• Repeated testing PS >0.5 bar
Pipelines with PS >0.5 bar must be subjected to a pressure test
every 10 years. Pipelines with DN > 25 must be subjected to a
main test under operating conditions every 2 years.
• Repeated testing PS <=0.5 bar
Pipelines with PS <=0.5 bar must be subjected to a main test
every 10 years.

1. Edit values: [Edit].
2. Enter values. [▲], [▼] and sometimes [◄], [►] → [OK].
Carrying out a pressure test
1. Build up test pressure (target) manually with the test pump or a
compressor at the connection provided.
2. Start measurement: [].
- Zeroing starts (5 s)
Option
> End stability time early: [Next]
> End measurement period early: [Next]
- Measurement is cancelled.
