A height gauge is a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on.

It used in metalworking or metrology to set or measure vertical distances and also it measures the height of an object.

Using veriner, and dial calipers, measure the dimensions of your part. Procedures for using veriner caliper Check that the vernier caliper correctly reads zero when the jaws are closed.Close the jaws around the object but do not over tighten. When both locking screws are tightened the caliper can be removed from the object and read without worrying if the jaws will shift position.You can read the main scale . Note the number of divisions on the Vernier plate from its zero mark to a line which exactly coincides with a line on the fixed bar.Procedures for using Dial caliper The same as veriner caliper except using dial indicator for reading divisions rather than veriner scale.ProcedureResults
