1. Tùy theo điều kiện cụ thể của vật thể quay cần thử nghiệm, chọn các đầu nối phù hợp, chẳng hạn như các khớp nối cao su.
2. Use the rotary range switch to select the appropriate range (turn the scale value to the same horizontal plane as the dial). If the unknown quantity is measured, the largest range should be selected for rough measurement, and then the range should be determined.
3. Let the test shaft of the tachometer contact the measured shaft, keep a certain pressure and operate synchronously, and keep it on the same centerline.
4. After the pointer of the tachometer is stable, the rotation speed of the measured rotating object can be measured. The speed is equal to the ratio of the upper limit of the range selected by the range switch to the full scale of the reading plate multiplied by the reading of the reading plate.
5. When measuring the linear velocity, a rotary test head should be used.
6. The measured readings are converted according to the following formula: linear velocity (m/min) = (upper limit of the range selected by the range switch/full range of the reading plate) tachometer circumference of the rotating wheel test head.
