LC Display
The LC Display Fig. 12 /9 is the communication interface to the operator. It displays
the leak rates, the status report of the PHOENIX L300i, messages, warnings and
errors. With the soft keys no.1 to no. 8 various functions which are shown in the
display can be selected
START Button
Pushing the START Button Fig. 12/10 enables the PHOENIX L300i to start the
measure procedure. The measured leak rate is shown in the display. If the START
button is pushed again in measurement mode, the maximum leak rate indicator
(„hold“ function) is activated. This indicator shows the maximum leak rate since
„START“. By pressing the START-button again the „hold“ function will be started
again.
STOP Button
Pushing the STOP Button Fig. 12/12 interrupts the measure procedure. If the but-
ton is pressed longer the inlet is vented according to the conditions defined in the
menu Vent delay. See Chapter 3.10.1 to select the time parameters of the venting.
ZERO Button
Pushing the ZERO button Fig. 12/11 enables the zero mode. (see also Chapter
3.10.2)
When pressing ZERO the currently measured leak rate is taken as a background
signal and is subtracted from all further measurements. As a result the displayed
leak rate then is
After pressing ZERO (Fig. 13, t=1) the decreasing background is fitted to the
course (Fig. 13, t=2) automatically. When the measurement signal declines below
the saved background the underground value will automatically be equated with
the measurement signal. As soon as the measurement signal is increasing again
the saved decreasing value remains constant. Increasing of the signal are dis-
played clearly as a leak So it is possible to recognize leaks even when the signal is
decreasing rapidly.
