Operation
1.1 Overview
The ND 120 is an advanced digital readout (DRO) system for
performing 2 or 3 axis measurements using TTL encoders. The
ND 120 can be used with optical comparators, toolmaker’s
microscopes or video measurement systems as part of in-line
production or in final quality inspection.
The following functions are available:
1.1 Overview
Reference mark evaluations for distance-coded and single reference
encoders
Linear, segmented linear and nonlinear error correction
Scaling factor for parts that expand or shrink
Multilingual LCD user interface: language is selected by the user
Soft key functions under LCD change to support different user
activities
Arrow keys for easy navigation of lists and menus
Skew compensation for part alignment prior to measurement,
eliminating the need for time-consuming fixturing
Two datums for absolute and incremental measurements
Axis zero and preset keys for establishing datums
Easy selection of feature measurement type using clearly marked
measure function keys:
Points, lines, circles, distances, angles
Skew for part alignment
Feature measurement can include:
Dimensional measurements of geometric part features
Creation of features by entering dimensional data
Construction of new features from existing features
Applying tolerances
Number keypad with:
Number keys for data entry
Decimal point and +/- keys for data entry
User-defined hot keys that program panel keys to initiate commonly
used functions.
Reports of measurement results sent to a computer over USB-to-
Serial connection
User-defined settings sent to a computer over USB-to-Serial
connection

18 1 Operation
1.2 Basic Functions
Initial power-up
Switch on the power (located on the rear of the
enclosure). After switching the power on, or after a
power failure, the power-up screen will be displayed.
Press the ENTER key to advance from the power-up
screen to the DRO.
Your DRO is now ready for operation and is in the Current Position
operating mode. Encoder position values will be displayed for all axes.
1.2 Basic Functions
Power-up screen
DRO screen
ND 120 QUADRA-CHEK 19
Establishing a repeatable machine zero
If your DRO was configured to establish a machine zero upon powerup, a message will be displayed asking you to cross reference marks
or enter hard-stop axis reference positions. The machine zero is used
by the DRO to apply error correction data as measurements are
performed. To establish a repeatable machine zero you must either:
Move the stage to have encoder reference mark crossings
recognized on each axis or
move the stage to the hard-stop reference position and press ENTER
on each axis when no encoder reference marks are present.
1.2 Basic Functions
Power-off
Notice
If the requirement to cross reference marks is bypassed
by pressing the Cancel soft key, error correction data that
might be stored in your DRO will not be applied.
Switch the power off. The parameter settings and
error compensation tables that have been saved
during operation will be retained in memory.

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
1.3 Preparing to Measure
A repeatable machine zero is required for the DRO to apply the
calibration chart to the machine geometry correctly.
It is not recommended to use the machine without active
calibration. This would lead to unknown position errors.
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.
