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 via the variable
pressure regulator.
• 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.
Test procedure
1st test step 1. Reduce the input pressure on the test specimen slowly (from 5 bar)
using the variable pressure regulator. When doing so, check the actual
pressure on the pressure gauge.
2. Press the Purge button. Gas flow is generated and the actual pressure
is reduced.
3. When the actual pressure drops to <2.5 bar, the test specimen must
display the underpressure warning "A-10".
2nd test step 1. Increase the input pressure on the test specimen slowly (from 5 bar)
using the variable pressure regulator. When doing so, check the actual
pressure on the pressure gauge.
2. When the input pressure rises to >7.5 bar, the test specimen must
display the overpressure warning "A-11".
IMPORTANT! For this test only Erbe pressure reducers may be used. For article num-
bers see chapter "Testing and measuring equipment".
