Setting Up The Unit
The scale travel is broken down into as many as 200 user-defined segments, each with their
own correction factor, measured against a high-accuracy standard. The following parameters
need to be identified:
Each Correction Point is measured with respect to the Starting Point - zero - which is usually
set close to one end of the scale. The Reference Point can be set anywhere along the scale,
and does not need to coincide with either the absolute datum or any of the correction points.
However, it may be convenient to make the absolute datum and the reference point the
same.
Always approach the Starting Point, Correction Points and Reference Point from the same
direction. If you do not, then the size of the tool or probe will render the measurement
inaccurate.
