Cleaning EUI Connectors

Regular cleaning of EUI connectors will help maintain optimum performance. There
is no need to disassemble the unit.

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.
