Installing the Transmittance Zero Calibration Plate
²
(Option)
The transmittance zero calibration plate is used when performing 0% calibration for transmittance measurement.
• When using the optional SpectraMagic NX, set the measurement method to transmittance in advance.
• Install the target mask for LAV measurement and the white calibration plate onto the instrument.
Procedure
1 Open the transmittance specimen chamber cover.
2 Install the transmittance zero calibration plate in a
position so that it completely covers the illumination
window.
Memo
• When using the optional transmittance specimen holder, install
the transmittance zero calibration plate into the transmittance
sample holder. For information about installing the transmittance
specimen holder, refer to the instruction manual that was
provided with the transmittance specimen holder.
3 Close the transmittance specimen chamber cover.
Precautions for Use of the Transmittance Zero Calibration Plate
• Be careful that the transmittance zero calibration plate does not become scratched and does not contact
fingerprints or other dirt.
• If the transmittance zero calibration plate becomes dirty, wipe it gently with a soft, clean, and dry cloth.
• If the dirt does not come off easily, wipe using a soft cloth dampened with ethanol.
• If the transmittance zero calibration plate is scratched or the dirt cannot be removed, replace it.
