Over measuring range
The measured absorbance is above the
calibration range of the test
Dilute the sample and repeat the
measurement
Please check the lamp. The lamp output is too low
Check the lamp and replace it if
necessary
Too much ambient light!
Move device into shade
or close the lid!
The instrument sensors detects to much
ambient light.
Reduce ambient light. (Avoid direct sun
light.)
Close the lid.
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
with a longer path length
Unstable lighting conditions!
Fluctuating light conditions during the
measurement
Close the lid or place the Protective
Cover on the cuvette compartment (2)
