Digital readout for manual 3-D measuring machines


The ND 1400 QUADRA-CHEK digital readout supports four axes: in addition to the linear axes XYZ it features an auxiliary axis Q solely for angular display. The readout is designed specifically for manual coordinate measuring machines, and can capture two- and three-dimensional features with its measuring computer functionality.


The ND 1400 QUADRA-CHEK digital readouts have a large colour touchscreen and are housed in a robust, diecast aluminium enclosure.


Predefined features (point, line, circle, slot, rectangle, plane, cylinder, cone, sphere) 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 all features.

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.

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.

Measuring 3D features


In addition to the flat geometric features, such as points, lines, circles, etc., you can also use the ND 1400 to measure 3-D shapes, e.g. cylinders or cones. The screen displays the feature in three dimensions. Coloured highlighting of each measurement point lets you identify form errors and any filtered measured values at a glance. The ND 1400 also permits 3-D position and form tolerances, such as flatness and parallelism.

Working with the touch probe


The ND 1400 provides support when working with touch probes. You can instantaneously call commercial probing elements (normal stylus, star stylus), as well as rigid and tiltable probing heads, all of which are managed in a library via the touchscreen. During probing the ND automatically takes the direction of probing into account, as well as the length and diameter of the stylus. Even complex parts can be measured rapidly with the five available coordinate systems.
