Safety
Safety information Safety instructions point out dangers:
NOTE
indicates a possibly dangerous situation where goods might be
damaged if the actions mentioned are not taken.
Safe operation
Authorized use This meter is authorized exclusively for carrying out the following measure-
ments in the laboratory:
Analysis of substances in water and aqueous solutions
using round cells
Concentration measurement
Absorbance and transmission measurement
Only the operation and running of the meter according to the instructions and
technical specifications given in this operating manual is authorized (see
TECHNICAL DATA, page 20).
Any other use is considered unauthorized.
Display and socket field
Display The graphic display shows all information of the current measurement in the
measured value display. The illumination enables to read the display even in
the darkness.
WARNING
indicates a possibly dangerous situation that can lead to se-
rious (irreversible) injury or death if the safety instruction is
not followed.
CAUTION
indicates a possibly dangerous situation that can lead to
slight (reversible) injury if the safety instruction is not fol-
lowed.
CAUTION
Danger of eye damage by visible and invisible LED radiation.
In the cell shaft of the Turb 430 IR there are light emitting di-
odes (LEDs) of the 1M class.
Do not look at the radiation using optical instruments.
With normal, authorized use there is no hazard.
