Performing the measurement:
✓ The pressure socket of the instrument must be free (i.e.
unpressurized, not closed).
1. Leakage Rate Test → [OK].
- Pressure zeroing.
2. Select parameter: [▲], [▼] → [Edit].
3. Set parameters or enter data: [▲], [▼] and partly [◄], [►] →
[OK].
4. Pressurize the system.
Once the pressure has built up, a stability time specified by
DVGW-TRGI 2008 should be observed to ensure that any
possible pressure fluctuations are not recorded in the
measurement.
The relevant standard provides more
detailed information.
- The stability time will run. After this the measurement phase
starts automatically.
> End stability time and measurement early: [Next].
- The readings are displayed when measurement has been
completed.
6.2.15.2. Main test
• Follow DVGW-TRGI 2008, worksheet G624.
• Pressure Absolute (parameter of measurement place)
must strictly be entered to obtain correct meas. views. If
this is unknown it is recommended to use the value
966hPa (corresponds with 1013 hPa barometric,
altitude 400m) To enter the values:
> [ ] → Measurements → [OK] → Gas Pipe Tests →
[OK] → [Main Test] → [Fold./Meas.] > [Options] →
Edit Measurement Site:
> Plug the connecting plug of the hose connection set
(0554 1203) into the flue gas socket and lock in place by turning
it slightly clockwise (bayonet lock).
