Important Notesfor Measurement and Calibration:

Do not hold themeter in the hand during measurement and calibration.

Glass vials andcaps must be cleaned thoroughly with deionised water after each measurement.Minor residuals can cause errors.

The outside of thevial must be clean and dry, before starting the test. Wipe the vial with alint-free cloth to remove fingerprints or waterdrops.

If the vial hasminor scratches or scuffs, add a few drops of silicone oil to outside of thevial. Wipe with lint-free cloth.

For the low turbidity samples (0 to 200NTU), we recommend that you use the same be aligned with the arrow on the meter

To avoid errorsfrom ambient light interference, do not use the meter in bright sunlight.Always close the light shield lid during measurement and

Calibration

Avoid spillage of water i`n the sample chamber.It may cause damage the meter
