Cleaning this Instrument
This section describes how to clean the instrument.
WARNING
To protect yourself from electrical shock, be sure to unplug the power cable from the
outlet before cleaning the instrument.
Never clean the internal components of the instrument.
Cleaning an LCD
Use one of the following methods to clean the display surface regularly.
•
For normal cleaning, rub the surface gently with a dry, soft cloth.
•
When stains are difficult to remove, gently wipe the surface with cloth damped with a
small amount of ethanol or isopropyl alcohol.
You can clean the standard type LCD (no touch screen function) with a cloth dipped in
water and then wrung tightly.
NOTE
Do not use chemicals other than ethanol and isopropyl alcohol to wet the cleaning cloth.
To clean a touch screen type LCD (Option 016), do not wet the cloth with water.
Maintenance of Test Ports and Other Connectors/Ports
Test ports on the front panel of the E5070B/E5071B are fitted with N Type connectors (f).
Stains or other damage to these connectors would significantly affect the accuracy in
measurements in the RF range. Always pay attention to the following precautions.
•
Always keep the connectors free from stains and dust.
•
Do not touch the contact surface on the connectors.
•
Do not plug damaged or scratched connectors into the test ports.
•
Use compressed air for cleaning connectors. Do not use abrasives under any
circumstance.
The above precautions must also be observed in maintaining connectors and ports other
than these test ports.
Cleaning a Display Other than an LCD
To remove stains on parts other than the LCD, test ports, and other connectors/ports of the
instrument, wipe them gently with a soft cloth that is dry or wetted with a small amount of
water and wrung tightly.
