Storage and Handling
• This instrument contains precision optics and electronics. You should avoid
knocking or dropping the device as the resulting impact could cause serious
damage.
• In some circumstances the optical components in the instrument could
become misted as a consequence of temperature change. It is
recommended that the instrument is not used until it has stabilised to
ambient temperature.
• Ensure that the instrument is not exposed to moisture, chemicals or to any
corrosive vapours.
• Do not interfere or place any objects inside the measuring aperture as
damage to the measuring system could occur.
• The instrument housing and screen are normally resistant to a variety of
solvents however it is not possible to guarantee resistance to all chemicals,
therefore the surfaces of the instrument should only be cleaned using a soft,
moist cloth.
• Prevent exposure of the instrument to direct sunlight for prolonged periods
and to continuous humidity and condensation.

About the Novo-Shade Duo+
The ovo-Shade Duo+ is a portable 45/0° reflectometer that can be used to assess
either the shade of a surface (a simple indication of colour based on lightness /
darkness) or calculate the opacity of a coating, plastic film or paper sample.
Measuring using 0/45º the ovo-Shade Duo measures the colour of a surface and
not the specular reflectance (gloss). In Shade Mode the ovo-Shade Duo can help
maintain the production quality of the following:
• Shade of paints, inks and coatings
• Fading of textiles and plastics
• Chalking of paint
• Efficiency of detergents and bleaching agents
• Whiteness of recycled paper
• Cleanliness and oxidisation on metal surfaces
In Opacity Mode the ovo-Shade Duo+ can help maintain the production quality of
the following:
• Hiding power of paints, inks and coatings
• Transparency of plastic film
• Opacity of paper
Accessories

the instrument to a PC.
The current batch name is displayed on the home screen in the bottom left corner, the
sample number within that batch is shown in the top right of the screen indicated with
n=(sample number).
A new batch is started using the Start ew Batch option in either the Menu screen or
the Data menu, note that the batch name will increment as will the ‘n’ indicator.
The current batch can be cleared in the either the Menu screen or the Data Menu, the
batch name will remain the same but the ‘n’ indicator will reset to zero.
Auto batch size is user defined using the Auto Batch option in the Data Menu. When the
number of readings in the current batch reach the number set by the user the
instrument will automatically increment the batch name and set the ‘n’ indicator to zero.
Viewing Batch Data
To access the stored batch information connect the instrument to a PC using the USB
data cable supplied.
A new device name “DUO-PLUS” can be viewed and accessed via “MY COMPUTER”,
in this device open the DATA folder. This folder contains subfolders which contain the
data for each individual saved batch. Each reading is saved as an individual comma
separated value (.csv) that contains Measurement Data, Time and Date of Reading,
and Serial umber.
Each reading also contains the statistics for the batch up to and including that reading.
To access the STATISTICS for the whole batch, the last reading in the batch should be
examined.
User Defined Batch Names
Batch names are user definable. With the instrument connected to a PC, open the
folder named “CO FIG”. Within this folder there is a document named “batches”.
This is a .csv file that can be opened in otepad, Excel or Wordpad.
User defined names should be saved in this document each name listed on a separate
line. Ensure that the final line is terminated with a carriage return.
The format of these names should only contain letters, no numbers, spaces or other
characters can be used. Once completed save the file then switch the instrument off
and on again to initialize the new batch names.
