3.6. ARC Control technology
The "ARC Control" regulator takes varying cutting surfaces and cutting
speeds into account, detects differences in tissue and the resulting
changes in resistance, and adjusts the output power to the minimum
level necessary under actual conditions.

3.7. Neutral electrode monitoring
Always use the largest possible electrode when attaching a neutral
electrode.
3.7.1. General information
BOWA recommends using split neutral electrodes, since only this type of
electrode allows the HF device to detect detachment of the neutral
electrode if this occurs.
Monitoring of the neutral electrode minimizes the risk of burns at the site
where the neutral electrode is attached.
Two types of neutral electrodes can be monitored:

One-piece neutral electrodes

Split neutral electrodes.
The split neutral electrodes are shown on display 20 , and the one-piece
neutral electrodes are shown on display 19, see chapter Error Display in
EASY monitoring, page 55.
