10.4 Pressure Monitoring Test (in Standard Operating Mode)
See also Chapter Technical Data [}67].
1. In the user menu activate the
Venting Valve
.
2. Go to the OP Screen.
3. Set the Standard operating mode.
4. Select a nominal pressure of 15mmHg and a nominal gas flow of 3l/min.
5. Use the syringe to create pressure between 27mmHg and 30mmHg, indicated
on the manometer. Start insufflation: Press the
START
button. An acoustic sig-
nal is emitted (for 5seconds) and the display depicts
Overpressure
while the
pressure exceeds 18mmHg (measured with external manometer).
6. Reduce the pressure. The warning ends when the pressure falls below
19mmHg (nominal pressure plus 4mmHg). Stop insufflation: Press the
STOP
button.
7. Select a nominal pressure of 29mmHg.
8. Use the syringe to generate a pressure of at least 31mmHg, which is indicated
on the display. Start insufflation: Press the
START
button. An acoustic signal is
emitted with a pressure of more than 30mmHg and the display depicts
Max-
imum Insufflation Pressure Reached.
9. Reduce the pressure. The warning ends when the pressure falls below
30mmHg. Stop insufflation: Press the
STOP
button.
10.5 Venting Valve Test
See also chapter Pressure Sensor Test (Standard Operating Mode) [}59].
1. In the user menu
Venting System
, switch the venting system on (if setting
Veress Insufflation OFF
).
2. Select a nominal pressure of 15mmHg and a nominal gas flow of 10l/min.
3. Use the syringe to generate a pressure of at least 18mmHg, which is indicated
on the manometer. Start insufflation. The venting valve is activated with a
pressure of more than 18 mmHg (for 3 seconds).
