Important information for pressure measurement
Temperature fluctuations and positional changes have an effect on
the accuracy of pressure measurements:
• The entire measuring system must be adapted to the ambient
temperature and to the temperature of the pipe system to be
tested.
• The temperature of the measuring system and the pipe system
must remain stable during measurement.
• The position of the measuring system must not change during
measurement.
