Setting Up The Unit

Types of Machine Error

There are many types of machine error, including pitch, roll, yaw, flatness, straightness, and

Abbé error. The diagrams below demonstrate these errors.

Linear Error Compensation

In this mode, you can apply a single constant correction factor for each axis to all displayed

measurements. You calculate the correction factor, and specify it in parts per million (ppm).

In this mode a single constant correction factor for each axis is applied to all displayed

measurements.

As you follow the procedure you must ensure that you either use a stepped standard, and

approach each edge from the same direction; or if you must approach each edge from

opposite directions, then subtract the width of the tool or measuring probe from the value

displayed on the DP700.
