General Cleaning Procedure
Keysight N774xC Series Multiport Power Meter User's Guide
Compressed air
Compressed air can be purchased from any laboratory supplier.
It is essential that your compressed air is free of dust, water and oil. Only
use clean, dry air. If not, this can lead to filmy deposits or scratches on the
surface of your connector. This will reduce the performance of your
transmission system.
When spraying compressed air, hold the can upright. If the can is held at a
slant, propellant could escape and dirty your optical device. First spray
into the air, as the initial stream of compressed air could contain some
condensation or propellant. Such condensation leaves behind a filmy
deposit.
Cleaning Instrument Housings
Use a dry and very soft cotton tissue to clean the instrument housing. Do
not open the instruments as there is a danger of electric shock, or
electrostatic discharge. Opening the instrument can cause damage to
sensitive components, and in addition your warranty will be voided.
Light dirt
If you just want to clean away light dirt, observe the following procedure
for all devices:
•
Use compressed air to blow away large particles.
•
Clean the device with a dry cotton swab.
•
Use compressed air to blow away any remaining filament left by the
swab.
Heavy Dirt
Use this procedure particularly when there is greasy dirt on the connector:
1
Moisten a new cotton-swab with isopropyl alcohol.
2
Clean the connector by rubbing the cotton-swab over the surface
using a small circular movement.
3
Take a new, dry soft-tissue and remove the alcohol, dissolved sediment
and dust, by rubbing gently over the surface using a small circular
movement.
4
Blow away any remaining lint with compressed air.
