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, an appropriate Sensor Module must be used for repair.
If error message 241 or 310 is indicated on the power meter, suspect a 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.
Caution Electrostatic discharge will render the power sensor inoperative. Do
not, under any 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 Agilent E-series E9300 power
sensors. If the sensor is defective, replace the entire “module” with the
appropriate “Restored Sensor Module.”
Disassembly Procedure
Disassemble the power sensor by performing the following steps:
Caution Disassemble the power sensor only in a static free workstation.
Electrostatic discharge renders the power sensor inoperative.
