Transmittance Measurement 100% Calibration Procedure
Transmittance measurement 100% calibration is performed with
nothing set in the transmittance specimen chamber.
• 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.
For fluorescence measurement that does not require strict accuracy
(fluorescence calibration is not performed), perform measurement
under UV full light source.
When the below setup is completed, execute 100% calibration
from the software.
Procedure
1 Open the transmittance specimen chamber cover.
2 Empty the space between the illumination window
and receptor window. (Perform without a sample,
transmittance zero calibration plate, or other item
installed.)
Memo
• There will be no effect on the measurement results if the optional
transmittance specimen holder CM-A96 is installed. However in
this case, it is necessary to perform measurement with the zero
calibration transmittance sample holder installed.
3 Close the transmittance specimen chamber cover.
