Calibrating DMIx SamplR

Calibration is a critical step in ensuring the accuracy and consistency of your DMIx SamplR scans. The calibration process adjusts the scanner and iPhone to match the environmental and device-specific conditions, enabling precise color and texture reproduction. It is mandatory before the first use and re-calibration is recommended on a regular basis.

When to Calibrate

• Initial Setup: Calibration is required when the SamplR is used for the first time.
• After Moving: If the scanner is relocated to a new environment.
• Device Changes: After replacing the iPhone or the phone adapter.
• Periodic Use: Recalibrate after approximately every 3 months or when scans show inconsistencies.

Required Tools

Black & White Level Calibration Targets:

• Provided with the scanner. You will find them in the box containing the accessories. Please note that both calibration targets are protected by an additional piece of cardboard. Please remove this first to access both targets.

  

Replace the calibration paper if it becomes bent, dirty, or damaged.

Calibration Paper needs to be stored in a dark environment at any time.
