Troubleshooting; Repair Of Defective Sensor; Cleaning - Keysight Technologies E4412A Operating And Service Manual

Troubleshooting

Troubleshooting information is intended to first isolate the power sensor,
the cable, or the power meter as the defective component. When the power
sensor is isolated, a "Restored Sensor Module" must be used for repair.
See
If error message 241 or 310 is indicated on the power meter, suspect failed
power sensor. If no error message is displayed, but a problem occurs when
making a measurement, try replacing the cable from the power meter to
the power sensor. If the problem still exists, try using a different power
sensor to determine if the problem is in the power meter or in the power
sensor.
Electrostatic discharge will render the power sensor inoperative. Do not, under any
C A U T I O N
circumstances, open the power sensor unless you and the power sensor are in a static
free environment.

Repair of Defective Sensor

There are no serviceable parts inside the E44XX- Series sensors. If the
sensor is defective, replace the entire "module" with the appropriate
"Restored sensor Module." See

Cleaning

Cleaning Solutions
Keeping in mind its flammable nature; a solution of pure isopropyl or
ethyl alcohol can be used to clean the connector.
Connector Cleaning
The RF connector beads deteriorate when contacted by hydrocarbon compounds such
C A U T I O N
as acetone, trichloroethylene, carbon tetrachloride, and benzene.
