System description

4. System description

Measurement units of the portable glossmeter
family can be used to determine the gloss level of
paint coatings, plastics, ceramics and metal
surfaces.

Light is directed at the surface of the sample at a
defined angle and the reflected light is measured
photoelectrically (reflectometer).

Depending on the typical gloss level of the test
object, reflectometers that direct light onto the
surface at different angles (geometry) can be used.

Measurement units are equipped with standard
geometries of 20°, 60° or 85°. All three of these
geometries are integrated into the three angle units.
Functions described in this manual in terms of
geometry selection are only available with the three
angle device.

In addition to measuring individual gloss values, it is
also possible to record, save and statistically
evaluate series of measurements consisting of up to
999 values.

The operate button and scroll wheel are used to
control the system. System operation is supported
by display messages (autodiagnosis and error
messages).

The measurement unit conforms to the standards
ISO 2813, ASTM D 523, ASTM D 2457, DIN 67530
and ISO 7668, JIS Z 8741 (excluding 60°S)

Controls

The basic system consists of the measuring device
and the protective holder.

The protective holder is used for calibration and to
store the measurement unit. Calibration is
performed inside the holder automatically at the
touch of a button. The gloss standard required for
this purpose is kept in the holder and is positioned
in such a manner that calibration is always
performed at the same point.

When the device is turned on inside the holder, it
performs a self-test (autodiagnosis).

If you will not be using the measuring unit, please
store it in the protective holder. In this way the
measurement optics are protected from dirt and
dust and the calibration standard is always readily
available.

The operate button and scroll wheel are used to
control the system. Pressing the wheel turns the
unit on and causes a menu to be displayed. All
settings within the menus are made by turning and
pressing the wheel.

Pressing the operate button starts measurements or
performs functions that are displayed. In addition,
you can return from the various menus to mode with
the operate button. System operation is supported
by an autodiagnosis test, comments and error
messages. Measurement values and comments
appear in the display.

7.1 Turning on the unit and measuring

To turn on the unit, press the mode scroll wheel.

Information on the date and last certification appears
in the display. If the device was turned on in its
holder, the autodiagnosis test is performed (see the
section on Calibration).

Then the unit switches into the last measurement
mode to be selected.

Pressing operate initiates measurements.

The display of measurement results on the screen
may be broken down into the following elements:

A: When Difference measurement is turned on,
the name of the standard that is selected is
displayed here.

B: If Memory is selected, the memory area that
is selected appears at the top left and for

C: the sample name (block name).
D: If Statistics or Continuous is turned on, the

number of measurements performed or selected is
displayed here.
The measurement values appear in the lower part of
the display area. The size of the numbers depends
on whether Statistics or Difference measurement
has been activated and on the number of geometries
displayed. Depending on the measurement mode, a
header line also appears for the measurement
values.

19

Getting started

7.2 Navigation

All control functions are controlled by the mode
scroll wheel. Pressing the wheel causes a menu to
appear in the display. Turning the wheel allows you
to move the black mark to the desired function and
to select or activate it by pressing the wheel.

What functions are displayed in the menu depends
on the settings in the main menu. The main menu is
the “central” level and can always be reached
quickly.

Certain rules apply within the menus to make it
easier to navigate:

A black triangle to the right of a function indicates
that selecting this function will take you to a sub­menu.

A check mark on the right indicates that the function
in question has been activated.

You can use the arrow at the top right to switch the
display back by one level.

Arrows pointing up or down indicate that there are
other menu options above or below the part of the
menu that is visible. To reach these menu options,
simply turn the scroll wheel in the direction in which
the arrow is pointing.

You can quickly switch back from the menus to the
measurement display by using the operate button.
In some cases this button also has another
function, but that will be indicated in the display (for
example Confirm -> operate).

Calibrate

8. Calibrate

The holder with the integrated glass standard is
used for calibration. Always keep the measurement
unit in the holder. This protects the measurement
optics and ensures that the standard is always at
hand.

If you have several devices of this type, you must
put the unit in the holder which belongs to the unit
(see the serial number).

Make certain that the standard is clean and
there are no cracks on it.

When you place the device in the holder, make
certain that it ships firmly into place.

8.1 Autodiagnosis

Whenever you turn on the device in the holder, it first
performs a self-test. During this test, any changes in
the measurement signal are tested against saved
calibration data. This allows for a long-term calibration
so that a new calibration is required only about once a
week. Beyond that, calibration is only necessary if
there are significant weather changes (see under 8.2).
It is recommended that you perform the self-test in the
holder regularly (every day).

