Cleaning the FOA Connector Adapter
Make sure that the FOA connector adapter is properly cleaned to assure its
accuracy during calibration.
To clean your FOA connector adapter:
1. Remove the FOA from the instrument.
2. Slowly insert and gently rotate a cleaning tip that has been dipped in
isopropyl alcohol into the FOA.
3. Insert a dry cleaning tip to dry.
4. Blow away any remaining lint with clean compressed air.
5. Use a metal wire (diameter smaller than 150 μm) and carefully insert it
through the sleeve until it comes the other way through the pin-hole
(200 μm).
6. Gently rotate the FOA around the wire to ensure that no particle
remains.
7. Finally, whenever the proper instrumentation is available, a visual
camera with enough magnification might allow to inspect the
cleanliness of the FOA pin-hole.
