2.1 Authorized use
This instrument is authorized exclusively for turbidity mea-
surements in the laboratory.
The technical specifications as given in chapter TECHNICAL
DATA, must be observed. Only the operation and running of
the measuring instrument according to the instructions given
in this operating manual is authorized. Any other use is con-
sidered unauthorized.
2.2 General safety instructions
This instrument left the factory in a safe and secure techni-
cal condition.
Function and oper-
ating safety
The smooth functioning and operational safety of the mea-
suring instrument can only be guaranteed if the generally
applicable safety measures and the specific safety instruc-
tions in this operating manual are followed during operation.
The smooth functioning and operational safety of the mea-
suring instrument can only be guaranteed under the climatic
conditions specified in the chapter TECHNICAL DATA.
If the instrument was transported from a cold environment to
a warm environment, the formation of condensate can lead
to the faulty functioning of the instrument. In this event, wait
until the temperature of the instrument reaches room tem-
perature before putting the instrument back into operation.
