6.2.3.- Incidents file (EVE)
All incidents referred to the
QNA-303
itself are automatically saved into this file,
with the indication of both the occurrence moment and type. Following incidents can
be detected and recorded by the
QNA-303
:
Battery ON:
Indication of the moment when the
QNA-303
started to be supplied by
its on-board battery.
Battery OFF:
Indication of the moment when the
QNA-303
stopped its operation.
This moment depends on the value set by the user as the period of time of operation
after a voltage supply loss.
Auxiliary power supply ON:
Indication of the moment when the
QNA-303
is
connected to the external power supply.
Auxiliary power supply OFF:
Indication of the moment when the external power
supply
of the
QNA-303
is interrupted. The analyzer is supplied from this moment by
the on-board battery.
Setup modification:
Record of the moment when any modification of the instrument
setup is realized.
Memory formatting:
Indication of the moment when the user has decided the
QNA-
303
internal memory to be formatted.
Forced memory formatting:
The
QNA-303
internal memory will be automatically
formatted if any error in this internal memory is detected.
Delete a file
: Indication of the moment when the user has deleted any file from the
QNA-303
internal memory. If the first data shown by the .EVE file is the indication
that a file has been delete, then this means that the deleted file was the events file.
Time change:
Indication of any change of the date or time of the analyzer’s on-board
clock. The record of this event type is quite important, since when illogical intervals of
time between two successive readouts are observed in the graphical representation
of any parameter, this might be due to a change of the time of the on-board clock.
