Neutral electrode operation
7.2 Split type and non-split type neutral electrodes and CQM
Contact quality monitoring (CQM) for split type neutral electrodes
If a split type neutral electrode is connected to the electrosurgical generator, it is possible
to detect unintended detachment of the neutral electrode from the patient. If the contact
between the neutral electrode and the patient’s skin is insufficient, the split type CQM
indicator shines red. Furthermore, an alarm tone sounds and the following error message is
displayed on the touch screen:
Figure 7.1 Error message E0202 “Insufficient neutral electrode contact”
In this case, the activation of the electrosurgical generator is stopped automatically. The
neutral electrode must be reattached or a new one must be used. The split type CQM
indicator will only shine green while the contact between the neutral electrode and the skin
of the patient is within an acceptable resistance range, see section “Specifications for the
CELON ELITE ESG-200” on page 90.
No contact quality monitoring for non-split type neutral electrodes
If a non-split type neutral electrode is connected to the electrosurgical generator, it is
impossible to detect any detachment of the neutral electrode from the patient. When
connecting a non-split type neutral electrode, the following message box is displayed on the
touch screen:
Figure 7.2 Message box “Neutral electrode”
To avoid unintended use of a non-split type neutral electrode the displayed message must
be confirmed by the user.
