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 15mmHg and a nominal gas flow of 3l/min.
5. Use the syringe to create pressure between 27mmHg and 30mmHg, indicated
on the manometer. Start insufflation: Press the
START
button. An acoustic sig-
nal is emitted (for 5seconds) and the display depicts
Overpressure
while the
pressure exceeds 18mmHg (measured with external manometer).
6. Reduce the pressure. The warning ends when the pressure falls below
19mmHg (nominal pressure plus 4mmHg). Stop insufflation: Press the
STOP
button.
7. Select a nominal pressure of 29mmHg.
8. Use the syringe to generate a pressure of at least 31mmHg, which is indicated
on the display. Start insufflation: Press the
START
button. An acoustic signal is
emitted with a pressure of more than 30mmHg and the display depicts
Max-
imum Insufflation Pressure Reached.
9. Reduce the pressure. The warning ends when the pressure falls below
30mmHg. 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 15mmHg and a nominal gas flow of 10l/min.
3. Use the syringe to generate a pressure of at least 18mmHg, which is indicated
on the manometer. Start insufflation. The venting valve is activated with a
pressure of more than 18 mmHg (for 3 seconds).
