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 due to 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.

Power
The Novo-Gloss is powered by an integrated high capacity lithium ion cell.
Fully charged the instrument will operate continuously for >17 Hours or >20,000 readings.
A mains powered USB charger is provided with the unit, this will fully charge the unit when
connected to the units USB input (6) using the USB cable provided in under 3 hours.
Alternatively, the Novo-Gloss can be powered and charged using the USB cable attached
to any compatible USB host (e.g. laptop etc.), however due to the lower current available
from these devices, the charge time will be a minimum of 6 – 8 hours.
Do not operate the instrument whilst it is charging.
USB Connectivity
Three functions are available when the Novo-Gloss is connected to a computer using the
USB cable supplied –
Access Files – Allows access to measurement and configuration files on the instrument. The
instrument appears as a USB drive named NG-METER. When selected the display on the
instrument shows a USB memory key as shown below –

7
USB Remote Control - Allows control of the Novo-Gloss remotely by sending ASCII
commands from a computer or PLC. In this mode the instrument displays “REMOTE
CONTROL ACTIVE” on the main measurement screen.

Operation
With the unit switched on and initialised the instrument will display the Home screen
as shown below.
In this mode, measurements can be made by simply pressing the operate button (4)
on the instrument’s keypad. If the Auto Calibration option is set to ON in the settings
menu (detailed later in the Instrument Settings section of this manual) a dialogue box
will appear when the operate button is pressed as shown below
Two options are available: either to “Calibrate” the instrument on the calibration tile
before making the measurement or to “Measure” without performing a calibration.
Using the Left / Right (3) and Enter (4) buttons on the keypad the required option can
be selected.
Selecting “Calibrate” the instrument will perform a calibration and display a
confirmation dialogue box when completed. Selecting the “Confirm” option will save
the calibration information to the instrument’s memory, which will also be confirmed by
the calibration tile Gloss and IQ* readings appearing on the instruments display.
Alternatively, if “Cancel” is selected the display will return to the Home screen.
Selecting “Measure” the instrument will perform a measurement and after 3 -4
seconds display the results.
*The IQ screen is only available on the Novo-Gloss 20/60/85 with Haze.

With the pass / fail feature enabled, the Novo-Gloss will compare each measurement
angle to user defined tolerances. If the gloss reading is within specification, the angle
header will be displayed in Green. If the reading falls outside the tolerances the
header is marked in Red.
Press the Right button in the Home screen to access the gloss statistics screen for the
current batch for all three angles. Measurements can be taken whilst in this screen
and the statistics will be updated.

10
If the Pass / Fail feature is enabled, the colour of the angle header indicates if the last
reading is within the user defined tolerances.
Press the Right button in the gloss statistics screen to access the gloss graph screen,
which gives a graphical representation of the statistics data.
Measurements can be taken whilst in this screen and the graph will be updated after
each reading.
Press the Left button to return to the statistics screen.

Batching Options
The batching feature allows the user to group measurements together in batches. Each
batch has associated statistics; the data for each batch can be accessed by connecting
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 New 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 “IQ-METER” 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 Gloss, Haze, DOI/RIQ, RSpec, Time and Date of Reading, Serial
Number and Full Goniophotometric data for all 512 diode elements.
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 “CONFIG”. Within this folder there is a document named “batches”. This is a
.csv file that can be opened in Notepad, 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 and then switch the instrument off and on again to initialize
the new batch names.

Red. Saved data and data transmitted by Bluetooth will also contain a pass/fail field.
Selecting the Done option will complete this process.
