Customer Service
To request assistance with any question or problem, call Doble Engineering Customer Service at

Service for help, please take the following preliminary steps:
• Review the pertinent portions of this user guide.
• Check all cable connections.
• Work through the diagnostic flow charts shown in Chapter 5 to identify and isolate
problems in F6300 operations.
• Perform the Component Checkout Procedures in Chapter 5 to verify component
operations.
• If the instrument fails during a relay test and another instrument is available, try the test
using the second instrument.
• If the instrument fails during a relay test, compare the requirements in the test plan to
your test setup and source configuration.
If possible, have the instrument set up near a telephone to facilitate telephone assistance. Please
have the following available when calling Customer Service:
• The instrument serial number, which is found on the bottom outer case of the F6300.
• The hardware configuration and software revision, which are displayed on the
instrument front panel during the bootup sequence.
• A precise description of the problem. Include any error messages that have appeared,
and the sequence of events leading to the messages.
• The solutions that have been tried.
• Electronics tool kit and digital multimeter, in case Customer Service suggests that a
board or subassembly be removed.
Write down the name of the Customer Service representative, and ask to speak to the same
person during subsequent calls. Write down any instructions the representative gives during a
service call.
Returning the F6300
If troubleshooting checks and the replacement of defective parts in the field fails to correct a
problem with the instrument, the F6300 may need to be returned to Doble for servicing. Contact
Doble Engineering Customer Service at 617-926-4900 before shipping the instrument.
To prepare the F6300 for shipping, disconnect all external cables and attach the cover that
protects the front panel of the instrument. Use the original packing materials if they are available.
If the original packing materials are not available, pack the instrument for shipment as for any
fragile electronic equipment.
Triple-wall shipping containers can be ordered from Customer Service for a nominal charge
(Doble Part # 903-0045). Alternately, the instrument may be packed using either of the following
methods:
• Double-wall cardboard box with a minimum of 2-inch thick poly foam padding all
around.
• Wooden crate with a minimum of 2-inch thick poly foam padding all around.
