Continuous reading mode
Using the move and read feature
The Novo-Shade Duo™ has a unique feature to quickly assess large
surfaces for shade variations.
To use this feature press and hold the READ/SELECT key.
The unit will now start to take a reading and a line of arrows will move
across the screen whilst the instrument takes the measurement.
A value will be shown in the display – this is the reflectance value for the
part of the sample currently covered by the measurement aperture.
To assess the rest of the sample continue to hold the READ/SELECT key
and carefully slide the instrument to the next area to be inspected.
The value in the display will update in real time to reflect the shade value
of the surface under the aperture at that time.
As soon as the READ/SELECT button is released the last value
measured will be displayed. This is also the value stored in the memory.
Taking subsequent readings
Repeat the above procedure to take further readings. Each time a
reading is taken the number of samples stored increases by one. If an
erroneous measurement is taken it can be deleted (see pages 20-21).
