Appendix A: Error Listings - AEMC 6470 User Manual

There are some tests made when the instrument is switched on. Generally if an
error occurs which can be removed by overwriting default values it is done auto-
matically and an error code is given to the user. This message lasts until the rotary
switch is moved.
If an error occurs that means service support is necessary, the error stays on the
display and the instrument is out of order.
Three types of errors are managed on the instrument:
• Fatal error: Error state until power off; service is needed at once if the failure
does not disappear.
• Recoverable error: Error state until rotary switch change; instrument can be
used, but unit should be serviced if the failure occurs repeatedly.
• Harmless error: Error message displayed for 1 sec; only for information, but
unit should be serviced if the failure occurs repeatedly.
