Object Color Measurement - Konica Minolta CHROMA METER Instruction Manual

Object Color Measurement

This implement is capable of simplified object color measurement through the use of the
user calibration function.
○ Ensure that the white calibration plate (optional accessory) and the object to be
measured are set in the same position and angle. If the illumination settings and
measurement conditions are different between the white calibration plate and object to
be measured, the measurement data is affected, resulting in incorrect measurement
data.
○ During the measurement, use a constant-voltage power supply for the illumination light
source to ensure conditions are as stable as possible.
Setup for Object Color Measurement
1.
Prepare one or more illumination
light sources such as tungsten
lamps, and set the white
calibration plate as shown in the
figure on the right.
● Set up the instrument so that it faces the
white calibration plate perpendicularly.
● Set up the illumination light sources at a
45° angle.
