Multifunction Digital Readout – QualiDigi™ Readout 400

Video Measuring Projector inspections get faster when measurement, math, and reporting happen in one place. QualiDigi™ Readout 400 is a multifunction digital readout designed to process X/Y/Z (or X/Y/Q) signals from linear scales, display results in mm or inch, and support common geometry measurements on-screen.

A 5.6-inch color display and sealed silicone keypad help keep operation straightforward in daily QC work.

Multifunction Digital Readout – QualiDigi™ Readout 400 Applications

  • Dimension checks and routine QC
    • Use DP400 to calculate distances, angles, and feature locations while running a Video Measuring Projector inspection. Built-in functions reduce manual calculations and help standardize operator workflow.
  • Geometry measurement for profiles and features
    • Supports measurement of points, lines, circles, angles, rectangles, ellipses, slots, rounding, and constructed elements. This is useful for profile verification on machined parts, stamped components, and small hardware.
  • Multi-axis compensation and repeatable setups
    • Section and linear compensation are available for three axes to help maintain consistent readings after setup or service. Password permissions also help protect settings from accidental changes.
  • Peripheral integration for smoother inspection
    • Connect accessories such as a foot switch, printer, and optical edge finder to streamline measurement capture and documentation. RS232 output supports basic data export to external systems when needed.

Standards

  • ISO 14253-1: Decision rules for verifying conformity/nonconformity considering measurement uncertainty.
  • ISO 14978: General concepts and requirements for GPS measuring equipment (useful framework for equipment characteristics and calibration concepts).
  • ISO 10360-7: Acceptance/reverification concepts for imaging probing systems (often referenced for imaging-based measurement performance discussions).
  • ASME B89.4.1: Methods for specifying and testing CMM performance (commonly referenced in US metrology programs).

Multifunction Digital Readout – QualiDigi™ Readout 400 Key Features

  • Rigid granite structure
    • Granite base and column improve stability for consistent measurement results.
  • Low return error stage movement
    • A toothless polished rod with a fast-lock mechanism keeps table return error within 2 µm.
  • Accurate scale and precision stage
    • A high-precision optical scale and precision worktable support E1 accuracy up to ≤ 3 + L/200 µm.
  • Clear, distortion-controlled imaging
    • The zoom lens and high-resolution color camera provide sharp images for reliable edge finding.
  • Dual illumination for projector-style measurement
    • LED cold surface lighting and bottom LED parallel lighting support reflected and transmitted viewing.
  • Crosshair visibility tuning for faster targeting
    • Adjustable cross-line color helps operators align measured points more easily on-screen.
  • Digital readout for measurement processing
    • A multifunction color-screen digital readout processes measurement data and supports inspection workflows.
