometer start to continuously turn and the anemometer is producing a measurable output...

Wind tunnel measurements of starting threshold of wind vanes are performed in accordance to the ASTM D 5366 – 96. The starting threshold is determined by measuring the lowest speed at which the vane is moving from a 10° deflection to a...

The procedure for the calibration of tilt response is in accordance to IEC 61400-50-1:2022, previously IEC 61400-12-1:2017 . The wind sensor is slowly tilted between -30° and 30° at a fixed wind speed of approx. 8 m/s and fixed yaw...

During a Wind Direction calibration in accordance to the IEC 61400-50-1:2022, previously IEC 61400-12-1:2017 , the wind sensor is slowly yawed for a whole revolution and back at a fixed flow speed of approx. 8 m/s and a fixed tilt angle...
