OPERATION
Manual test mode
This corresponds to automatic test mode, with the
exception that the test pressure must be adjusted
manually by changing the fan speed to the entered
target value.
After pressing the
start button (F3)
, the compressor
(fan) does not start automatically, but must be ad-
justed using the arrow buttons and to a speed
at which the preset pressure is kept within the limits
+/- 5 %. If the arrow buttons are pressed for longer
than 1.5 s, the compressor (fan) speed changes quickly.
The current pressure in Pa and the volumetric flow
in l/s (with two decimal places) are displayed con-
tinuously. In addition, a numerical value between 0
(speed = 0) and 4095 (maximum speed) appears in
the display
(5)
for orientation purposes and indica-
tes the speed of the compressor (fan). Whenever
the test pressure is within the tolerance window, a
countdown counter counts down from 5 minutes to 0.
The measurement ends after the time has expired or
by pressing the
sTOP (F3) button
.
The evaluation uses the average of the measured
values from the entire test duration. However, if the
test duration during which the test pressure was wi-
thin the tolerance range band is less than 5 min, as
with the automatic measurement, no statement is
made whether the test was passed or not, as it was
not performed in conformity with the standard for a
duration of 5 minutes.
The same options for recording the test exist for
manual test mode as for automatic mode. (See also
