Correct filling of the vial:
6. Always perform zeroing and test with closed vial cap.
7. Bubbles on the inside wall of the vial lead to incorrect measurements. To prevent this,
remove the bubbles by swirling the vial before performing the test.
8. Avoid spillage of water in the sample chamber. If water should leak into the instrument
housing, it can destroy electronic components and cause corrosion.
9. Contamination of the lens in the sample chamber can result in errors. Check at regular
intervals and – if necessary – clean the light entry surfaces of the sample chamber using
a moist cloth or cotton buds.
10. Large temperature differences between the instrument and the environment can lead
to errors – e.g. due to the formation of condensation in the area of the lens or on
the vial.
11. To avoid errors caused by stray light do not use the instrument in bright sunlight.
