Cleaning and care
The lens in the opening of the measuring sensor is the most
sensitive part of the appliance.
Be very careful when you have to clean it. In order to avoid
contamination with germs, the lens has to be rubbed after
every use with a soft cloth that has been moistened with
70% medical alcohol. The use of hygiene attachments is,
therefore, not necessary. After that, wait for at least
30 minutes before taking another measurement. Please
keep in mind that due to the evaporative cooling eff ect of
the alcohol, even the smallest amounts can falsify the result.
Clean the housing with a soft, slightly damp cloth. In the
case of more severe soiling a mild detergent can also be
added to the water.
