6. SECURITY
The spectrophotometer must be used by previously qualified staff that knows how the
equipment works thanks to the user manual.
You should put the spectrophotometer in a horizontal plane schart chart, having a
safety area of at least 30 cm per side.
Do not place the spectrophotometer near any warm supply (burners, blowlamps, etc),
nor expose it directly to the sun. Avoid vibrations, dust and dry environments.
When you are not using the spectrophotometer for a long period of time please make
sure it is unplugged in order to avoid possible accidents.
It is essential to have the equipment switched off and unplugged from the net before
cleaning, checking components or replacing any piece (e.g. replacement of a fuse).
Never try to repair the spectrophotometer by yourself, since you will lose the warranty
and may provoke damages to the general operating system or the electrical installation,
as well as injuries to the people that usually handle the equipment (burns, hurts…).
Try not to spill any liquid on the control panel, though it is properly insulated. In case
you have any doubts do please immediately unplug the spectrophotometer (see
Maintenance
).
Made under the European regulations for electrical security, electromagnetic compati-
bility and security on machines.
