Calibration Information
Standards
The instrument comes with 2 calibration standards.
The black trap is used to perform the zero
reflectance calibration (black calibration). Always
store the black trap with the protection cover in
place when not in use.
The white standard is fixed in a case that has a
hinged cover. It is used to perform the 100%
reflectance calibration and to calibrate the camera.
Additionally two checking standards are supplied to
audit instrument performance:
A cyan standard for color and an effect standard for
sparkle and graininess (only with BYK-mac i).
When calibration is required, the device will display
a message.
The cyan check must be accomplished every 30
days. Black and white calibration must be
accomplished every 3 months.
It is recommended to perform the effect check also
once per month.
