7.3 Error configuration
The SA11 contains error diagnostics, which is a summary of all related measurement
warnings, diagnostics, sensor statuses and other kind of failures. Part of the configuration
will be pre-defined by the sensor configuration as stored in the ID-chip.
Errors can be defined in different levels: critical and fail. An error will always result in non-
calculated output data or a pre-defined value. These errors and related limits are not user
configurable. Beside this there are configurable measurement warnings. A warning is only a
flag and has no consequence for calculated output data.
At last there are sensor- and device statuses which reflect a certain state of performance
and/or operations. A sensor failure can result in a critical device error.
The SA11 show the four (4) categories:
• Critical device errors
• Sensor failures and sensor statuses
• Measurement warnings on calculated outputs
• Device status

+260°C / +500°F or +250ºC / +482ºF)
Temp. too low (note 4)
Min. limit (set by HOST for
-40°C / -40°F or -20ºC / -4ºF)
Input resistance too high (note 5)
Max. limit (100MΩ)
Input resistance too low (note 5)

(note 6)
Not a number
Note 1:
NVM= Non Volatile Memory which is a type of memory that can retrieve stored information
from SA11 even after a power down.
Note 2:
not a number means that there is no result of calculated output data.
Note 3:
CRC= Cyclic Redundancy Check, which is data verification.
Note 4:
Limit set depends on capabilities of the HOST system.
Note 5:
Input resistance is the uncompensated ‘raw’ value.
Note 6:
The SA11 has an internal temperature element which measure temperature of electronics. If
the design temperature is outside the limits of -40°C up to +130°C an error will be flagged.

Note:
In case of sensor safely remove there will be no up date of data to sensor ID until reset.
