maxium® smart C Electrosurgery Unit with maxium® smart Beam

HF current must be activatable. The activation lights assigned to the outputs M must be lit in the color
of the activated current – yellow or blue –, and the activation sound must be audible.
–
For combo connections, test the alternative accessories, if any are used.
–
Connect double-pedal foot switch to the large foot switch socket and check whether the channels
assigned on the screen are activated upon actuation of the yellow and the blue pedal; if necessary,
assign foot switch pedals first.
–
Connect single-pedal foot switch to the small foot switch socket and check whether any previously
assigned channel is activated.
–
Connect bipolar test cable successively to the bipolar output ports B.
–
Select the coagulation current with auto-start function and set to minimum power.
–
Check whether a bipolar coagulation current is activated in case of short circuiting of the banana
plugs and deactivated upon opening of the contact.
•
Check the function of the neutral electrode monitoring.
When the NE socket is open, the screen must show the symbol of a red two-piece neutral electrode,
with the pointer of the NE indicator on the left end. Upon activation of a monopolar channel (electrode
handle at M), the intermittent NE alarm is sounded in a clearly audible manner.
–
Insert jumper plug.
The icon of a green single-piece NE must be displayed on the screen (if a non-split NE is allowed,
see section 10.6.4 “Neutral electrode”, page 65); the NE indicator disappears.
–
Insert test connector with 270
Ω
resistor. The pointer of the NE indicator must be in the yellow
field.
•
In the presence of a maxium® smart Beam, first switch off the maxium® smart C, disconnect any argon
gas supply connection from the maxium® smart Beam and then switch on the unit again. The base
program appears on the screen without argon current (select base program if necessary). The indicator
on the maxium® smart Beam must remain dark. On one of the monopolar channels, select an argon-
supported current. The indicator on the maxium® smart Beam must switch to red. The unit may first
have to be set up for operation with the maxium® smart Beam by selecting the function
Argon mode
.
When connecting the gas supply to the gas inlet, the self-test must begin, after whose completion the
indicator will change to green.
•
Check pressure reducer and connecting hose to the unit for leaks.
•
Pressing the key
PURGE
must activate a gas flow without HF current for 3 seconds to displace the air
from the applicator.
•
Function check of activation and activation lamps of the maxium® smart Beam.
On the maxium® smart C, select one argon-supported cutting current and one coagulation current each
and consecutively activate both. Upon activation, the indicator on the maxium® smart Beam must be
lit yellow or blue according to the activated current.
•
Function check of the steadily argon gas flow at the maxium® smart Beam.
Usually a flow measuring unit calibrated for Argon will not be available. As the gas flow, however, is
adjusted by the user not according to the figures measured but according to the visible surgical result,
control of the continuous adjustability of the gas flow is sufficient. Connect argon applicator to the
maxium® smart Beam,
not to the electrosurgery unit!
Via the foot switch, activate an argon-supported
current at the flow rates of 0.3 l/min, 1 l/min, 3 l/min and 10 l/min, in this order. Ascertain by the
sound of the blowing noise that the gas flow increases at each higher stage.
