MANUAL CALIBRATION PROCEDURE
The manual calibration procedure is used to correlate the low densities of the
instrument to another densitometer. Doing this allows the instrument to
measure approximately the same as another densitometer that has Status A
reflection response, and has been calibrated to ANSI Standards.
1. Using the instrument's own reference, calibrate the densitometer that you
want this instrument to correlate with.
2. Using the same densitometer, measure the white area below the first
black bar on the X-Rite Auto-Cal strip and record the Red, Green, and
Blue values.
