6.5.3 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-EN3. Proceed as
follows:
1. Connect the ecom-UNO to the connection AUX of the ecom-EN3.
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 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-EN3 is on) or a new measurement can be
started with <F1>.
The following adjustments can be made in the menu Pressure Tests / Setup for the procedure
