Tightness Test
The "Tightness Test" acc. to DVGW – TRGI Process Instructions G
600 at pipes (operation pressure up to 100 hPa) is deposited as a
measurement routine in the ecom-B. Proceed as follows:
1. Connect the ecom-UNO to the connection AUX of the ecom-B.
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 pressure +/- 10%" during stabilization time, so the measure-
ment will start).
8. Once the measurement time is over, the result is displayed and
can be printed (IR printer required) by pressing <Print>.
9. If the menu "Tightness Test" is selected again, so the result can
be called up with "No" / <Enter> (as long as the ecom-B is on) or a
new measurement can be started with "Yes" / <Enter> (switching
from "No" to "Yes" with cursor keys <Up/Down>).
