of the measuring device marked with “bar” using a pressure
hose with a pneumatic quick coupling NW 5 and start the
measurement. Using
(CONTINUE)
, the instruction is given to
establish the test pressure plus 10 %. The measuring proce-
dure cannot be continued until the required pressure is estab-
lished.
Start the stabilization phase.
The stabilization phase can be terminated manually and you
can switch to the measurement using
(CONTINUE)
.
After the stabilization period has ended or using
(CONTINUE)
,
the instruction is given to reduce the pressure to the test
pressure.
The test time begins after reducing the pressure to the test

(CONTINUE)
. The pressure in the sewage line at
the beginning of the measurement, the current pressure, the
pressure difference and the already elapsed test time are
shown.
After the test time has ended or
(CONTINUE)
, the result is
shown with test time, pressure in the sewage line at the be-
