1.3 Preparing to Measure
Power-up
 Switch on the product. 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 "Initial power-up" on
page 19.
 Press the ENTER key to advance from the power-up screen to the
DRO.
If the product 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.
