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:
• total transmittance
• haze
• clarity
permit visual appearance to be
characterized fully and objectively.
haze-gard plus sets new standards
in transparency measurement
instruments. Aside from its speed
and ease of operation, it also offers
the following features:
• pen specimen area for small
and large products
• Automatic calibration and menu-
driven operation
• High accuracy and reliability
thanks to reference-beam optics
• Longterm calibration and self-
diagnosis
• Closed optics and electronics
• Ready to operate immediately
no lengthy warm-up needed
• Foot switch
• Internal statistics functions
• Memory to store readings,
PC interface, printer outlet
haze-gard plus conforms to the
standards ASTM D-1003 and
ASTM D-1044.

5. Calibration 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.
Calibration is also necessary:
• at the first startup
• in the event of a drastic change in
ambient temperature (for example,
after moving the unit to a new site)
• if "Please Recalibrate" appears 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 values over time. For
that reason, have Customer Service
check your standards regularly
(once a year) against primary
standards.
Make sure the values displayed
during 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!

5.1 Additional Standards for
Monitoring Test Equipment
To check proper operation of the
instrument, measurements with
special test standards should be
performed at regular intervals
(about once every three months).
The appropriate test standards are
listed in the rdering 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
recalibration 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.

Pressing the <operate> button
saves the new setting for the
standard value and returns you to
the "Change Calibration Value"
submenu. Pressing the <set up>
button rejects the change and
retains the old standard value.
These new values remain valid only
until the unit is switched off. When it
is switched back on, the old values
are restored.
The "Save Standard Values"
function serves to save the reset
standard values permanently, so
that they are retained even after the
instrument is switched off. If a
change has been confirmed with
<operate>, a recalibration is
necessary after exiting from the
"Change Calibration Value"
submenu.
Select the
standard you
want to change,
and confirm with

In the four-digit display, the last
