Move Each Sensor Side To Side Or In A Circle To Establish Scalp Contact; A Properly Applied Net - Geodesic Sensor Net Technical Manual

(Skip Step 6 if you are using an HCGSN without sponge inserts. You perform
this step later, after filling the pedestal with electrolyte formulation, which is
described on page 74.)
Visually verify that each sensor sponge is sitting on the scalp, not on hair. In
7
some cases, such as for subjects with unusually thick hair, a pipette or eye
dropper can help displace hair from under the sponge. If a sponge is unusually
dry, rewet it with a pipette of electrolyte.
Follow a consistent order while working on sensor placement.

Properly positioned sensors (Figure 6-20) should stand perpendicular to the
9
scalp.
