Power-up the ND 1200R
 Switch on the ND 1200R. The POWER switch is located on the rear
of the enclosure. After switching the power on, or after a power
failure, the power-up screen will be displayed. See "Switching on the
ND 1200R" on page 13.
 Press the FINISH key to advance from the power-up screen to the
DRO.
If your ND 1200R was configured to establish a machine zero upon
powering up, a message will be displayed asking you to cross
reference marks or specify axis references manually.
Establish machine zero
A repeatable machine zero is required for the DRO to apply the
calibration chart to the machine geometry correctly.
Usually the calibration is based on referencing via reference marks on
the encoders. To establish the machine zero after power-up:
 Move the stage to have the reference mark crossings recognized on
each axis.
If the machine zero is determined via hard stops:
 Move the stage to the hard-stop reference position and press
ENTER on each axis.
It is not recommended to use the machine without active
calibration. This would lead to unknown position errors.
