Likely Cause
For measurements with 11mm round
cells the adapter Z is required.

range.
The measured absorbance exceeds 3.5
Calculated concentration is higher than
999999

Electronic defect
The instrument sensors detects too
much ambient light.
The calculated result is negative
Error in the test database / user
database
The measured absorbance is above the
calibration range of the test
The measured absorbance is below the
calibration range of the test
Action
Insert the adapter Z into cell
compartment #2.
Press OK.
Dilute the sample or select appropriate
color scale.
Dilute the sample and repeat the
measurement

Remove the cuvette/sample cell from
the cell compartment.
Press OK.
Contact the manufacturer or a sales
representative and indicate the error
number
Reduce ambient light. (Avoid direct sun
light.)
Close the lid.
Check the concentration of the sample
Check the programming
