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, a single constant correction factor is applied for each axis to all displayed measure-
ments. The correction factor is calculated, and specified 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 ensure that you approach each edge from opposite directions, then
subtract the width of the tool from the value displayed on the DP1200. The DP1200 Automatically takes
into account the probe diameter as per setting (Linear Only).