The autodiagnosis generally takes about 2 seconds.
“Please clean standard” or “Please test standard”
may be displayed. For more information on
cleaning, see Chapter 20.

A message will appear in the display informing you
that the autodiagnosis has been completed
successfully.

In some cases, the system may suggest that you
repeat the calibration. The reason for this may be
changed ambient conditions. It is also possible,
however, that the standard still has small amounts
of residue left over from cleaning. This problem can
generally be alleviated by cleaning with a dry optical
cleaning cloth.

23

Calibrate

8.2 Calibrate

You should recalibrate the device if ambient
conditions have changed. This applies especially
when changing location if major changes in
temperature and relative humidity may be expected
as a result (for example inside/outside).

When moving from cold areas to warm areas, there
is a danger of condensation. For this reason, after
there has been a change in ambient conditions, you
should wait for an appropriate amount of time to
allow the optical components to adjust before
calibrating and using the unit.

Use the path shown on the left side to reach the
Calibrate menu option.

8.2.1 Gloss

To begin calibration, press the scroll wheel.
The calibration process is performed automatically

for all three geometries. The saved calibration values
of the standard appear in the display.

The unit then returns to the selection menu
Calibration.

24

8.2.2 Change cal.values

The gloss values of the calibration standard in the
holder included with delivery are saved in the
measuring device. During automatic calibration, this
data is assigned to the standard in the holder.

In some cases it will be necessary to enter data for
a new calibration standard, for example if the
previous standard has been damaged or scratched.

To ensure exact calibration, only original
standards from the manufacturer should be
used.

You can use the path shown on the right side to
reach the Change cal.values menu option.

At three angle units, a selection menu will appear
for geometries. Select the desired geometry and
press the scroll wheel.

A warning message appears. You can cancel this
process by pressing the operate button.

If you press the scroll wheel, you will continue with
the process of changing calibration values.

In the next display you can enter new calibration
values.

Calibrate

25

8.2.4 Scale Gloss

You can use the Scale menu option to switch back
and forth between Gloss Units and Reflectance (see
the Section on Practical measuring suggestions).
Move the mark to the desired entry and press mode.
A check mark identifies the Scale that is selected.
After you switch the Scale, the unit must not be
recalibrated.

Calibrate

After you have entered the new value, a warning
message appears again in the display. You can
again abort the process with operate.

If you confirm the new value by pressing the scroll
wheel, the value will be accepted.

After you have changed all necessary values, you
should recalibrate the measurement device as
usual.

8.2.3 Status

This menu item provides you with information on the
calibration status of the unit.

In particular, you can check here whether the saved
calibration values match those of the holder. The
display also indicates if an error message was
generated as a result of the last autodiagnosis or
calibration. If this has happened, further information
is available under Section Errors and warning
messages.

26

Calibrate

8.3 Calibrating standards

To ensure exact calibration, only original standards
from the manufacturer should be used.
These are calibrated against tested primary
standards. Their surface must not be touched and
must be protected against scratches. Due to
environmental influences, however, the values of
standards can change over the course of time even
if they are handled gently. For this reason, you
should have the calibration standards tested by the
manufacturer at regular intervals (we recommend
annually).

8.4 Checking standard

We recommend the regular use of a separate test
standard for control of test equipment. The
frequency of this verification depends on the
conditions of usage (for example monthly). The
gloss standards are integrated into an aluminum
guide in which the measurement device is
positioned exactly. Perform the measurement as
you would normally, for example in Basic mode. The
displayed measurement value must not deviate from
the value printed on the standard by more than one
unit. Otherwise you should check whether there is
dirt and dust on the high gloss standard in the
holder or test standard. If cleaning and recalibration
do not offer any improvement, please get in touch
with our Customer Service.

27

Measurement techniques

9. Measurement techniques

In accordance with the standard, the reflectometer
value is related to a black glass standard at a
defined index of refraction (generally 1.567) which is
thus equal to 100 units.

Reflectometers are differentiated by the angle of
incidence of the illuminating mechanism.
Geometries are set in the standards at 20°, 60° and
85°.

9.1 Paints and varnishes, plastics and similar materials

The various geometries are distinguished according
to their fields of application as follows:

Semi-gloss surfaces are measured at an angle of
incidence of 60° and should fall within a range from
10 to 70 gloss units.

