NOTE:
All
voltages
are
measured
with
reference ground (TP7
~
).
1. Measure voltage on
TPl
(approx. 155 V) and TP5 (approx. 133 V) and adjust
A4R604
so
that
the voltage difference between
TPl
and TP5
is
22 V ± 220 mY.
2. Switch
to
30-100
V
AMPLITUDE
Range
and check
that
voltages increase
to
approx. 263 V
(TPll
and
241
V (TP5) .
~
V = 22 V.
3. Check
that
power supply voltages
are
within
limits
as
listed:
