1.1 Authorized use
The authorized use of the meter consists exclusively of the measure-
ment of dissolved oxygen and temperature of liquid media in a field and
laboratory environment.
The technical specifications as given in chapter 3 TECHNICAL DATA must
be observed. Only the operation and running of the meter according to
the instructions given in this operating manual is authorized.
Any other use is considered unauthorized.
1.2 General safety instructions
This meter is constructed and tested in compliance with the IEC 1010
safety regulations for electronic measuring instruments.
It left the factory in a safe and secure technical condition.
Function and
operational safety
The smooth functioning and operational safety of the meter can only be
guaranteed if the generally applicable safety measures and the specific
safety instructions in this operating manual are followed during opera-
tion.
The smooth functioning and operational safety of the meter can only be
guaranteed under the environmental conditions that are specified in
chapter 3 TECHNICAL DATA.
If the meter was transported from a cold environment to a warm envi-
ronment, the formation of condensate can lead to the faulty functioning
of the meter. In this event, wait until the temperature of the meter
reaches room temperature before putting the meter back into opera-
tion.
Caution
The meter is only allowed to be opened by authorized personnel.
