Wait at least 5 seconds before switching the instrument on and
then off again at the main switch.
If the measuring water contains more than 20 mg/I CO
2
(carbonic
acid), incorrect evaluations cannot be excluded.
If the ion concentration is too high, it will lead to measurement
deviations.
Interfering ions: heavy metal with a content of 5 mg/l or more,
anions e.g. sulphate with a content of 240 mg/l or more and
a hardness above 80°dH.
Reagent consumption:
0.8 ml per assay
The coverage of a 500 ml bottle: approx. 500 assays
The concentration of influencing contents can be determined by
using our colorimetric TESTOVAL
®
test kit.
Careful handling of the instrument increases both its operational
reliability and service life! Therefore, carry out a visual inspection
at regular intervals as described below:
– Has the use-by-date of the indicator expired?
– Are the hose connections of the dosing pump free of leaks?
– Is there any air inside the dosing hoses?
– Are all the water connections free of leaks?
– Are the doors of the instrument closed properly?
– Is the instrument heavily soiled?
– Are the measuring chamber and the drain duct/drain hose
clean?
Trouble-free operation is only possible when maintenance is
carried out on a regular basis! For more information, please refer
