The usage of the anemometer is as follows: 1. Before use, observe whether the ammeter pointer points to zero. If there is any deviation, gently adjust the mechanical adjustment screw of the ammeter to make the pointer return to zero; 2. Turn the calibration switch to the off position; 3. Insert the plug of the measuring rod into the socket, place the measuring rod vertically upward, press the plug to seal the probe, put the "correction switch" in the full-scale position, and slowly adjust the "full-scale adjustment" knob to make the pointer of the electric meter point to the full-scale position; 4. Turn the "calibration switch" to the "zero" position, and slowly adjust the "coarse adjustment" and "fine adjustment" knobs to make the pointer of the electric meter at the zero position. 5. After completing the above steps, gently pull the plug to expose the probe of the measuring rod (the length can be selected as required) and make the red dot on the probe face the wind direction. According to the reading of the electric meter, consult the calibration curve to find out the measured wind speed; 6. After measuring for a few minutes (about 10 minute), the above steps 3 and 4 must be repeated once to standardize the current in the instrument. 7. After measurement, turn the "calibration switch" to the off position.
Shenzhen Yukai Technology Co., Ltd. is an agent and sales company specializing in paint coating, nondestructive testing, construction road testing instruments, optical measuring instruments, power electrician testing instruments, environmental engineering testing instruments, nondestructive testing instruments and equipment, gas testing and other instruments. The prominent feature of NK3500 anemometer of this company is that it not only has comprehensive measurement parameters, but also is very convenient to operate, and all measurement operations can be completed by three buttons. Automatic shutdown after standby for 45 minutes, excellent waterproof performance, suitable for laboratory or field measurement. Detecting the changing trend of air pressure is an important content in meteorological monitoring. It can measure wind speed, temperature, humidity, dew point, altitude, air pressure and so on.
