General use of buttons
The functions of the single buttons are only activated when you release the button. When a
parameter is displayed, first the parameter name appears, for example
FLO
for flow
AL.HI
for
high oxygen alarm etc. for about 1 second. Then the actual value is displayed.
With the button it is easy to scroll between
FLO
,
AL.HI.
and
AL.LD
and return to the output of
the actual O
2
(20.9)
No matter which parameter is currently displayed, the device automatically returns to display
the actual O
2
when there has been no activation of any button for about 5 seconds (the
sensor flow can be read constantly. See "Indication of sensor flow" on page 13 .
Start and stop of measuring
In the set-up menu it is selected whether the measuring is controlled via the

button, via
external pump control signal, button as well as external control signal or if the measuring is
always activated. If only an external control of measuring has been chosen or the measuring is
always activated, the button

is inactive. If either of the two other set-up possibilities has
been chosen, the measuring can be started and stopped using the button

.
1. Press

and the measuring starts. As soon as the measuring has started, the measured O
2
concentration is read out on the display.
2. Press

again and the measuring stops and the displays turns off (only % will be lit).
External/manual start and stop of measuring
If an external and manual control of measuring has been chosen in the set-up menu, the
measuring will start when the external measuring control signal is set to ON and stop when
the signal is set to OFF. It is only when the external control signal is changing condition that
the measuring starts/stops. Every time the

key is pressed the conditions change, meaning
that if the measuring has been started by the external control signal the measuring stops
when

is activated. Now measuring can only be started by the external signal if signal is set
to OFF and the ON again.
