4. Record the following DC voltage measurements in Tables 8.E to 8.G.
If any voltage measurement is incorrect, refer to the Troubleshooting
manual for guidelines.
•
+5 +/– 0.15VDC measured at TP 51 (+) with respect to TP 52 (–)
on the Main Control Board.
•
+12 +/–0.48VDC measured at TP 55 (+) with respect to TP57 (–)
on the Main Control Board.
•
–12 +/– 0.48VDC measured at TP56 (+) with respect to TP57 (–)
on the Main Control Board.
•
+5 +/– 0.15VDC measured at TP58 (+) with respect to TP53 (–) on
the Main Control Board.
•
+12 +/– 0.48VDC measured at TP54 (+) with respect to TP53 (–)
on the Main Control Board.
•
+24 +/– 6VDC is measured at the Power Stage Interface (PSI) as
outlined in Table 8.E.
