alcohol directly to the parts).
4. Gently wipe connecting surfaces with the end of the cleaning swab.
5. Blow dry with compressed air.
6. Inspect and repeat cleaning procedure if necessary.
Visual Inspection
Visual inspection and, if necessary, cleaning should be done every time a connection is made.
Metal particles from connector threads may fall into the connector when it is disconnected. One
connection made with a dirty or damaged connector can damage both connectors beyond repair.
Magnification is helpful when inspecting connectors, but it is not required and may be misleading.
Defects and damage that cannot be seen without magnification generally have no effect on
electrical or mechanical performance. Magnification is of great use in analyzing the nature and
cause of damage and in cleaning connectors, but it is not required for inspection.
Obvious defects or damage
Examine the connectors first for obvious defects or damage:
1. Plating
— Bare metal showing
2. Burrs or blisters
3. Deformed threads
4. Center conductors
— Bent
— Broken
— Misaligned
— Concentricity
5. Connector nuts should move smoothly and be free of:
— Burrs
— Loose metal particles

When using isopropyl alcohol to clean connectors do not allow the liquid
to flow down Keysight U9361 RCal Receiver Calibrator – Startup and
Demonstration Guide page 6 | 28 inside the connector. This may cause
measurement errors due to residue inside the connector. If possible, keep
the connector downward facing.
