Digital readout for 2-D


The ND 1200 digital readouts can support up to four axes, and function as measuring computers for 2-D geometries. They are mainly suited to optical comparators, measuring microscopes and 2-D measuring machines


The ND 1200 QUADRA-CHEK digital readouts have a monochrome flat-panel screen for displayed values, dialogs and inputs, graphics functions and soft keys. The robust, diecast aluminium enclosure meets the demands of metrology and production control.


Predefined features (point, line, circle) are available for measurement. The “Measure Magic” function makes measurement especially easy: it selects that feature which best matches the shape implied by the points probed. In addition, you can establish relationships (distances, angles) between features.

You can apply tolerance values to features and relationships. Only those tolerances actually possible are offered for the selected feature. You can create or automatically record measuring programs for repeated parts. The digital readout graphically takes you to the next measurement position during program run.

The ND 1200 captures measurement points of plane contours (2-D) either manually via crosshairs or, as an option, automatically via the optical edge detector.

Data Interfaces

You use the data interfaces to output measurement points as well as to load and save settings, compensation values and programs. The RS-232-C/V.24 serial interface enables communication with a PC. You can connect printers or memory media to the USB port.
