3. EEG/PSG MEASUREMENT
3.14 Operator's Manual WEE-1000
Procedure
This section explains how to attach the disk electrodes. When using collodion disk
electrodes, refer to its operator’s manual.
1. Clean the skin where the electrodes are attached with a cotton swab moistened
with alcohol or SkinPure (skin preparation gel) to remove oil from the skin.
Wipe the skin with a dry cotton swab. When attaching the electrodes for the
EEG measurement, make sure that the skin-electrode contact impedance is 5
kΩ or less.
2. Apply a small amount of EEG paste to a 1 cm diameter circle on the cleaned
skin. Avoid spreading the paste too thin or creating too large a space.
3. Apply a small amount of EEG paste to the disk electrode and press the
electrode down gently on the previously pasted skin spot so that the electrode
leads are toward the ear as shown below.
4. Cover the electrode with a small gauze pad and press the pad around the
electrode.
5. Secure the electrode lead with surgical tape.
6. Hang the electrode leads behind the ear. For an earlobe electrode, the leads
should go up, over and behind the ear.

7. Secure the electrodes with the elastic bandage. Bind the elastic bandage
around the jaw so that the bandage does not come off when the bandage
loosens. This prevents AC interference and the electrodes from detaching
when the patient stands up.
