Tightness Test

The „Tightness Test“ acc. to DVGW – TRGI Process Instructions G
600 by pipes (operation pressure up to 100 hPa) is deposited as a
measurement routine in the ecom-EN2. Proceed as follows:

1. Connect the ecom-UNO to the connection AUX of the ecom-EN2.

2. Close the conduit with a suitable adapter (test stopple, high-
pressure stopple or one-pipe counter cap).

3. Connect the components as described before.

4. Scroll with cursor keys <Up/Down> to the menu „Tightness
Test“. Activate with <Enter>.

5. Create the pre-adjusted test pressure with the air pump (the unit
beeps as soon as the pressure level is achieved).

6. Interrupt the connection to the air pump (switch-off the ball valve).

7. Wait for stabilization time (if the pressure remains in the range
„test pr/- 10% during stabilization time, so the measurement
will start).

8. Once the measurement time is over, the result is displayed and
can be printed by pressing <Print>.

9. If the menu „Tightness Test“ is selected again, so the result can
be called up with <F4> (as long as the ecom-EN2 is on) or a new
measurement can be started with <F1>.
