Storing Measured Data (Storing into Internal Memory)
The number of blocks which can be stored into the internal memory is as follows.

In case of normal measurement
In case of harmonic analysis

Items which can be stored
One block consists of all data which are obtained when the display is updated once. 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
*1
.
*1 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 measured data will not be stored. All analysis data of the elements which are being
used for analysis, will be 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 (0hrs, 0min, 0sec) to 99.59.59 (99hrs, 59min, 59sec)
• Initial value
: 00.00.00
When the setting is 00.00.00, the interval will become 250ms.
• when storing harmonic analysis data (harmonic analysis function is turned ON)
• Setting range : 00.00.00 (0hrs, 0min, 0sec) to 99.59.59 (99hrs, 59min, 59sec)
• 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 6s; from 00.00.07 to 00.00.09, the interval will
become 9s; in other cases, the set interval will be valid.
Storage ON/OFF
After having set the storage interval, select the store menu once again. The initial value is oFF.
• on : Storing will start by pressing the ENTER key after selecting “on”; the STORE
indicator will light while storage is in progress.
• oFF : Storing will stop by pressing the ENTER key after selecting “oFF”; the STORE
indicator will extinguish.
Note
• After storing has been stopped and storing is restarted, the existing data in the memory will be
overwritten. Previous data will therefore be lost.
• Stored data will be kept even after the power has been turned OFF because of the internal lithium
battery.
• When integrated values are not present, the dot display will be stored as data, whereas 000.00 will be
stored as integration preset time.
• When the fundamental frequency is high and up to 50 windows of harmonic analysis data are not
present, the dot display will be stored as data.
• While storage is in progress, several settings cannot be changed, such as switching the harmonic analysis
function ON/OFF, changing the related input element, the PLL source, the harmonic distortion factor
computation method, nor can scaling, averaging and filter settings be changed, nor integration mode,
integration time and storage interval.
• If you press the HOLD key while storing data, the measurement operation and the counting operation of
the store interval are suspended. The storage operation itself is also suspended. However, if integration
is in progress, measurement and integration continues internally.
