Installing The White Calibration Plate - Konica Minolta CM-36dGV Instruction Manual

Installing the White Calibration Plate

The white calibration plate is used to perform white calibration for reflectance measurement, and to perform
transmittance measurement (0% calibration, 100% calibration, measurement).
• Perform this calibration when there is no specimen in the transmittance specimen chamber.
• Install the target mask to use for measurement in advance.
• From the software in advance, set the same measurement area, specular component (SCI/SCE), and UV output
that will be used for measurement.
For fluorescence measurement that does not require strict accuracy (fluorescence calibration is not performed),
perform measurement under UV full light source.
Notes
• When using WAA (Wavelength Analysis & Adjustment), execute it after white calibration. WAA execution
requires approximately 20 seconds.
Procedure
1 Push the sample holder down and hold it so it is opened.
Memo
• Turning the sample holder to the right while it is at its lowest
position will hold it so it remains open.
2 As shown in the figure, fit the sample holder into the
indentation on the reverse side of the white calibration
plate and return the sample holder to its original position.
Precautions for Use of the White Calibration Plate
Memo
• White calibration data is used when performing white calibration using the white calibration plate. White calibration
data is set in the instrument at the time when it is purchased.
• The white calibration plate may become discolored if left exposed to light. Therefore, make sure to close the cap
when the plate is not in use in order to prevent the plate from being exposed to external light.
• Be careful that the white calibration plate does not become scratched and does not contact fingerprints or
other dirt.
• If the white calibration plate becomes dirty, wipe it gently with a soft, clean, and dry cloth.
• If the dirt does not come off easily, wipe it off with a cloth dampened with ethanol, then wipe off the ethanol
with a cloth dampened with water, and allow the white calibration plate to dry before using.
• If the white calibration plate is scratched or the dirt cannot be removed, replace it. After the white calibration
plate was replaced, set the white calibration data to the data for the new white calibration plate.
