UltraScan VIS
UltraScan VIS Standardization
The UltraScan VIS must be standardized on a regular basis to keep it operating properly.
General
Standardization sets the top and bottom of the scale for the photometric scale. During standardization
the bottom of the scale is set first. For this, you simulate the case where all the light is absorbed by the
sample. For UltraScan VIS, the bottom of the scale is set with the light trap for reflectance modes. The
black card device is used to set the bottom of the scale for transmittance measurements.
The top of the scale is then set by scaling the light which is reflected or transmitted to a calibrated
standard. This is done using a calibrated white tile for reflectance measurements and air or a solvent-
filled cell for transmittance measurements. On-screen messages prompt you through the standardization
procedure.
Standardizing on the black
card device for TTRAN
mode. (The transmission
compartment door may be
closed down to the device
handle.)
Standardizing on the black
card device for RTRAN
mode.
