The anemometer consists of three parabolic cones fixed at 120 degree to each other to form the sensing part. The concave surfaces of the empty cups all face one direction. How do we use it? What should you pay attention to during instrument maintenance?

1. How to use anemometer
1. Before using the meter, check whether the meter pointer points to zero. If there is an offset, you can gently adjust the meter's mechanical adjustment screw to bring the pointer to zero.

2. Place the calibration switch in the off position.

3. Insert the measuring rod plug into the socket, place the measuring rod vertically upward, tighten the screw plug to seal the probe, and then perform the "correction" switch to the "full position." Slowly adjust the "full adjustment knob" to point the meter pointer to the full position.

4. Set the "calibration switch" to the "zero position" and slowly adjust the "coarse adjustment" and "fine adjustment" knobs to make the meter pointer point to the zero position.

5. After completing the above steps, gently pull the screw plug to expose the probe (the length can be selected according to your needs), so that the red dot on the probe faces the wind direction. Check the calibration curve against the meter reading to find the measured wind speed.

6. After measuring several points (about 10 minutes), the above steps 3 and 4 must be repeated to normalize the meter current.

7. After testing, the "correction switch" should be placed in the off position.

1. It is prohibited to use anemometer in flammable gas environment.

2. Do not place the anemometer probe in flammable gas, otherwise it may cause fire or even explosion.

3. Please use the anemometer correctly according to the requirements of the instruction manual. Improper use may result in electric shock, fire and sensor damage.

4. During use, if the anemometer emits a strange smell, sound or smoke, or if liquid flows into the anemometer, please turn off the battery immediately. Otherwise, there is a risk of electric shock, fire and damage to the anemometer.

5. Do not expose the probe and anemometer body to rain. Otherwise electric shock, fire and personal injury may result.

6. Do not touch the internal sensor part of the probe.

7. If the anemometer is not used for a long time, please remove the built-in battery. Otherwise, the battery may leak and the anemometer may be damaged.

8. Do not place the anemometer in places with high temperature, high humidity, dust and direct sunlight. Failure to do so may result in damage to internal components or reduced anemometer performance.

9. Do not wipe the anemometer with volatile liquids. Failure to do so may cause deformation and discoloration of the anemometer housing. When there are stains on the surface of the anemometer, please wipe it with a soft cloth and mild detergent.

10. Do not drop or press the anemometer. Otherwise, the anemometer may malfunction or be damaged.

11. Do not touch the sensor part of the probe while the anemometer is charging. Otherwise, the measurement results will be affected or the internal circuit of the anemometer will be damaged.
