8.1 Dismounting
WARNING!
Physical injuries and damage to property and the
environment caused by incorrect interpretation of the
pressure display
1. The pointer of a damaged instrument, despite high
pressure, can still stand at zero accidentally.
2. As a consequence of the scale graduation of the
high-pressure gauges, despite the display values being
below the first scale marking, very high pressures can still
exist in the instrument. Example: With a scale range of
0 ... 4,000 bar, the first scale marking already has a value
of 100 bar.
