How do I know my instrument is reading and performing correctly?

Follow

The Hunter OQ Operational Qualification for your instrument are the two (or three for sphere instruments) built-in diagnostic tests in EasyMatch QC (or stand alone in MiniScan EZ and ColorFlex EZ). In EZMQC go to Sensor/Diagnostics for the following diagnostic tests or the Diagnostics menu from your instruments main menu.

  • Short Term Repeatability on White Tile to verify the electronics are in good health.
  • Long Term Repeatability on the Green Tile to verify the photometric and wavelength performance of the entire optical path is the same as when last at factory.
  • Wavelength check on sphere instruments with the Didymium filter to ensure instrument alignment.

A PASS on all applicable diagnostic tests affirms the instrument is operationally qualified as being in good working order. This is the basis for all HunterLab instrument performance verification.
