OPERATION
In the TEsT PREss. submenu
the arrow buttons and can be used to set the
test pressure within the limits –3,500 to +6,500 Pa in
5 Pa increments. If the arrow buttons are pressed for
longer than 1.5 s, the pressure value changes quickly.
F2 – chANGE
Change the “Test pressure”
parameter
In the sURFAcE submenu
the arrow buttons and can be used to set the
surface area between 0.1 and 2,000 m
2
in 0.1 m
2
increments. If the arrow buttons are pressed for
longer than 1.5 s, the surface area value changes
quickly.
F2 – chANGE Change the “Surface” parameter
Start the test by pressing the
sTART button (F3)
. The
current pressure in Pa and the volumetric flow in l/s
(with two decimal places) are displayed continuously.
The automatic mode controls the pressure to the pre-
defined test pressure. As soon as it is /- 5%
accuracy, the actual test time of 5 minutes begins. A
counter indicates the remaining test duration. This
counter is stopped if the test pressure leaves the
above-named tolerance range during the test.
The automatic test can be ended prematurely by
pressing the
sTOP (F3) button
. The measurement pe-
riod that has passed up to this time is then evalua-
ted. However, no statement is made as to whether
the test was passed or not, as it was not performed
in conformity with the duration of 5 minutes required
in the relevant standard (see EN 1507:2006 Clause
5.22).
If the leakage volume at the set test pressure is abo-
ve 36.0 l/s, the measurement is cancelled with the
following error message:
VOLUME FLOW TOO
LARGE! PLEAsE REDUcE
TEsT PREssURE!
If the leakage volume at the set test pressure is be-
low the measurement limit of 0.08 l/s, the measure-
ment continues, but a specific measurement value
cannot be determined. As a result “Leakage volume <
0.08 l/s” is then output.
