Appendix A
Error Codes and Message
Introduction
Note
For the sake of completeness, this appendix collects together the error
codes which might be generated either on the instrument front panel, or via
the IEEE 488 system bus.
Error Detection
Errors are classified by the method with which they are handled:
• Recoverable errors are reported to the user and the Multimeter continues operation.
• Fatal errors are reported to the user but the Multimeter cannot recover and halts
operation. Restarting the Multimeter from power on may clear the error, but
generally such messages are caused by hardware or software faults, which require
repair by a service center.
Error Messages
Fatal Errors
For all fatal errors, the error condition is reported only via the front panel.
The processor stops after displaying the message. A user must respond by retrying
operation from power on, and initiate repair if the fault persists. The following is a list of
error numbers displayed, with their associated fault descriptions:
9000- System Kernel Fault
001- Run Time System Error
9002- Unexpected Exception
9003- PROM Sumcheck Failure
9004- RAM Check Failure
9005- Serial Interface Fault
9006- Option Test Failure
9007- Unknown Engine Instruction
9099- Undefined Fatal Error
A-1
