Readout System For Video Based Metrology Applications

Metronics Inc. ( has introduced the Quadra-Chek 300 (QC300), an advanced digital readout system that combines multiple video measuring functions in a single, compact display unit. Metronics proprietary technology combines video display, cross line generator and automated edge detection, providing improved accuracy, increased measuring speed and reliability.

The QC300 features a large, highresolution LCD monitor for vivid, full color display of parts, 2-D measurements and controls, plus integrated direct camera input that provides "live feed" video display. Parts and video measuring routines are displayed in one line of sight, on one screen. Automated video edge detection is also offered. The QC300 is ergonomically designed with intuitive, touch screen functions and graphical icons.

The QC300 has enhanced programming features such as alpha-numeric program naming, user messages, and "arrow to target" stage directions to operator. The automatic point entry, based on stage movement to the correct position, provides faster measuring throughput and with the auto edge detection option, operator subjectivity is also removed, reducing errors.

Four video tools are offered with the integrated video edge detection option:

  • Straight Crossline—which allows operator to select edge position.
  • Offset Crossline—for locating difficult edges.
  • Single Edge—automatically finds a point along an edge within a circular target.
  • Multi-Edge—arrow targets direct stage positioning for multiple points along an edge.

Multiple feature types are also provided with the QC300, such as Measuring Magic and constructions. Tolerance displays translate data-intensive reports into at-a-glance visual displays that are easy to read. The QC300 will also record measuring routines and store them as a program.

QC300 interfaces to USB ports for computers and printers, RS-232 for serial communication, and an I/O port for interface to lights sources. BNC and S-Video connections are also provided with the video edge detection option.
