5.2 Data saving procedure (6-4)
The instantaneous value (on W range) can be saved only by a manual operation.
Opening a file
Pressing the key on
W range during a measurement displays
File number screen and file is opened. (First data is recorded at this stage.)
W range File number screen W range
Pressing the key again records next (second) data stream.
Closing a file
Set the Function switch to any position other than W and OFF .
Completing Data saving Procedure
According to above procedure, data can be saved to one file whenever the key
is pressed.
* When data is saved to the internal memory, the mark is displayed instead of the mark.
* File shall be closed first. Data will not be saved when a file is not closed.
* File has to be closed ! Data will not be saved unless a file is closed.

* In case the data to be saved to the internal memory, the mark is displayed instead of
the mark.
* Ensure that the file is closed. Data will not be saved unless a file is closed.
After a measurement, demand value is kept indicated on the display screen.
Demand value is reset (8-5) by pressing the key for at least 2 sec. and select
“dEL”, or at “Setting 18”.
File number screen is displayed for about 2sec. (open a file)
* Start measurement manually.
* When automatic measurement is set, the instrument goes into

7.2 Display screen / Data capturing
● Display screen modes
Three display screens are common to each wiring configuration, and can be activated
as follows.
Upper : Target value Upper : Remaining time Upper : Date max. demand measured
Middle : Predicted value Middle : Load factor Middle : Time max. demand measured
Lower : Present value Lower : Present value Lower : Max. demand value
● Data capturing (Data is saved automatically without user intervention.)
< Operation in the demand interval of this instrument >
