2.
Press the soft key shown in the fi gure
above and enter the passcode 95148.
Operating Parameters
Important parameters are in bold type.
1.
Encoder Setup
• Encoder Type (linear, rotary).
• Encoder Signal: Automatically
determined.
• Signal Period: Depends on the
encoder.
• Reference Mark: Depends on the
encoder.
• Count Direction: Select the proper
count direction.
• Error Monitor (as required).
2.
Display Confi guration
• Set the display resolution.
3.
Counter Settings
• Lock or release the keypad.
• Second decimal point (after 3 decimal
places).
• Reset all parameters to factory default
settings.
4.
Error Compensation
• Error Compensation: Select OFF ,
Linear or Non-linear, and enter the
data.

Job Setup
Press the SETUP soft key to open the
menu.
1.
Units
Select mm or inches, or degrees/minutes/
seconds (DMS), decimal degrees (DEG)
or rad (display in status bar).
2.
Scale Factor
Deactivate the scale factor, or select the
desired scale factor (display in status bar).
3.
Value for Datum Point
Enter numerical value for datum setting
over switching input or with PRESET
soft key.
4.
Stopwatch
Start the stopwatch (elapsed time is
displayed in status bar).
5.
Console Adjustment
Select the brightness and activate the
display saver.
6.
Language
Select the proper conversational
language.
Before starting a measurement
Ensure that the distance or angle
actually traversed matches the displayed
value and direction. Deviations may be
due to the following causes:
• Signal period
• Counting direction
• Error compensation
• Scale factor
• Distance-to-go display

Functions

REF Reference Mark Evaluation
The ND 280's REF reference mark
evaluation feature automatically
re-establishes the relationship between
axis-slide or measuring-probe positions
and display values that you last defi ned
by setting the datum.
If you do not use the REF feature,
the datums will be lost once the ND is
switched off.
Actual Value/Distance-To-Go
In the Actual Value operating mode, the
ND always displays the current actual
position of the encoder, relative to the
active datum.
In the Distance-To-Go operating mode,
you enter the desired nominal position
and simply traverse to the display value
zero.
The distance-to-go is displayed with
a reversed algebraic sign. For example,
the distance-to-go has a positive sign if
the axis direction from the actual towards
the nominal position is negative.
I: Actual position
S: Nominal position
R: Distance-to-go
