is O.K. A normal amount of pressure must suffice to perform the click and carry out the function
(red frame disappears).
9. Checking the current activation, the activation indicators and the acoustic activation signal for
proper functioning: Deactivate the NE alarm with the shorting plug, then connect the electrode
handle successively to M1 and M2 and operate the two finger switches. This must activate the
HF current. At the same time, the activation LED belonging to the respective output (M1 or M2)
must come on in the color of the activated operating mode (i.e. yellow or blue), and the activa-
tion signal must be heard in addition. In the case of multifunction connectors, alternative ac-
cessories must be checked as well, inasmuch as they are used as well. Connect the dual-pedal
footswitch to the large footswitch socket, then check that the channels assigned to it are cor-
rectly activated when operating the yellow or blue pedal, respectively (if necessary, assign the
footswitch pedals first). Thereafter, connect the single-pedal footswitch to the small footswitch
socket and verify that operating the footswitch activates the channel assigned (again, assign
footswitch first if necessary). Connect the bipolar test cable to the bipolar outputs B1 and B2
(one after the other), then select a coagulation current with auto-start function and set it to
minimum power. Now check that bipolar coagulation current is activated when shorting the ba-
nana plugs and deactivated when opening the contact. Subsequently, connect the test adapter
to output B2 and verify that the finger switches can be activated on the handle.
10. Checking the neutral electrode monitoring system for proper functioning: When the NE con-
necting socket is open, the split neutral electrode symbol must be displayed in red and the slide
of the graphical NE indicator (which must first be enabled via the menu if not displayed yet)
must be at the left end of the bar. Upon activating a monopolar channel (via electrode handle
connected to M1 or M2), the intermittent NE alarm signal must now be clearly heard. Insert the
shorting plug. The non-split (single-surfaced) NE symbol must now be displayed in green and
the slide symbol must disappear. Insert the test plug with a resistance of 270
Ω
. The slide of
the bar-type NE indicator must now be in the range of the yellow field.
11. If a maxium Beamer is connected, switch off the maxium HF unit, then disconnect the argon
gas supply from the maxium Beamer (if applicable) and turn on the maxium again. The stan-
dard program (without argon current) must now be displayed and the Beamer indicator must
remain dark. Select an argon-supported current on one of the monopolar channels. The
Beamer indicator must now turn red. If necessary, the maxium unit must first be configured for
maxium Beamer operation via the “Argon” menu item. Reconnect the gas supply line to the gas
outlet. The self-test must now be started. Upon its completion, the indicator must turn green.
12. Check the pressure reducer and connecting hose for tightness.
13. Operate the PURGE button. This must activate a pure gas flow (without HF current) for 3 sec-
onds. This function is used to clear the air from the applicator prior to use.
14. Checking the activation function and the activation indicators on Beamer: Select an argon-
supported cutting current and an argon-supported coagulation current on the maxium, then ac-
tivate them one after the other. Upon activation, the Beamer indicator must light up either yel-
low or blue, depending on the type of current activated.
15. Checking the Beamer’s argon gas flow for continuous increase: Usually, an argon-calibrated
flow meter will not be available. Anyway, as the user will control the gas flow according to the
observed surgical result rather than by (abstract) measured values, it is enough simply to
check the continuous adjustability of the gas flow. Connect an argon applicator to the Beamer,
