Protected Memory Corruption
Protected Memory Corruption
The
i
Matic tests the status of the protected memory each time power is applied to the
unit. If the “memory status word” indicates that the memory is corrupted, the unit
automatically re-initializes the detector parameters, system unique identifiers and the
real-time clock to default values. It then automatically initiates a system master clear.

Corruption of the protected memory is typically caused by a dead backup-battery
(different from the primary power-batteries) or when a replacement controller board is
installed in the instrument and the firmware is first loaded into the controller.
The presence of the “Protected Memory Corrupted” message on power-up of the
i
Matic indicates abnormal operation that should immediately be investigated.
Note: The
i
Matic will no longer be calibrated after the “Protected Memory
Corrupted” message and resulting system “Master Clear”.
