7calibration – ALTANA Micro-Haze Plus User Manual

Page 27

A haze calibration is not required
before each measurement. It
should, however, be renewed
regularly (e.g. on a weekly basis).
To do so, remove the measuring
unit from the gloss holder and
insert it into the haze holder. Start
the calibration by pressing the
operate button.

Please ensure in this case as well
that the displayed values corre-
spond to those printed on the pro-
tective holder. After approximately
3 seconds the calibration is
completed and the measuring unit
can be removed from the holder for
performing measurements.

7.1 Calibration Standards

Calibration with a dirty or damaged
standard will seriously impair the
accuracy of the measurements.

The standard is very sensitive and
must be protected from damage
and dirt. You should avoid touching
its surface.

Even when the calibration standard
is handled carefully, its value can
be altered by environmental
influences over the course of time.

It is thus advisable to check the
instrument against an additional
reference standard at regular
intervals.

You should also have the
standards checked by the
manufacturer at yearly intervals
(holder standard or secondary
standard).
