Choosing between Shade and Opacity modes
Measuring using 45/0˚ geometry, the Novo-Shade Duo™ excludes the
surface specular reflectance (gloss) component and looks only at the
colour or shade.
Shade mode
– the measured value can be used to grade surfaces from
black (0% reflectance) to brilliant white (100% reflectance). Coloured
surfaces can also be measured; the value will indicate the luminous
intensity of the colour (lightness/darkness).
Opacity mode
– the sample must be drawn down on or measured over
a substrate with black and white portions. The instrument uses these
measurements to automatically calculate the hiding power or opacity of
the sample.
Switching between Shade and Opacity modes
To turn the instrument on press the POWER key. For two seconds
the display will show the following message:
The display will then indicate the current measurement mode of the
instrument.
After two seconds it then will revert to measurement mode.
