A system error occurs when a fatal fault is detected during operation. All operation
of the instrument is halted and the CPU operation status data at the system error
appear on the left top of the screen. The system error is mostly stored in the error
history table. In a few seconds after the status data is displayed, the instrument
restarts. If the instrument repeats the restart, the MAIN board will be faulty.
