Description
The measurement accuracy could be
decreased because the digital to analog
converter (DAC) remains compensated
with the last valid value of the electronic
temperature.
Permanent storing of modified data
into the electronic Non-Volatile memory
has not been successfully executed.
The device continues to work without
problems but, after the next power cycle
there is the risk to lose the last used
device setting/configuration.
Permanent storing of modified data
into the Sensor Non-Volatile memory has
not been successfully executed.
The device continues to work without
problems but, after the next power cycle
there is the risk to lose the last used
device setting/configuration.
The device power supply has been
detected too close to its higher or lower
acceptable limits.
The electronics temperature is working
beyond its High or Low specification
Possible cause
The circuitry for the sampling
of the electronics temperature has
• The device could have been
powered off immediately
after the modification of the
data that was not fully written
in the NV-memory.
• The NV-memory has reached
its limit of maximum number
of allowed writings
• Generic defect of the memory
component.
• The device could have
been powered off immediately
after the modification of the data
that was not fully written in the
NV-memory.
• The NV memory has
reached its limit of maximum
number of allowed writings
• Generic defect of the
memory component
If the power supply is close to the
highest limit very probably it is due
to a not correct external power
supply while if the power supply is
close to the lowest limit, it could
be due to a defective or not
adequate external power supply or
anomalous voltage drop on the
loop i.e. too long or not correct
This condition could be due to the
circuitry for the sampling of the

to the transmitter installation e.g.

transmitter housing, or critical
ambiental conditions.

Check the voltage at the

If necessary, use a HART
