amplitude artifact) Inadequate skin
preparation • Prepare skin as described on page 4-8 and
apply new electrodes.
Poor electrode-skin
contact • Check electrodes for proper adhesion.

(high frequency/low
amplitude) Inadequate skin
preparation • Prepare skin as described on page 4-9 and
apply new electrodes.
