【Instructions for use】
1.Select the reference surface for measurement, adjust the height of the indicator and rotate the dial to zero before use, and then fix it by hex wrench;
2.Measure the corresponding positions on the diesel engine. For measuring valve protrusion, refer to the black scale on the dial. For measuring cylinder sleeve height, counter bore depth, etc., refer to the red scale on the dial (Note: the 0.1'' graduation can be read based on the number of clockwise rotations on the small dial);
3.If there are fixed limit values, adjust the two limiting buckles to the upper and lower limits for quick detection.
