Soaking the Net in Electrolyte
During this stage, do not soak the Net longer than necessary and do protect the
Hypertronics connector from contact with liquids. The following instructions apply to
the GSN 200 and the HCGSN
with sponge inserts; for the HCGSN without sponge
inserts, follow only Steps 3–5 (remembering to protect the connector from liquids),
and then proceed to the next section, “Proper Position of Hands” on page 64.
1 Dip the sensor end of the Net into the “electrolyte” bucket (Figure 6-5); be
careful to prevent the Hypertronics connector from coming in contact with the
electrolyte.
2 Soak the sensors of the Net in electrolyte for at least 5 minutes to ensure
adequate wetting of the sponges. Gentle agitation of the Net facilitates the
process.
Caution!:
Throughout the application process, protect the connector end of the Net
from contact with liquids.
3 Give the subject a towel to catch electrolyte drips.
4 For subjects with long hair, ask them to brush their hair back, so that it falls
toward the back of the head, away from the face.
5 Drape a towel over the subject’s shoulders.
