Troubleshooting methods and precautions for height ruler height gauge

A height ruler, also known as a height gauge, refers to the traditional vernier reading in this article, which has the following three common faults.

1. When the marking claw measuring surface is on the same plane as the base working surface, the "zero" and "tail" lines of the cursor do not coincide with the corresponding marking lines on the ruler body. You can loosen the vernier screw, adjust the appropriate position of the vernier to coincide with the corresponding engraved line on the ruler body, and then tighten the vernier screw when it meets the requirements.

2. When the measuring surface of the marking claw is on the same plane as the working surface of the base, the marking claw measures a larger gap. Make the marking claw measuring surface and the base working surface on the same plane, and then add a small amount of grinding powder to grind them together on the flat plate to meet the requirements.

3. The movement of the ruler frame is not good.

(1) Adjust the curvature of the frame spring appropriately.

(2) Adjust the depth of rotation of the adjusting screw and screw stop pin appropriately.

(3) Straighten the guiding surface and bottom surface of the ruler body.

If the above methods cannot eliminate the fault, send it back to the original factory for repair
