5.4. SUGGESTIONS FOR
TROUBLESHOOTING
In sit uations where the 480 is suspected of
malfunction, it is essential to verify such malfunction
in terms of simple pulse generator impulses at the
out put. In consideration of this, the 480 must be
disconnected from its position in any system, and
routine diagnostic analysis performed on the Pulser
with a vacuum tube voltmeter and oscilloscope. It is
imperative t hat testing not be performed with any
amplifier system unt il the Pulser performs
satisfactorily by itself. The testing instructions of
Section 6.1 of this manual and the circuit description
in Section 5 are int ended to provide assistance in
locating the region of trouble and repairing the
malfunction. The guide plate and shield cover can
be completely removed from the module to enable
oscilloscope and voltmeter observations with a
minimum chance of accidentally short c ircuiting
portions of the etched board.
The 480 may be returned to ORTEC for repair
service at nominal cost. Our standard procedure
requires that each repaired instrument receive the
same extensive quality control tests that a new
instrument receives. Contact our Customer Service
Department, (865) 483-2231,
for
s hipping
instructions before returning an instrument.
