during operation, the sensor probes are checked against failure by checking the valid
dynamic measurement ranges. All EEPROM updates, initiated by the sensor itself, as
well as by external connections, are checked by subsequent memory read back and
data comparisons. These different system checks return error bytes to the system
RAM. The error codes are available by connecting a PC with a special RS232 cable
connected to the UART port slide connector. The error codes are shown in the
software UIP (version 4.3 or later). Warm up and Out of Range are the only bits that
are reset automatically after return to normal state. All other error bits have to be
reset manually after return to normal by power off/on.
The yellow LED flashes if an error has been detected. If a fatal error has been
detected the yellow LED is lit.
