4.Rotational Speed Measurement
1) Stick the reflective paper on the object to be measured.
2)Fix the tachometer in a stable position or state, so that the laser emission and receiving window of thetachometer are50 to 500 mm away from the object to be measured.
3) Press the power/measurement button to startthe counting measurement, you can also press the laser buttonto enter the continuous measurement. Align the laser to the reflective paper on the measured object, the optimal measurement angle should be able to keep the measured value stable.
4) Start the device to be measured, and the tachometer will display the rotation speed of the measured object.Delivery
