Please insert adapter Z.
For measurements with 11mm round
cells the adapter Z is required.
Insert the adapter Z into cell
compartment #2.
Press
OK
.
Color = ***
Spectrum locus outside the measuring
range.
Dilute the sample or select appropriate
color scale.
Absorbance > 3.5!
The measured absorbance exceeds 3.5
Dilute the sample and repeat the
measurement
Concentration too high!
Calculated concentration is higher than
999999
Dilute the sample and repeat the
measurement

Error
Too much ambient light!
Move device into shade
or close the lid!
The instrument sensors detects too
much ambient light.
Reduce ambient light. (Avoid direct sun
light.)
Close the lid.
Negative result!
The calculated result is negative
Check the concentration of the sample
No evaluation!
Error in the test database / user
database
Check the programming
Contact the manufacturer or a sales
representative
Over measuring range
The measured absorbance is above the
calibration range of the test
Dilute the sample and repeat the
measurement
Under measuring range
The measured absorbance is below the
calibration range of the test
If possible, select a test with a lower
measurement range or use a
cuvette/sample cell with a longer path
length
