1. Adjust the height of the "pressing wheel" according to the size of the workpiece to be measured, so that the "pressing wheel" can press the measured workpiece with an appropriate pressure.
2. Raise the "pressing wheel" through the "operation handle", place the tested workpiece on the "rotating work shaft", and then return the "pressing wheel" to its position.
3. Adjust the height of the “meter frame” and move it so that the dial indicator (diameter indicator) touches the surface of the workpiece to be measured, and adjust the dial pointer to zero.
4. Adjust the "lever meter" probe to the proper position of the workpiece to be measured, and make it contact the surface of the workpiece, and adjust the dial pointer to zero.
5. Rotate the hand wheel to fine-tune the meter head according to the actual situation to complete the reading.
