haze-gard plus is a stationary
instrument designed to measure the
appearance of glass and of films,
packaging and parts made of plastic
and other transparent materials.
The specimen surface is illuminated
perpendicularly, and the transmitted
light is measured photoelectrically,
using an integrating sphere (0°/diffuse
geometry). The spectral sensitivity
conforms to CIE standard spectral
value function y, under standard light
C resp. A.
Three parameters:
s TOTALTRANSMITTANCE
s HAZE
s CLARITY
permit visual appearance to be in
characterized fully and objectively.
haze-gard plus sets new standards

ments. Aside from its speed and ease
of operation, it also offers the follo-

The instrument chassis is resistant to
a number of solvents, but cannot be
guaranteed to withstand all
chemicals. Use only a soft, damp
cloth for cleaning. A little rubbing al-
cohol or mild soapsuds may be used
to remove stubborn dirt.
Clean the front lens of the clarity port
only with a soft, lint-free cloth (pre-
ferably a damp optical wipe).
NEVER clean the interior of the
detector sphere (haze port)!
If the instrument malfunctions, do not
attempt to repair it yourself. Our Cu-

WARM-UP
Only about 2 minutes are needed for
warm-up.
As soon as the instrument has
completed the self-diagnosis and
status displays, it immediately goes
into the mode that was active at
the last shutdown. It is now ready
for operation. Before you can take
measurements after starting the
instrument for the first time, it must
be calibrated (see Chapter 5).

4. Operation
Select the parameter you want to
measure.
By pressing one of the three
buttons you can either switch bet-
ween parameters (in Continuous
Mode), or add a parameter to those
you have already chosen. Pressing
the button a second time displays this
parameter by itself.
Set the specimen at the appropriate
port.
Haze port (right side): For
transmittance and haze.
Clarity port (left side): For clarity.
Check for possible surface defects
such as scratches or fingerprints.
The specimen must lie flat during
measurements.
Start the measurement by pressing
the <operate> button or the foot
switch.

ment ports (when multiple parame-
ters have been selected). Move the
specimen to the appropriate port and
start the measurement by pressing

State-of-the-art technology and the
reference-beam principle mean that
calibration is needed only infrequently.
We recommend a calibration interval
of two months.

on the display (for example, after
stored calibration values have been
modified).
To ensure accurate calibration, use
only original standards from
BYK-Gardner.
Do not touch the reference surface.
Protect it against scratching.
Even with careful treatment, ambient
conditions may alter a standard’s va-
lues over time. For that reason, have
Customer Service check your stan-
dards regularly (once a year) against
primary standards.
Make sure the values displayed du-
ring calibration match the data for the
standards you use, in order to avoid
mixing up or accidentally changing
the calibration values (see Section
5.3).
To calibrate:
CAUTION: Make sure the
calibration standards are clean
and free from scratches!

Now perform calibration for clarity.
Place the clarity standard at the clari-

If the calibration procedure is
cancelled with SET-UP, the last
calibration in effect remains valid.
This concludes calibration. The
instrument goes to the measuring
mode that was active before the
calibration.

Note: If fluctuating or obviously
wrong values are displayed after
calibration, repeat the calibration.
This symptom means the haze port
was either improperly covered (for
the dark measurement) or partially
still covered (for the bright
measurement) during the
measurements.

5.1 Additional Standards for
Monitoring Test Equipment
To check proper operation of the in-
strument, measurements with special
test standards should be performed
at regular intervals (about once every
three months). The appropriate test
standards are listed in the Ordering
Guide.
The displayed readings should fall
within the specified values for the
standard. If they do not, check that
the standard was clean and that the
device was properly calibrated. If
cleaning the standard and recalibra-
tion do not correct the error, please
contact Customer Service.
5.2 Cleaning the Standards
Calibration with a dirty or damaged
standard may severely affect the
accuracy of measurements.
Standard surfaces are very delicate.
Be very careful when cleaning them.
Use a fresh, soft cloth, and wash
the standards in running or standing
cold water. Do not apply a
scrubbing action or heavy pressure.
Make sure no large particles that
might damage the surface adhere to
the cloth.
Do not use aggressive cleaners
like solvents, rubbing alcohol,
trichloroethylene, benzine, or strong
alcohols, acids or lyes. Most chemical
cleaners or polishes will cause
damage.
To remove stubborn dirt, add a little
household dish detergent to the
water. Rinse with distilled water.
Dry with compressed air and blow
off any dust or lint.
Never rub the standard dry!
The rubbing action may cause
scratches from surface dust.
Precise calibration is possible only
with flawless standards. If visual
appearance or measurement errors
suggest that a standard is compro-
mised, we’ll be glad to check it.
