3.6. ARC control technology
Arc control technology takes into account varying cutting surfaces and
cutting speeds, detects differences in tissue and the resulting changes
in resistance and adjusts the power output to the relevant required
minimum.

3.7. Neutral electrode monitoring
When the neutral electrode is attached, the largest possible neutral
electrode must be attached!
3.7.1. General information
The monitoring of the neutral electrode minimizes the risk of burns at
the site where the neutral electrode is attached.
Two types of neutral electrodes are monitored:
•
Solid neutral electrodes
•
Split neutral electrodes.
The split neutral electrodes are shown on display
20
, and the solid
neutral electrodes are shown on display
19
.
3.7.2. EASY neutral electrode monitoring (EASY monitoring)
Children's electrodes cannot be monitored by the EASY system,
because their resistance is too high due to their small surfaces.
The EASY monitoring system measures changes in resistance between
the patient and the high-frequency surgery device both before and
during HF activation. If required, it requests personnel to intervene via
an optical and acoustic alarm. For this purpose, a split neutral electrode
with corresponding contact surfaces and suitable transition resistances
which is attached to the patient according to the manufacturer's
instructions is required.
For the "TUR" and “Resection” programs and the "Moderate
Coagulation" mode, the minimum surface of the electrode must be at
least 110 cm².
