Controls and Displays
1Status bar
Current operating mode: Actual Value, Distance-To-Go.
Current display mode for input X1, X2 or coupled axes X1:X2.
SCL shown in black: Scaling factor is active.
COMP shown in black: Error compensation or axis-error compensation is active for the currently displayed axis
or coupled axes.
Elapsed time of running stopwatch: If the stopwatch is stopped, the box appears dimmed.
mm, inch, DEG, DMS or rad: Currently active unit of measure
Currently active datum: The ND 287 allows you to work with two different datums.
Indicates the soft-key page (soft-key row) you are currently on.
2Position display: Current position value (length or angle), or other measured value
3Message line for displaying information, errors or warnings.
4Status display:
<• / = / >: The first three symbols become effective when tolerance checking and sorting mode is activated.
MIN, ACTL or MAX and DIFF: Minimum, current or maximum measured value of a series of measurements,
or difference between minimum and maximum measured value.
SET: If you enter a new value during datum setting, the SET symbol will start flashing.
REF: The REF symbol is flashing until the reference mark evaluation for the displayed axis has been
completed (if an incremental encoder is connected).
5 and 6 Soft keys and soft-key buttons for executing functions.
1,2,3,4... Numeric input keys.
ENTER Use the ENTER key to confirm your entry or to return to the previous screen.
C Use the C key to clear an entry, acknowledge an error message or return to the previous screen.
The NAVIGATION key moves through the soft-key pages (soft-key rows).
7Use the UP or DOWN arrow key to move between fields within a form or menu items (parameters) within a
menu.

Introduction
Introduction
Software version
The software version is shown on the power-up screen of the ND 287.
Symbols within notes
Every note is marked with a symbol on the left indicating to the
operator the type and/or potential severity of the note.
Fonts
The chart below shows how the different variables (soft keys, hard
keys, forms and form fields) are represented within the text of this
manual:
Soft keys – SETUP soft key
Hard keys – ENTER hard key
Menus and forms – UNITS OF MEASURE form
Parameters and input fields – ANGULAR field
Data in fields - ON, OFF
This manual describes the functions that are available in
the ND 287 and the installation of the units.
General information
e. g. on the behavior of the ND 287.
Refer to accompanying documents
e.g. when a special tool is required for a function.
Danger to the operator, workpiece or internal
components
e.g. danger of collision
Electrical hazard
e. g. danger of electrical shock when opening a housing.
The ND 287 must be prepared by a qualified and
authorized technician to perform this function.
