Section 12: Maintenance

Front-panel display

Do not use sharp metal objects, such as tweezers or screwdrivers, or pointed objects, such as pens

or pencils, to touch the touchscreen. It is strongly recommended that you use only fingers to operate

the instrument. Use of clean-room gloves to operate the touchscreen is supported.

If you need to clean the front-panel LCD touchscreen display, use a soft dry cloth. If necessary, use a

cloth dampened with an ammonia-free glass cleaner. Do not spray cleaning fluids onto the display.

You can use the Front Panel Control option to adjust the brightness of the screen and to enable or

disable the touch screen.

The Front Panel Control option is in the Windows system tray at the bottom right of the screen.

Your 4200A-SCS comes equipped with an internal axial fan for active cooling of the instrument

cards. Your instrument must be properly cooled to maintain optimum operating specifications.

There are three air inlets on your instrument: One on each side and one on the bottom.

Every six months or when a screen appears to be clogged, use a vacuum cleaner with a soft brush

attachment to carefully remove the accumulated particulates. The screens must remain unrestricted

to provide sufficient cooling airflow.

Never use compressed air to blow debris from the screens. Doing so can force particulates through

the screen and into the instrument.
