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.
