6.2.3 Cleaning the Calibration Reference
The calibration reference consists of a ceramic disk for white
calibration measurements and a trap opening for black
calibration measurements.
The white ceramic disk can be cleaned periodically using a
mild soap and warm water solution, thoroughly rinsed with
warm water and wiped dry with a lint-free cloth. Do not use
solvents or cleaners of any kind.
The black trap portion of the reference should be cleaned with
clean, dry air from time to time to remove any dust or
contamination. The reference can be taken apart for easy
cleaning of the black trap by compressing the two locking tabs
on both sides of the case with your fingers, and separating the
two sections.
NOTE: When reassembling the black trap, make sure the trap opening is
positioned over the cone in the bottom portion of the trap. The tabs will
not lock correctly if assembled in the opposite direction.
Make sure to store the calibration reference in a dry, dust free
area, away from direct exposure to light.
