Check the instrument for any damage that may have been caused.
Obvious damage must be reported to the manufacturer immediately.
WARNING!
Physical injuries and damage to property and the environment
caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature
and under high pressure or vacuum may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
▶
Wear the requisite protective equipment.
The digital pressure gauge is designed for operation under the following ambient
conditions (IEC 61010-1):
■
Overvoltage category II, pollution degree 2
