Cleaning Connectors
Clean connector interfaces prolong connector life and produce more accurate
and repeatable measurements.
Cleaning Coax Connectors
1. Use compressed Air or Nitrogen
Use compressed air (or nitrogen) to loosen particles on the connector
mating plane surfaces.
You can use any source of clean, dry, low-pressure compressed air or
nitrogen that has an effective oil-vapor filter and liquid condensation trap
placed just before the outlet hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air
pressure to less than 414 kPa (60 psi) to control the velocity of the air
stream. High-velocity streams of compressed air can cause electrostatic
effects when directed into a connector. These electrostatic effects can
damage the device. For additional information refer to “Electrostatic
Discharge” on page 4-1 earlier in this chapter.
Always use protective eyewear when using compressed air or
nitrogen.
The following cleaning procedure can be used for most coaxial connectors.
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a
tightly closed container. Isopropyl alcohol is extremely flammable. In
case of fire, use alcohol foam, dry chemical, or carbon dioxide; water
may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact
with eyes, skin, and clothing. It causes skin irritation, may cause eye
damage, and is harmful if swallowed or inhaled. It may be harmful if
absorbed through the skin.
Wash thoroughly after handling. In case of spill, soak up with sand
or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all applicable
federal, state, and local environmental regulation.
