The further away the scale is mounted from the centre line
of the workpiece, the greater is the potential for linear error.
Linear Error Compensation is expressed as a multiplier,
which is displayed for each axis when LIN COMP is
selected. A factor of 1.000000 indicates no compensation.
True or standard distance moved
The compensation factor is:
Measured distance
A gauge block, standard bar or laser measurement should
be used as the standard against which the displayed
movement is compared.
ZERO
Move the machine to the zero position
of the standard against which the axis is
being compared and zero the axis with
the zero key. Move the machine a
known distance as determined by the
standard and enter that value.
The new compensation factor is auto-
matically calculated and displayed.

IMPORTANT:
All measurements will be adjusted according to
the compensation factor entered for each axis.
To disable the adjustment, enter a Linear Error
Compensation factor of one (1.000000).
