PREVENTIVE MAINTENANCE

Maintenance checklist

Each session

  • Clean the measuring port

Monthly

  • Inspect tiles for scratches, chips or soiling
  • Chart check-tile ΔE* to spot drift

Annual

  • Service and recalibration by the maker or an accredited lab, including wavelength and photometric checks
  • Recertify the white tile and check tiles (for example a BCRA-type tile set)
