Considerations
- Do not touch the fan blade with force.
- Do not store or operate the instrument in areas with high temperature or humidity.
- In use, do not let the strong light directly shine on the fan, in order to avoid measurement errors.
- Avoid violent vibration.
- Remove the battery before storing the instrument for a long time.
Operation
wind speed measurement:
- Press me button to turn on the power.
- Hold the anemometer and let the fan plane of the anemometer align vertically with the wind direction of the airflow for measurement.
- The display will show the wind speed, wind temperature and wind humidity at the same time.
Data hold:
To freeze a displayed reading, press the button(<1 Sec.). The “H” icon will
appear and the most recent reading will appear in the display. Press the
button(<1 Sec.) to exit the mode and return to normal mode.
Backlight on or off:
Press the button and hold it for more than 2 seconds to enable or disable the
backlight function.
MAX/MIN/AVG function:
Press the key (:51 Sec.) to turn on the maximum function, and then press the
key to cycle through the maximum, minimum and average values. Long the key
press (>1 Sec.) returns to normal measurement function.
Temperature unit selection:
Press the key to select the temperature unit.
Wind speed unit selection:
Press the key to select the desired wind speed unit (m/s, km/h, mill/h, ft/m,
ft/s, knots).
Auto shutdown function.
When the power is turned on, the automatic shutdown function is turned on by
default. No operation within 10 minutes will automatically shut down.
If you need to cancel the auto-off function, press and hold the key before
turning on the meter, then press the key to turn on the power, and then
