Cleaning the Selector
To maintain high performance, the selector must be kept clean. Oil, perspiration,
hair, dust, and dirt will degrade the board insulation, which increases leakage
current and decreases measurement accuracy.
Agilent Technologies recommend the following cleaning procedure:
1. Make sure that voltage or current is not present at any channel.
2. Disconnect all cables from the selector.
3. Using lint-free paper, gently wipe the chassis. For any area that will not come
clean, dip the lint-free paper into alcohol and wipe the area gently.
Servicing the Selector
This section provides information for trained service personnel to repair the selector.
When a replaceable part, which is shown with the Agilent part number in this
section, needs to be replaced, order the parts from the nearest Agilent Technologies
Sales and Service Office.
WARNING High voltages may be present in the selector when voltage or current is applied.
Be careful to avoid electric shock.
Before you repair the selector, make sure that terminals are not connected to any
instrument.
