5.1 Transport

Check the dierential pressure gauge for any damage that may have been

caused by transport. Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport (e.g.

change in installation site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage

Storage temperature: -20 ... +60 °C

In order to prevent damage, the following points should be noted for the

storage of the pressure gauges:

■

Leave the pressure gauges in their original packaging

■

Following any possible removal of the measuring instruments, e.g. for testing,

the instrument should again be stored in its original packaging

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapour, dust, humidity and corrosive gases

medium is hazardous to health, e.g. caustic, toxic, carcinogenic,

radioactive, etc.
