Cleaning EUI Connectors
To clean EUI connectors:
1. Remove the EUI from the instrument to expose the connector
baseplate and ferrule.
2. Moisten a 2.5 mm cleaning tip with one drop of isopropyl alcohol
(alcohol may leave traces if used abundantly).
3. Slowly insert the cleaning tip into the EUI adapter until it comes out on
the other side (a slow clockwise rotating movement may help).
4. Gently turn the cleaning tip one full turn, then continue to turn as you
withdraw it.
5. Repeat steps 3 to 4 with a dry cleaning tip.
Note: Make sure you don’t touch the soft end of the cleaning tip.
