Cleaning Instrument Housings
Use a dry and very soft cotton tissue to clean the instrument housing and the
keypad. 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.
Which Cleaning Procedure
should I use ?
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 If the above procedure is not enough to clean your instrument, follow one of the
procedures below. Please consult “Cleaning Instructions for this Instrument” on
page 266 for the procedure relevant for this instrument.
If you are unsure of how sensitive your device is to cleaning, please contact the
manufacturer or your sales distributor
How to clean connectors
Cleaning connectors is difficult as the core diameter of a single-mode fiber is only
about 9 µm. This generally means you cannot see streaks or scratches on the
surface. To be certain of the condition of the surface of your connector and to
check it after cleaning, you need a microscope.
In the case of scratches, or of dust that has been burnt onto the surface of the
connector, you may have no option but to polish the connector. This depends on
the degree of dirtiness, or the depth of the scratches. This is a difficult procedure
