Digital readout for convenient 2-D measurement


The ND 1300 digital readouts can support up to four axes, and function as measuring computers for 2-D acquisition of measurement points, suiting them for measuring microscopes, measuring projectors and profile projectors, as well as for video measuring machines if the video edge detection option is chosen.


The ND 1300 QUADRA-CHEK digital readouts have a large colour screen and are housed in a robust, diecast aluminium enclosure.


Predefined features (point, line, circle, slot and rectangle) are available for measurement. The “Measure Magic” function makes measurement especially easy. In addition, you can establish relationships (distances, angles) between 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.

Depending on the option installed, the ND 1300 saves measurement points of plane (2-D) contours either automatically or manually via crosshairs, optical edge detection, or a video camera. The integrated image processing function of the video option provides a special benefit: the video image is shown on the screen in real time, and can be saved and output via the data interface. The digital readout even assumes complete control of the illumination and the motor zoom.

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.

Integrated image processing

nd1300 video

The ND 1300 with video option optimally combines in one unit the functions of a position display unit with the capability of displaying the image of the measured object directly on the screen. The separate PC with a frame grabber or monitor with crosshair generator that you would normally need is not necessary. Video cameras with S-Video or composite interfaces can be connected.

Axis positioning

The CNC option lets the ND 1300 work as a full-fledged control, directly controlling the positioning of the X, Y, Z and Q axes. Servo and stepper motors can be connected. The necessary servo amplifiers for two or three axes are available as accessories.
