The surface of the table could be scratched when sliding the work-
piece, thus affecting measuring accuracy.
Damage caused by hard particles.
Any hard particles lying underneath the workpiece may lead to inaccu-
rate measurements. Moreover, the surfaces of the measuring table and
of the workpiece may be damaged.
ü
The workpieces must have full contact with the measuring table.
—
Clean the measuring table before placing a workpiece or a clamping
device on it.
—
Always clamp the workpiece in such a way that it lies on the defined
points of support (three-point support). This can be achieved, for ex-
ample, by means of a clamping device.
