How should users use the anemometer and operating procedures
An anemometer is an instrument that measures air velocity. There are many types of it, and the wind cup anemometer is commonly used in meteorological stations. It consists of three parabolic cone empty cups fixed on the bracket at 120° to each other to form the sensing part. The concave surfaces of the empty cups are all in one direction. The whole induction part is installed on a vertical rotating shaft, and under the action of wind force, the wind cup rotates around the shaft at a speed proportional to the wind speed. How should users use anemometer products? The following is a detailed description for you:
1. Before use, observe whether the pointer of the meter points to the zero point. If there is any deviation, you can gently adjust the mechanical adjustment screw of the meter to make the pointer return to the zero point; 2. Put the correction switch in the off position
3. Insert the plug of the measuring rod into the socket, place the measuring rod vertically upward, press the screw plug tightly to seal the probe, put the "calibration switch" at the full position, slowly adjust the "full scale adjustment" knob, so that the meter pointer points to in the full position;
4. Set the "calibration switch" to the "zero position", and slowly adjust the two knobs of "coarse adjustment" and "fine adjustment" so that the pointer of the ammeter points to the zero position
5. After the above steps, gently pull the screw plug to expose the probe of the measuring rod (the length can be selected according to the needs), and make the red point on the probe face the wind direction. According to the reading of the electric meter, check the calibration curve. Find out the measured wind speed;
6. After measuring for several minutes (about 10 minutes), the above steps 3 and 4 must be repeated once to standardize the current in the meter
7. After the measurement, the "calibration switch" should be placed in the off position.
