Measuring Gloss
Check the Calibration
If the instrument has not been used for some time it is
advisable to check the calibration.
Place the instrument on the high gloss calibration tile. Take
a reading by pressing the READ/SELECT key. Compare the
measuredvalue with the assignedvalue for the tile.
If it matches the value on the tile holder, the instrument is
within calibration and ready for use.
If the measured value does not match the assigned value,
follow the calibration procedure (see page 6).
Positioning the Novo-Gloss Trio
When the instrument is placed on a sample the aperture is
hidden, the centre of the measurement area can be
pinpointed by the intersection of the arrows marked on the
front of the instrument case with those on the side.
The “UP/DOWN” key
The “C” key
Place the instrument in the
calibration holder.
The measurement position is
indicated by the arrows.

Take a single reading
Press and release the READ/SELECT key in measurement
mode to take a single reading.
The value shown in the display is the gloss value for the section
of the sample covered by the aperture. This value has been
stored in the memory and the number of stored readings
increased by one.
Using the move and read feature
The Novo-Gloss TrioTM has a unique feature to quickly assess
large surfaces for gloss variation.
To use this feature PRESS and HOLD the READ/SELECT key
whilst in read mode. The unit will take a reading.
A value will be shown in the display; this is the gloss 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 Novo-Gloss Trio to
the area to be inspected.
The value in the display will update IN REAL TIME to reflect the
gloss 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.
Calibration inspection and tile care
It is necessary to inspect the condition of the calibration tile and
instrument optics before each calibration.
Inspecting and cleaning the instrument optics
Any dust or debris on the optic should be blown from the lenses
using dry clean air- the optics must not be touched without
wearing suitable cotton gloves.
If there are any permanent marks or scratches on the lenses,
the instrument is no longer suitable for measuring gloss and
should be returned to an authorised Rhopoint service center.
Inspecting and cleaning the calibration tile
The calibration tile must be perfectly clean from smears and
scratches before attempting calibration. Fingerprints and dust
can be removed with the supplied optic cleaning cloth.
Scratched or damaged tiles
Scratched or damaged tiles are not suitable for gloss
calibration. The instrument and tile must be returned to an
approved Rhopoint service center for tile replacement and re-
calibration.
Press the “READ” key to
take a gloss measurement.
Press and HOLD the “READ”
key to take a continuous
gloss measurement.
Inspect the tile and
instrument optics before
calibration.

Calibration
Zero Gloss Calibration
For improved stability and accuracy the Novo-Gloss Trio is supplied
with the Zero calibration feature switched on. During calibration the
instrument will prompt “Sample Zero Ref”, at this point the
instrument should be placed on the enclosed zero reference foam
and the “Read” key pressed to take a reading.
See page 8 for instructions how to switch on/off the Zero calibration
feature
Calibrate a single angle
Place the instrument in the calibration holder. In measurement
mode, select the required angle, pressing the “C” button to cycles
through the angles 20 > 60 > 85.
Once the required angle is displayed, press and hold the “C” key to
begin the calibration procedure. Follow the on screen instructions to
complete this process.
Calibrate all angles
To simultaneously calibrate all three angles, use the “C” key to
cycle through the read modes until the three angle 20 60 85 degree
read mode is displayed.
The “C” key should then be pressed and held until the calibration
procedure starts. The on-screen instructions should be followed to
complete the calibration process
Automatic calibration check
During calibration the instrument automatically checks for changes
in the condition of the calibration tile.
If changes to the expected value are detected the instrument will
prompt
“Possible Calibration Error- Check Calibration Tile”
The calibration tile and instrument optics should then be carefully
checked for marks or scratches.
If there are smears mark or dust on the optics, press the “C” key to
abort the calibration, and clean tiles and optics using the above
procedure and repeat the calibration process
If the calibration tile is seen to be completely clean, press the read
key to store the calibration data.
The “C” key can be pressed at any time to abort the calibration
process.
Place the instrument in the
calibration holder.
Press and HOLD the “C”
key to start calibration.

Analysing Statistics
To examine the statistics for the stored values, whilst in
Read mode -press the up arrow.
Definitions of terms used in statistical mode
For this purpose the individual readings are defined as
values x1, x2, xn, and xi is any data point:
-Statistical sample population, n- the current number of
stored readings on whichthe statistical analysis is based.
-Maximum (MAX) - the highest reading.
-Minimum (MIN) - the lowest reading.
-Mean (MEAN), - The sum of all readings divided by the
total number.
-Standard deviation (SD), s- Square root of the sum of
squared --deviations from the mean.
-Coefficient of variation (CV), c- Standard deviation
divided by the mean, a measure of data scatter.
Preferences
Changing the calibration value
The instrument is supplied with the assigned values of the
standard tile stored in the instrument memory.
These values are updated when the instrument is
recalibrated by an authorised service center.
The stored values can also be changed by the end user if an
alternative tile is to be used for calibration
Calibrate at low, medium or high gloss value
It is often desirable to calibrate using a standard that closely
matches the gloss of the samples to be tested.
Rhopoint supply a range of gloss, semi-gloss and matt tiles
to suit all applications. To calibrate the Novo-Gloss Trio using
a purchased tile, the calibration value in the instrument
memory must be adjusted to match the assigned value of the
new tile.
Rhopoint also supply mirror tiles for verification of measured
values at very high gloss levels. The instrument should not
be calibrated on a mirror tile.
Change calibration values in the set up menu
In read mode, press the C key to cycle through 20/60 or 85º
angles until the required angle is displayed.
Access the hidden set up menu using the following key press
combination;
-First press and hold the DOWN button.
-Press and hold the C button whilst continuing to press the
DOWN button.
-Wait until “SYSTEM SET UP” appears in the display.
-Scroll up/down until “SET STD CAL VAL.” is shown on the
display.
-Press the read key to change this value.
-Use the UP/DOWN arrow to adjust to the assigned value of
the calibration tile.
To access hidden menu-
Press and HOLD the “C”
and “DOWN” keys.
