Damaged source filament or poor
contact to the filament from the
spring contacts on the outer source.
[Inspect the Tune window Source
page Source Parameters pane
Filament (A) readback].
Remove the inner source and test
the continuity of the filament with a
digital voltmeter (the resistance
must be approximately 0.2 ohm).
Replace the filament if it is
damaged. If the filament is intact,
use tweezers to adjust the spring
contacts on the outer source to
improve contact.
See “To remove the filament
assembly” on page 7-16 and “To fit
