Cap Set-Up

1. Cap Sizes

• Use measuring tape to measure head circumference in centimeters (cm). See NIRS cap user guide for detailed information on how to measure properly or view the video tutorial. 
• NIRS cap sizes come in whole, even numbers from 52-60.
• If head size is not an exact, even number then round up/down accordingly:

53 or lower = 52 cap

53.1 - 55 = 54 cap

55.1 - 57 = 56 cap

57.1 - 59 = 58 cap

59.1 or higher = 60 cap

2. Add Grommets/Labels

If you need to set-up your cap's montage, use the cap accessory kit to add the grommets and labels. Use grommet rings to secure grommet base to cap (do NOT use ring for sources that will be connected using a short channel bundle) 

 

 

 

 

 

 

3. Add short channel bundles

If using short channels, flip the cap inside out and connect the short channel sources. Use wire organizer clips to hold down short channel wires so they don't block grommets.

 

 

 

 

4. Add source/detector optode cables

You can connect cables in any order you want, but starting from back of head can make organizing cables easier. If using short channels, don't forget to connect appropriate detector optode to short channel bundle using the canisters 

5. Organize cables

After all cables are connected, try to organize them to improve slack/relieve heaviness at the back of the head. You can use trees, straps, fiber arm, etc 

6. Connect cables to device

Make sure that you are connecting the cable to the correct plug on the amplifier. Note whether cable is source/detector and number (1-8 or 9-16)
