Appendix C: Diagnostic Routines and Messages
When the CPU detects acquisition timeout, the memory index
LED blinks with 0 and 6, the 371B shuts down with collector supply disabled.
The CPU WAIT ERROR message will be appeared.
Table C–1 shows the Power on System Error Messages displayed on the memory
index display.
Simultaneously pressing the SHIFT and NON STORE buttons enters the
user-initiated diagnostic routine. This routine displays a message that corre-
sponds to the front panel control that you have just operated. Thus, you can
determine if the front panel controls are operating normally. Table C–2 lists the
controls and the corresponding messages. To exit this routine, press both the
SHIFT button and NON STORE button again.
