Safety
The meter was developed for work in the field and in the laboratory.
We assume that, as a result of their professional training and
experience, the operators will know the necessary safety precautions
to take when handling the chemicals of photometric test sets.
The personnel responsible for the commissioning, operation and
maintenance must have the necessary qualifications for this work. If the
personnel do not have the required skills they have to be instructed.
Furthermore, it must be ensured that the personnel read and
completely understand the present operating manual.
Important safety instructions are highlighted in this operating manual.
They are indicated by the warning symbol (triangle) in the left column.
The signal word (e.g. "Caution") indicates the level of danger:
CAUTION
indicates a possibly dangerous situation that can lead to slight
(reversible) injury if the safety instruction is not followed.
NOTE
indicates a possibly dangerous situation where goods might be
damaged if the actions mentioned are not taken.
CAUTION
Danger of eye damage by visible and invisible LED radiation. In
the cell shaft there are light emitting diodes (LED) of the 1M class.
Do not look at the radiation using optical instruments. With
normal, authorized use there is no hazard.
Display and socket field
