Cleaning
When necessary, clean the case, front panel, and rubber boot with a damp cloth. Do not use
abrasives, harsh chemicals, or solvents.
Before Cleaning
• Make sure the power is off to the instrument.
• Make sure the laser source is off when cleaning any optical connectors.
• Make sure AC power is disconnected.
Cleaning Interfaces and Connectors
Interfaces must be kept clean. Isopropyl alcohol may be used to clean the optical output. Always
replace the protective dust caps when the unit is not being used, and keep the protective dust caps
clean. In addition, anges must be cleaned periodically.
Notes:
• The diameter of optic core is 9 um, and the diameter of dust and other particulates ranges
from 1/100 to 1/1000 um. Dust and other particulates can cover part of the optical end and
therefore degrade the performance of the instrument.
• In addition, power density may burn dust into optical ber and induce further damage
(for example, 0 dBm optic power may produce about 16000000 W/m*m power density in
single mode ber). If this happens, the measurement will be inaccurate and damage will be
irreversible.
Tools for Cleaning Interfaces and Connectors
• Optical ber cleaner (for cleaning optical connectors)
• Optical ber cleaning rod (for cleaning optical outputs)
• Optical ber cleaning tissue (for cleaning optical interfaces)
• Isopropyl alcohol
• Paper tissue
• Cleaning brush
• Cleaning swabs
• Condensed air
Procedure for Cleaning Interfaces and Connectors
1. Unscrew the adapter from the bulkhead.
2. Carefully clean the bulkhead and the inside of the adapter.
3. Screw the adapter back onto the bulkhead.
