Attach the neutral electrode over the entire contact surface evenly. Secure
reusable neutral electrodes with rubber bands or elastic straps so that they do not
loosen when the patient moves. Ensure that the patient’s circulation is not impaired
(risk of necrosis).
Never use wet clothes or conductive pastes.
Ensure that no liquids (e.g. cleaning fluids, disinfectants, blood or urine) penetrate
between the patient and the neutral electrode.
Do not place the neutral electrode under the patient’s buttocks or back.
Ensure that there are no ECG electrodes in the current path of the HF device.
Check the neutral electrode before and after use for damage and to ensure that
they are working properly.
Replace defective accessories immediately
Example application using a disposable electrode
Remove the protective film and attach the self-adhesive disposable electrode to
the patient. Ensure that the long edge of the disposable electrode faces the
operation site and the electrode is fully in contact with the skin. This avoids
excessive current concentration on the short edge.
Using both hands, press the self-adhesive disposable electrode firmly against the
patient’s skin.
Clamp the electrode tab to the neutral electrode cable.
After the operation, remove the disposable electrode carefully to avoid skin
damage.
With a one-piece neutral electrode
Check the one-piece neutral electrode during surgery.
Ensure that the one-piece electrode is not blocked at the device.
With a split neutral electrode
Apply the split neutral electrode correctly and without any additional objects, as
otherwise the HF device may detect a path between the two sections due to other
objects.
See that the current flows equally to both parts of the split neutral electrode.
See Section Fault indications for EASY monitoring, page 84 regarding
monitoring of the neutral electrode.
