4.3. Preliminary check
The preliminary check acc. to DVGW – TRGI Process In-
structions G 600 by pipes (operation pressure up to 100
hPa) is registered as a measurement routine in the
ecom-DP.
Proceed as follows:
1. Close the conduit with a suitable adapter (part of
ecom-DPK).
2. Connect the components a described in ecom-DPK
manual.
3. Scroll with <UP/DOWN> until the menu „Preliminary
check". Activate with <OK>-Taste.
4. With the compressed-air pump create the pre-adjusted
test pressure (the unit beeps as soon as the pressure
level is achieved).
5. Interrupt the connection to the air pump (switch-off the
ball valve).
6. Wait for stabilisation time (if the pressure remains in
the range „test pressure +/- 10% during stabilisation time,
so the measurement time will start).
7. Once the measurement time is over, the result is dis-
played and can be sent to the IR printer (option) thus
pressing <F2> (Print).
8. If the menu „Preliminary Check" is selected again, so
the result can be called up with <F1> (as long as the
ecom-DP is on) or a new measurement can be started
with <OK>.
