8.1.4.- Data to take into account for the periodical data recording process
Some points to allow the user to precisely define the information to be
used for the recording calculation procedure .
Therefore, the user can define:
•
Description of the measurement site: An identifying field to be filled in by
the user.
•
Remark: An information field to be filled by the user.
•
Recording period: (affecting the .STD file only). The recording period of the
integrated values. The recording period is, by default, set at 10 minutes, but
this value is user-settable from 1 minute to 2 hours.
•
Integration of 10-cycle blocks with events (all except for voltage):
(affecting the .STD file only). An event might occur (voltage swell, dip, …)
while the analyzer is calculating the voltage, flicker, harmonic averages. The
QNA-P/PV allows the 10-cycle block where the event occurred to be added to
the integration. If this option is disabled ( “No”), then the 10-cycle block would
be only added to the voltage average.
•
Integration of 10-cycle blocks with events (voltage): (affecting the .STD file
only). An event (voltage swell, dip, …) may occur while the analyzer is
calculating the average voltage. The
QNA-P/PV allows the 10-cycle block
where the event occurred to be added to the integration (this may be for one
or more event, depending on the duration of the event). If this option is
disabled ( “No”), then the 10-cycle block would be ignored, and, therefore, it
would not be added to the integration for this periodical recording. This option
does not affect the other parameters.
•
Date type: (affecting the .STD file only). Permits the user to select date/time to
be saved together with each recording. This date can be the initial or final
recording.
•
Battery auto-power off timer: The user can set the time for the QNA-P/PV
battery auto-power to switch off in the event of supply voltage loss, in order to
save the battery and to ensure the detection of possible intermittent voltage
interruptions. The usual time is about 15-30 min.
