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 "Output 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.
