Place the ear clip with the black (reference) electrode on to the earlobe of the same side
(ipsilateral) of the location of interest.
Place the earclip with ground snap-on with electrode on to the other earlobe.
Place the red (positive) electrode 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.
Now go to chapter ‘B’ for further instructions.
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.
