When the abdominal pressure reaches the set value, gas feeding is
stopped. When the abdominal pressure is lowered 1 mmHg below
the set value, gas feeding is stopped.
(1) Abdominal pressure display bar graph The number of lighting
is determined by the ratio of the abdominal pressure to the set
value. 7 green lamps with 100%, 0 lamp with 0%, and the
number changes with the same ratio between these values.
With an over-pressure, three red lamps light with the set
value + 4.5 mmHg. The set value is shown flickering.
(2) Abdominal pressure display (7-segment red LED)

(3) Set pressure display (7-segment green LED)

The set pressure is displayed in green.
(1) Abdominal pressure display bar graph
All LEDs up to the abdominal pressure are light in green. If
the set value is exceeded, it is light in red.
(2) Abdominal pressure display
The abdominal pressure is displayed in red.
(3) Abdominal pressure measurement error, after reaching the
abdominal pressure (± 2.7 mmHg)
3-25 mmHg in 1 mmHg units
The setting is changed by the abdominal pressure control switch.
Setting is possible in a range of 3 to 25 mmHg.
Each time the switch is pressed, 1 mmHg is changed.
When changing from 20 mmHg to 21 mmHg, hold the
switch pressed for 3 seconds or more.
The set value is stored when the power is turned off. If a pressure
of 21 mmHg or higher is set, it is stored as 20 mmHg.)
The relief mode ON/OFF is changed when the reset switch is held
pressed for 3 seconds or more immediately after the power switch
is turned on. When the relief mode is ON, the relief mode lamp
lights.
When the abdominal pressure rises 5 mmHg over the set value,
gas feeding is stopped and the following takes place.
(1) An audible alarm is emitted and the excessive abdominal
pressure alarm lamp is lit.
(2) When the condition (1) continues for 10 seconds or more,
automatic suction takes place. When the abdominal pressure
is lowered to the set value, suction is finished.
(3) When the relief mode is ON and the abdominal pressure rises
5 mmHg over the set value, the relief valve is opened to relief.
If the relief mode is OFF, relief is not performed.
When the tube is obstructed or gas is fed to a very narrow cavity
such as hypodermic space, gas feeding is interrupted and the tube
obstruction alarm lamp is lit with an audible alarm until it is
released.
