Storag 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.
Acc ssori s
• Certified calibration tile with certificate
• Instruction manual
• Tile cleaning kit
• 4 x AA batteries

M asuring Gloss
Ch ck th 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 measured value with the
assigned value 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 th Novo-Gloss 20/60/75°
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.
Tak a singl r ading
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 th mov and r ad f atur
The Novo-Gloss 20/60/75° has a unique feature to quickly assess large
surfaces for gloss variation.

Novo-Gloss 20/60/75º Manual
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 20/60/75° 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 insp ction and til car
It is necessary to inspect the condition of the calibration tile and instrument
optics before each calibration.
Insp cting and cl aning th instrum nt 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.
Insp cting and cl aning th calibration til
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.
Scratch d or damag d til s
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.
Calibration
Z ro Gloss Calibration
For improved stability and accuracy the Novo-Gloss 20/60/75° 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
Calibrat a singl angl
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 > 75.
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.
6
Inspect the tile and
instrument optics before
calibration.

Novo-Gloss 20/60/75º Manual
Calibrat all angl s
To simultaneously calibrate all three angles, use the “C” key to cycle through
the read modes until the three angle 20 60 75 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 ch ck
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.
Analysing Statistics
To examine the statistics for the stored values, whilst in Read mode – press the
up arrow.
D finitions of t rms us d in statistical mod
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
which the 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.

Place the instrument on
the tile.
Press and OLD the ‘C’ key
to start calibration.

Pr f r nc s
Changing th calibration valu
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
Calibrat at low, m dium or high gloss valu
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 20/60/75° 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.
Chang calibration valu s in th s t up m nu
In read mode, press the C key to cycle through 20/60 or 75º 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.
• Press the READ KEY when the value is correct, if required repeat the
process for the remaining angles.
