Main Test - TESTO 330 Instruction Manual

6 Using the product
Performing the measurement:
✓ The pressure socket of the instrument must be free (i.e.
unpressurized, not closed).
1. Leakage Rate Test
- Pressure zeroing.
2. Select parameter: [▲],
3. Set parameters or enter data: [▲],
[OK].
4. Pressurize the system.
- 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

> Plug the connecting plug of the hose connection set
(0554 1203) into the flue gas socket and lock in place by turning

→ [OK].
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.
• Follow DVGW-TRGI 2008, worksheet G624.
