8. Operation / Configuration / Adjustments
8.1 Leak testing
Before starting up, all pressure lines, fittings and other components of the
pressurized system circuit must be tested for leaks.
Test methods:
- pressure drop method
- shut off the line circuit, pressure drop observed on time
and / or
- method of blowing
- spraying relevant surfaces by means soap bubbles
medium - a possible blowing magnification is observed
8.2 Permissible vibration load at the mounting point

The instruments should always be installed in locations free from vibration.

If necessary, it is possible to isolate the instrument from the mounting point
by installing a flexible connection line between the measuring point and the
pressure gauge and mounting the instrument on a suitable bracket.

If this is not possible, the following limit values must not be exceeded:
Dry gauges: Frequency range < 150 Hz Acceleration < 0.7 g (7 m/s2)
Liquid-filled gauges: Frequency range < 150 Hz
Acceleration < 4 g (40 m/s2)
The liquid filling must be checked on a regular basis.
The liquid level must not drop below 75 % of the gauge diameter.
