Shutdown
at an output pressure of
>2.0
bar ±0.4 bar
Test setup
• The test specimen is connected to the power supply via a VIO electro-
surgical unit.
• The argon gas bottle is connected to the test specimen.
• With APC socket: The pressure gauge is connected to the gas output of
the APC socket. The VIO APC handpiece is electrically connected to the
APC socket.
• With FiAPC socket: The Test adapter FiAPC is connected to the FiAPC
socket. The pressure gauge is connected to the gas output of the test
adapter.
Test procedure
1. Press the Purge button. The gas flow generates a back pressure at
the gas output.
2. Check output pressure with the pressure gauge.
3. When an output pressure of 2.0 bar ±0.4 bar has been reached, the
test specimen must discontinue activation automatically and display
the warning "A-40".
Bottle pressure detection
APC
2 + VIO D
This test is performed in different ways depending on whether the APC 2
is connected to a VIO D or a VIO S electrosurgical unit.
Test setup
• The test specimen is connected to the power supply via a VIO D HF
surgical unit.
• The argon gas bottle is connected to the test specimen.
• The Testbox is connected to test specimen via the pressure sensor
connection.
• With APC socket: The VIO APC handpiece is electrically connected to
the APC socket.
• With FiAPC socket: The Test adapter FiAPC is connected to the FiAPC
socket.
IMPORTANT! From VIO-Version 1.5.x onward
The cylinder level display on the VIO HF surgical unit can be set to the
maximum cylinder pressure of the argon gas bottle in use via the set
-
ting "max. APC cyl. pressure" (see Setup level 2).
