16 Tap TEST to perform the measurement.
17 The measured value is immediately displayed.
Notes:
If the sample water contains further oxidizing agents, these will react like hydrogen peroxide
and contribute to the measurement result.
Make sure no hydrogen peroxide escapes while preparing the sample. The measurement must
be performed directly after sampling.
Do not clean glassware and equipment with household detergents, as these could greatly
reduce the measurement result. To prevent any contamination, the cuvette, lid and stirrer
should be stored in a 0.1 % sodium hypochlorite solution for one hour. Then rinse with distilled
water, thoroughly.
