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:
VOLTAGE
TEST POINT RESULT
-5.2
MARKED ON PC-BOARD
4.94 V - 5.46 V
+15
MARKED ON PC-BOARD
14.25 V - 15.75 V
-15
MARKED ON PC - BOARD
14.25 V - 15.75 V
+5
MARKED ON PC - BOARD
4.75 V - 5.25 V
4. Check that the 0602 collector voltage is approximately half the 0601 collector voltage.
