After selecting the menu using
a selection
can be made with a radio button between a
color measurement and a comparison with a
color reference (if a color reference has already
been defined via the color analysis menu). A
sample name can be entered in the title field.
After selecting the color measurement, the color
type to be measured can be selected; the light
source and observer fields are automatically
filled out. These can also be manually changed
at any time. However, in this case, the selection
of the color number automatically returns to the
setting CIE L*a*b. Confirming with
opens the
measurement menu. After measuring the zero
solution and measuring the color solution, the
result is displayed in the measurement window.
The menu for the color analysis can be accessed
by calling up an individual “color measurement”
result in the measuring device memory and then
pressing the
icon.
NTU check
The

II enable a warning of interfering turbidity when measuring
a test in the 16 mm round cuvette. The NTU check is enabled as a factory preset. The
nephelometric turbidity is determined at the same time as the measurement by measuring at
860 nm at a 90° angle.

The NTU value is displayed together with the
result. If the warning limit of 10 NTU is exceeded,
a warning is displayed and the result is shown
in red (Fig. 15. The measured turbidity value is
stored together with the result.
