Cleaning
A clean optical measuring system is a basic prerequisite for determining precise measured values.
Therefore, clean the instrument regularly and immediately after it becomes dirty. Always power off the instrument
before cleaning it!
Use only the following items for cleaning:
• Ordinary lint-free cotton balls
• Ordinary lint-free tissues
• Ordinary disinfecting tissues
• Cotton swab
Mild soap suds as well as 70 % ethanol or isopropyl alcohol are suitable for cleaning. When used in the
professional sector (e.g., doctor’s offices), a mixture consisting of 1-propanol, 2-propanol and
glutaraldehyde (brand name “Bacillol plus”) is recommended.
Do not use any disinfectant sprays or tissues or cotton balls which are dripping wet as the liquid may
enter the instrument and damage it.
