Indexing Mode

  • Accuracy: 0.5 sec + 0.2% of displayed reading
  • Index step size (resolution): 1º
  • Range: Multiple rotations or partial arcs

Laser Measurement Mode

  • Accuracy: 0.2% of displayed reading (Accuracy can be improved by calibrating laser optics with the indexing table)
  • Range: ±10º

Setup Requirements

  • Travel (using +2 mm, -1 mm machine axis or manual from zero reference)

Indexing Mode (Interferometer in fixture)

  • Maximum lift: 15 mm (2 mm required for fixture)

The Keysight 55290A Angular Position Measurement Kit automatically calibrates rotational axes in turning and machining centers. It can perform calibrations on full, partial or multiple rotations, improves angular positioning accuracy, and allows the documentation of machine tool capability. 

  • Keeps the laser beam on indexing tables that require a great deal of lift - up to 15 mm
  • Performs partial arcs for tools that cannot rotate 360° as well as multiple rotations
  • Calibrates C-axis on turning centers
