The error history stored inside the NZ2AW1GNAL can be read. The error that occurred before the power turned off can also
be checked.
• The error history records up to 16 errors in the order of most recent. If 17 or more errors occur, the oldest
errors are deleted in order.
• If the same error occurs consecutively, only the first instance of the error is stored in the error history.
• Error history is stored in the non-volatile memory of the NZ2AW1GNAL and does not disappear even after
the power supply is turned off. However, if the upper limit on the number of times that the non-volatile
memory can be written is reached, the error history cannot be stored in the non-volatile memory.
• The date and time of occurrence in the error history is recorded after the time is delivered from the master
station. If an error occurs before the time is delivered from the master station, the date and time of
occurrence will not be recorded.
