8.1.4.- Information to be taken into account in the recording of the periodic
values.
There are a series of points to precisely define which information must be
used to calculate the recordings.
Therefore the following may be defined:
• Description of the Measurement point: This is only an identification field
used by the user.
• Comment: This is only an identification field used by the user.
• Recording Period: All electrical parameters will be recorded at the end of the
pre-set time (those parameters selected only). The average values obtained
during that period of time will be recorded. As default the recording period is
set at 10 Minutes. This value may range from 1 minute to 2 hours.
• Integrating blocks of 10 cycles with events (all except voltage): (Affects
the .STD file only). While the average voltage, flicker, harmonics are being
calculated, it is possible that an event occurs (overvoltage, dip, etc.). The QNA
allows (or does not allow) the 10 cycle block where such an event occurred to
be added to the integration. When this option is deactivated ("No"), the 10
cycle block will only be added to the average voltage.
• Integrating blocks of 10 cycles with events (voltage): (Affects the STD file
only). While the average voltage is being calculated, it is possible that an
event occurs (overvoltage, dip, etc.). The QNA allows (or does not allow) the
10 cycle block (this may be one or more depending on the length of the event)
where such an event occurred to be added to the integration. When this option
is deactivated ("No"), the 10 cycle block will only be removed and therefore not
added to the integration of this recording period. This option does not affect
the other parameters.
• Recording period: (Affects the STD file only). This is the period when the
averaged values are stored.
• Type of date: (Affects the STD file only). The date/time when the recorded
data in a recording is to be saved may be selected (Affects the STD file only).
This may be at the start or end of the recording.
• Battery disconnection time: The QNA may set the time for self
disconnecting the equipment when there is no mains supply. This means that
the battery is not completely run down when there are problems with electricity
supply. A typical value is about 15-30 mins.
8.2.-
Variables to Record.
The QNA-412 stores all quality parameter recordings in its internal memory.
Data is stored in three files:
