The following steps should be taken to place these cup electrodes:
• Prepare the area where the electrodes are to be placed. The
skin must be cleaned adequately using abrasive paste. This
allows a good contact impedance (typically less than 10K).
• Fix the electrode to the patient’s skin by filling the cup with
conductive paste and fixing it in place with colodion. A hair
dryer can be used to speed up the drying process. When the
test is over the electrodes are easyly removed with acetone.
• Use a wire adaptor with 2 1.5mm TouchProof connectors to
1mm key connector (ref. 01644) for connecting the couple
of electrodes to the appropriate channel. In order to acquire
the EMG, EOG or EEG signals you must have the ExG module
(optional, ref. 08022). Connect the adapter to any of the three
ExG channels included in the module. Hold the ExG module to
the thoracic effort band.
•
To use a common reference for several EEG channels, each
electrode must be connected to one of the connectors of the
wire adaptors (ref. 01644). Use one or more interconnection
bridges (ref. 02741) to interconnect the remaining pole of all
referenced channels, so that every channel uses the same
reference.
•
Interferences may be reduced by tying together the electrode
wires.
• Place a third electrode on the patient’s forehead and connect it
to the neutral input in the ExG module.
•
The EEG, EOG and EMG signals should not be acquired if the
device is used at patient’s home.
•
According to electrical safety standards and due to the use of
electrodes in contact with the patient, the technician must not
touch any internal part of the device that is accessible without
the use of a tool. For this reason, use the piece 08251 (battery
cover blocking piece) on the battery cover when using the
electrodes and the EXG Module.
In addition to the aforementioned explanations, the following
precautions and considerations should be taken into account while
