8.1 Storing/Recalling Measured Data
Explanation
8-2
Storing Measured Data (Storing into Internal Memory)
The number of blocks which can be stored into the internal memory is as follows.
During Normal Measurement
600 blocks
Items which can be stored
All the data that are obtained while the display is updated once are stored as one
block of data. The data number increases by the number of used input elements
and therefore the number of blocks that can be stored depends on the model as
described above.
• When storing normal measured data (harmonic analysis function is turned OFF)
Each measured/integrated data of normal measurement will be stored.
However, only either the voltage frequency or current frequency will be stored
* When either the V Hz or A Hz display function is lit, the frequency of that
function will be stored. When neither is lit, the frequency of the latest lit
display function will be stored. Regarding the element, the frequency of the
latest set element will be stored.
• When storing harmonic analysis data (harmonic analysis function is turned ON)
Normal measurement data are not stored. All analyzed data are stored.
Aborting Storage
• When all the above described blocks are full;
• When during the storage process "oFF" is selected at the store ON/OFF setting.
Setting the Storage Interval
Sets the time during which storage will be carried out.
• When storing normal measured data (harmonic analysis function is turned OFF)
• Setting range: 00.00.00 (0 hrs, 0 min, 0 sec) to 99.59.59 (99 hrs, 59 min, 59 sec)
• Initial value: 00.00.00
When the setting is 00.00.00, the interval will become 250 ms.
• When storing harmonic analysis data (harmonic analysis function is turned ON)
• Setting range: 00.00.00 (0 hrs, 0 min, 0 sec) to 99.59.59 (99 hrs, 59 min, 59 sec)
• Initial value: 00.00.00
When the setting ranges from 00.00.00 to 00.00.03, the interval will become 3s;
from 00.00.04 to 00.00.06, the interval will become 6 s; from 00.00.07 to
00.00.09, the interval will become 9 s; in other cases, the set interval will be
valid.
Note
The displayed values of V (voltage), A (current), W (active power), VA (apparent power), var
(reactive power), Vpk (voltage peak), and Apk (current peak), while the MAX hold function
(see section 4.8) is enabled, will be the maximum values (MAX) that are held. The values for
D/A output, output to external plotter and printer, and communication output are also set to
the maximum values (MAX) that are held. The measured data that are stored are values that
are measured at every display update rate, irrespective of the MAX hold function.
During Harmonic Analysis
30 blocks
