Calling Up the Error History
The ERROR HISTORY screen shows the error history of the instrument. The error
code, board name, time, and date the error occurred are listed on this screen. For an
explanation of error codes, see the “Error Codes” section. The error history data is
deleted whenever system initialization is performed.
1. From the DIAGNOSTIC CHECK screen, touch the “HISTORY” key. The
HISTORY screen appears. Then, touch the “ERROR HISTORY” key to display
the error history.
2. Touch the “PRINT” key to print the screen with the recorder.
3. To return to the MANUAL CHECK MENU screen, touch the “RETURN” key.
When a fault is detected during operation or during the power on self check, the
error is stored in the error history table. The error codes stored in the error history
are only deleted when system initialization is performed. If the memory space for
the error history is filled up, however, the oldest error code is deleted when a new
error code is added.
The message and description of each error code are described in the following
table:
Error Code Message Description
0110 WATCH DOG Interrupt from the watch dog timer
0210 BUS Bus error occurred when an empty address was
selected
0220 ADDRESS Address error when a word accessed the odd
address
