Apply some Electro gel to the electrodes by using a cotton swab or a syringe with blunt
needle.
Place the ear clips with the black (reference) electrodes on to the left and right earlobe.
Place the ground electrode preferably near the other reference electrodes on the scalp. Use
the Minicap or Microcap to fix the electrodes.
Place the red (positive) electrodes on to the skin at the location of interest. Use the Minicap
or Microcap to fix the electrode. The minicap also allows for placing the electrodes on the
mastoids instead of the ear. In that case the earclips aren’t necessary.
Due to the fluid nature of electro gel, rubbing the skin with an abrasive gel is usually not necessary.
When using electrode paste (e.g. Ten20), rub the skin with a cotton swab and Nuprep at all
electrode positions. The location of the ground electrode is preferably near other electrodes on the
scalp. Remove residual gel with a tissue. As an alternative to using Nuprep, alcohol pads are
sometimes used.
