Functions  Multilingual user guidance
 REF reference-mark evaluation for distance-coded or single reference marks
 Display for lengths, angles, or optionally for other measured values from analog
sensors
 Distance-To-Go or Actual Value operating mode
 Two datums
 Scaling factor
 Stopwatch
 Reset or Preset function, also through external signal
 Linear or non-linear error compensation for axis-error compensation
 Trigger signals
 Sorting and tolerance checking function with capacity for saving the
tolerances of 10 parts
 Series of measurements:
 Sorting measured values and finding the Minimum, Maximum, Sum,
Difference, the traversing speed or a definable coupled position value.
Displaying the sorting results in order to intervene, if necessary.
 Memory capacity for series of measurements: Up to 10 000 measured
values per axis.
 Analysis of series of measurements: Arithmetical mean value, standard
deviation
, graphical representation of all measured values with minimum,
maximum and mean value of the series of measurements.
 Measured-value acquisition by external signal or selectable sampling
interval
, or by pressing the ENTER key.
 Statistical Process Control (SPC) :
 Calculation of arithmetical mean value, standard deviation and range.
Displaying graphs or histograms with symmetrical or asymmetrical
density function
.
 Process capability indices c
p
and c
pk
, quality control charts for mean
value, standard deviation and range.
 Measured-value acquisition by external signal or by pressing the ENTER
key.
 FIFO memory capacity: Up to 1000 measured values
 Diagnostics function
for testing the encoder, the keyboard, the screen, the
supply voltage and the switching inputs/outputs
 Data transfer of measured values and compensation values, configuration
parameters or software downloads via a serial interface
 Integrated help system
Error compensation  Linear axes: Linear and non-linear (up to 200 compensation points)
 Rotary axes: Non-linear (180 fixed compensation points spaced at 2°)
 Axis-error compensation with temperature sensor
 Temperature compensation using a reference part
