Safety instructions

This operating manual contains special instructions that must be followed 
during the operation of the  D.O. sensor.

Always keep this operating manual in the vicinity of the sensor.

Special user

qualifications

The membrane cap of the D.O. sensor is filled with a small amount of an 
alkaline electrolyte solution. All maintenance work that requires dealing with 
the electrolyte solution must only be carried out by persons who know how to 
safely deal with chemicals.

Operating manual

Note

The membrane cap that is mounted on the sensor for delivery serves mainly 
as a transport protection. Depending on the duration of the transport and 
storage period, it may have a shortened operational lifetime. If the measuring 
system cannot be calibrated (error message of the instrument), please 
proceed according to section R
