Sizing; The Hcgsn Comes In Adult (Left) And Child (Right) Sizes - Geodesic Sensor Net Technical Manual

2: HCGSN
Sensor Array
The geodesic tension structure is die cut from a polyurethane sheet. The resulting
polyurethane web features holes for the sensors, which are "snapped on." An
electrode pellet is first inserted into its corresponding hole; then, a pedestal is
snapped on the other side of the hole, securing the sensor in place in the Net
structure.
Smart Nets
Users of GES 200, 250, or 300 can be aided by "Smart Net" technology. This feature
enables Net Station to sense what type of GSN is connected to the Net Amps (see
"Smart Nets" on page 87). (The GES 120 and 140 do not contain or require "Smart
Net" technology.)

Sizing

The HCGSN is available in various sizes based on head circumference (Figure 2-9).
Instructions for choosing a suitably sized Net are covered in Chapter 6, "Applying the
GSN." A sizing chart is located in Appendix B, "Net Sizing and Sensor Layouts."