Highly reflective surfaces with measurement values
exceeding 70 units in the 60° geometry should be
measured at 20°.

On the other hand, matte surfaces with less than 10
gloss units (at 60°) should be measured at the 85°
geometry.

28

Measurement techniques

9.2 Anodized aluminum and other metal surfaces

The measuring unit is equipped with an extended
measuring range for measuring samples with a very
high reflectance.

The reflectance of non-metallic surfaces increases
with the angle of incidence. The reflective properties of
metals do not always behave in this manner. Because
of double reflection, the light is partially reflected on
the coating and partially on the metal underneath. For
a complete understanding of the reflective properties
of such surfaces, it is recommended to measure them
at all geometries.

In addition to the reference to a black glass standard
(gloss units), it is also common in the area of metals
to relate the reflectometer value to the amount of
irradiated light and to express it as a % (reflectance).
You can select this in the Scale menu.

Notes

Proper measurements are only possible on level
surfaces.

Measurements on dirty, scratched or otherwise
distorted areas of the test specimen are not meaning­ful except as a way of determining the degree of such
imperfections by means of a gloss measurement.

Since it cannot be assumed that the gloss capacity is
not constant over the entire surface of the test
specimen, the reflectometer value can be measured
at several different places and the standard deviation
can be determined.

If the sample exhibits structures or directionally
dependent gloss properties, the structural features
and the direction of the incident light should be
specified for the measurement in the test report.

Samples that must be measured several times over
the course of an examination (for example weathering
samples) should be marked accordingly to ensure
that the measurement is made at the same point
during repeated tests.

29

10. Measurement Modes

You can select different types of measurement in
the Mode menu. The mode that is activated is
identified by a check mark.

10.1 Sample mode

Single measurements can be performed without
statistical evaluation in Sample mode.

The results can be saved and compared with a
standard (refer to Memory or Difference).

When Memory is turned on, a name is suggested
after every measurement. You can confirm this
name directly or change it.

If you would like to delete the last measurement,
press the scroll wheel and select the appropriate
menu item.

Measurement Modes

30

10.2 Statistics

You can make multiple measurements with each
sample in Statistics mode. These measurements
will be evaluated statistically and displayed.

The results can be saved and compared with a
standard. These functions must be previously
activated (refer to Memory or Difference).

Measurement Modes

When Memory is turned on, a name is suggested
after all measurements of a sample (block). You can
confirm this name directly or change it.

When the Statistics function is turned on, additional
functions are available depending on the context
after you press the scroll wheel.

31

Measurement Modes

10.2.1Number of measurements

You can adjust the number of measurements per
sample or per block with this option, from 2 - 99.

You can find this value in the measurement display
by looking for “n=” after the forward slash. The
number of measurements (which increases by one
each time a measurement is performed) appears
before the slash.

10.2.2Display

In the Statistics measurement display, you can
assign the following data freely to three columns:

Value:

Last value to be measured

Mean value:

Arithmetic mean of the sample (block).

Maximum:

Highest measurement value of the sample

Minimum:

Lowest measurement value of the sample

Range:

The difference between the maximum and minimum
value.

32

Measurement Modes

Std. Dev.:

The standard deviation of the sample

Difference*:

The difference between the sample and a target
value.

Pass/Fail*:

Pass is displayed if the sample value falls within the
specified limits, or Fail if it falls outside.

wheel to open the Continuous submenu.

The longest measurement interval possible is 9
seconds, the shortest 0 seconds for continous
measuring.

10.4 Basic mode

The selection options are limited to the most
essential in Basic mode. This also greatly simplifies
operation in this mode.

You can select geometry and perform calibration. In
addition, all functions in the Setup menu item are
available.

Basic mode is useful if you want to interrupt a
series of measurements and quickly perform some
other measurements in the middle without leaving
the series of measurements.

Once these other measurements are complete, you
can use

to return to the point where you interrupted the
series of measurements.

12. Memory

To save measurement values, you must activate the
Memory function before measuring or else select or
create a memory. Up to 999 measurements can be
stored. A fixed memory area is already created for
each geometry or combination (e.g. M60°). These
memory areas cannot be deleted. A total of 50
memory areas can be created.
The Memory function can be used for sample mode,
Statistics and Continuous measurements. The
layout of the memory is such that the measurement
mode and the standard can be changed within a
memory area, but not the geometry.

12.1 Memory

You can use this function to turn saving on or off. A
check mark indicates if the function has been
activated.

