2.3
Special hazards
WARNING!
■
Use the CPG500 digital pressure gauge only with safe gases and liquids per
directive 67/548/EEC.
■
If it is obvious that safe operation of the instrument is no longer possible, the
instrument must be put out of operation and marked in order to secure it against
inadvertent use.
■
The measurement signal of the reference (or test sample) can be influenced by
massive electromagnetic irradiation and/or the indication of the signal could be
completely absent.
■
If the digital pressure gauge CPG500 is used in applications with oil as a pressure
medium, make sure it will not be used with flammable material or gases directly
afterwards since it can lead to dangerous explosions and danger to personnel
and machinery.
■
Digital pressure gauges should only be fitted or remored when the system is free
from pressure.
■
Observe the working conditions in accordance with chapter “3. Specifications”.
■
Always operate the pressure indicator within its overload limits.
