Simple operation instructions:
M3 hand-held speedometer can be easily carried around, and the power supply of the radar is provided by a high-energy lithium battery pack
The oval button at the bottom of the M3 speedometer screen is "On / Off", press to enter the working state
The trigger at the handle of the speedometer is the speed-measuring key. When pressed, the radar will enter the normal working state and the speed can be measured.
When the trigger key is released, the speedometer will retain the last speed value.
Shutdown: Press the ellipse key at the bottom of the screen again.
Precautions:
If the radar and the measured wooden plaque are in one direction, the speed of the speed measurement is correct. Due to the angle problem during the actual speed measurement, the test error will occur. As the angle increases, the error also increases. This phenomenon is called the cosine effect.
So when measuring the speed of an object, try to keep it consistent with the moving path of the measured object or try to reduce the angle between the transmitted wave path and the moving object path. Make the measurement more accurate and stable!