Turning on Memory automatically selects the area
in memory that is predefined for the currently set
geometry (for example M20°60°).

When you press operate to start a reading, you are
asked to enter a name for this memory.

12.2 Select memory

All available areas of memory are listed in this
menu, beginning with the one that is predefined.

The number of measurements saved for each area in
memory is shown on the right.

Select the appropriate memory area with the scroll
wheel and activate the selection by pressing mode.

This automatically turns on Save and switches the
geometry if necessary (if the selected memory area
is defined for other geometries than what was
previously set).

Difference measurement and Pass/Fail

13. Difference measurement and Pass/Fail

You can compare the readings of samples with the
value of a previously measured or saved standard.
For saved standards, you can also display whether
the test specimen falls within the limits (Pass) or
outside (Fail).

Up to 50 standards can be saved. They are stored in
a separate area of memory. For each geometry you
can determine:

- A target value

- Maximum and minimum for Pass/Fail,
see Create standard or Change standard.

13.1 Difference

You can use this menu option to turn Difference
measurement on or off. A check mark indicates if
the function is active.

When you turn on Difference, the last standard to be
used is automatically selected.

continue.

13.2 Measure standard

We recommend to perform several readings on the
standard with Statistics turned on.

Memory must be activated to store the measured
standard. Otherwise it will be temporary hold until
another standard is measured.

Activate “Measure standard” and perform the
measurement with operate. With memory on, a
window appears after the last reading where you can
enter the standard’s name.

If you inadvertently select a name that has already
been used, a message will appear in the display
and the arrow will jump back to the first position of
the name.

Errors and warning messages

19. Errors and warning messages

Memory full Transfer the content of memory to a PC and then

delete the contents of memory.

Reference memory full A maximum of 50 references can be saved. It may

be necessary to delete old references.

You will also find an error number for the following messages in the Calibration/
Status menu to provide support for diagnostics:

Tolerance Generally occurs only with major changes in
Error 01 climatic or weather conditions. The deviation was

successfullycompensated for by calibration and
correct measurements are still possible. You should
still recalibrate the device as soon as it is operating
in normal climatic conditions again. However if a
change in climate cannot be considered as the
cause of the problem, you should check whether the
standard is clean.

Please call Service Autodiagnosis has determined an impermissible

Service (invalid) deviation in the measurement signal
that cannot be remedied by recalibrating.

Error 02 Generally occurs when there is a significant amount

of dirt or dust on the standard or optics. First try to
clean the standard. You should only have the optics
cleaned by our Customer Service department, for
example as part of a yearly recertification.

Error 03 Defect in the electronics or operating error. First

check whether the standard is clean and whether

the device is properly snapped into the holder.
Error 04 Defect in the lamp or electronics.
Error 05 Defect in the electronics.

Please observe the instructions on cleaning standards in the section on
Calibration.

the sample used for all
measurements?

Yes. It may help to test
the calibration with an
additional standard if
one is available.

Calibration correct:

Is the test surface
completely even and
does the measuring
device have good
contact with the
sample?

Yes: Device defective

No. Check how high the deviations are on

the sample itself.

Calibration not correct:

Recalibrate and clean the standard if
necessary.

No:

In this case, major deviations are possible.

Please contact our Customer Service
department.

Do not attempt to make any repairs yourself! If a malfunction occurs on your
measuring device, our Customer Service department will be happy to help you
as quickly as possible.

20. Cleaning and maintenance

• Do not insert any objects into the measurement

aperture for cleaning. The instrument could get

damaged - affecting a proper and safe operation.

• The instrument housing is resistant to a number

of solvents, but cannot be guaranteed to withstand

all chemicals. You should therefore use a soft,

moist cloth for cleaning. For cleaning excessive dirt,

use ethanol or cleaning alcohol. Do not use any

acetone!

• Cleaning standards

The accuracy of the measurement can be

significantly impacted by using dirty or damaged

standards.

Since the surfaces of the standards are highly

sensitive, cleaning must be undertaken with great

care.

To clean standards, use a new lint-free cloth, dust-

free lens paper or an optical cloth.

Apply only slight pressure as you clean and make

certain there are no large particles stuck in the cloth

that could damage the surface. Do not use any

acetone!

For dirt that is difficult to remove, use an optical

cloth dipped in liquid. Then wipe the surface with a

dry optical cloth.

Exact calibration is not possible unless the

standard is in perfect condition. If the condition of

the standard seems doubtful

because of its appearance or measurement errors,

we will be happy to check it for you.
