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:
 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
