2. Connect the components a described in ecom-DPK
manual.
3. Scroll with <UP/DOWN> until the menu „Main

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).
