2. Safety measures
The instrument has been tested for the experiments and intended purposes documented in
the Operating Instructions. However, this does not absolve you from the responsibility of
performing your own tests of the product supplied by us regarding its suitability for the
methods and purposes you intend to use it for. You should therefore observe the following
safety measures.
Measures for your protection
– Ensure that you plug the power cable supplied into a socket which is
grounded! A technical defect could be lethal in the absence of grounding.
– Switch the instrument off and disconnect the power cable if you change
blown fuses! An electric shock could be lethal.
– Do not work in a hazardous area! The housing of the refractometer is not
gas tight (explosion hazard through spark formation, corrosion by gas
diffusion into the instrument).
Measures for operational safety
– Do not add samples with hard objects made of glass, metal or ceramics!
They could damage the prism.
– Clean the prism immediately after a measurement of strong bases! These
could attack the prism.
– Use only fuses of the specified type if you need to change them!
