represents ΦU1 – U2, the difference between the fundamental voltage signal of element 1, U1(1), and the
fundamental voltage signal of element 2, U2(1). In the same way ΦUi – Uk, ΦUi – Ii, ΦUj – Ij, and ΦUk−Ik
represent to ΦU1 – U3, ΦU1 – I1, ΦU2 – I2, and ΦU3 – I3, respectively.
2 Setting i to an input element, is the same as setting k to 1 in Φ(k).

What Is a Measurement Function?
Measurement Function
The physical values (such as rms voltage, average current, power, and phase difference) that this instrument
measures and displays and measurement range and other measurement information are called measurement
functions. Each measurement function is displayed using symbols that correspond to its physical value. For
example, “Urms” corresponds to the true rms voltage.
Element
Element refers to a set of input terminals that can receive a single phase of voltage and current to be measured.
This instrument can contain up to seven elements, numbered from 1 to 7. An element number is appended to
the measurement function symbol for the measured data that this instrument displays, so that you can tell which
data belongs to which element. For example, “Urms1” corresponds to the true rms voltage of element 1.
Wiring System
You can specify five wiring systems on this instrument to measure the power of various single-phase and
threephase power transmission systems: single-phase, two-wire; single-phase, three-wire; three-phase, three-
wire; three-phase, four-wire; and three-phase, three-wire with three-voltage, three-current method.
Wiring Unit
The wiring unit is a set of two or three input elements of the same wiring system that are grouped to measure
three-phase power. There can be up to three wiring units: ΣA, ΣB, and ΣC.
Click here.
Σ Functions
The measurement function of a wiring unit is called a Σ function.
For example, “UrmsΣA” corresponds to the average of the voltages of the input elements that are assigned to
the wiring unit ΣA. The average value represents the true rms value.

Saving Setup Data (Save Setup, SAVE(SETUP))
You can save the setup data of this instrument to the specified storage device. The date, time, and
communication setup parameters are not saved.
The extension is .SET.
File List (File List)
On the file list, specify the save destination. You can perform file operations such as creating folders on the
storage device, deleting and copying files, and changing file names.
Click here.
Auto Naming (Auto Naming)
OFF
The auto naming feature is disabled. The name that you specify using the File Name setting is used. If there is a
file with the same name in the save destination folder, you cannot save the data.
Auto Numbering (Numbering)
This instrument automatically adds a four-digit number from 0000 to 0999 after the common name specified
using the File Name setting and saves files.
Date (Date)
The date and time when the file is saved are used as its name. The file name specified for the File Name setting
is ignored.

Sequence number (0 to 9 then A to Z) for when multiple files
are saved at the same time (second)
A sequence number is appended to the date and time when multiple files are saved at the same time (second).
The number starts at 0 and is incremented by one each time a file is added. The number 9 is followed by letters
of the alphabet.

File Name (File Name)
You can set the common file name that is used when the auto naming feature is turned off or when the auto
naming feature is set to Numbering. The maximum number of characters that you can use for file names and
folder names is 32 characters. The following restrictions apply.
• Of those characters on the keyboard that appears on the screen, the characters that can be used are 0-9,
A-Z, a-z, _, –, =, (, ), {, }, [, ], #, $, %, &, ~, !, `, and @. @ cannot be entered consecutively.
• The following exact strings cannot be used due to MS-DOS limitations:
AUX, CON, PRN, NUL, CLOCK, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, COM1, COM2,
COM3, COM4, COM5, COM6, COM7, COM8, COM9
• Keep the full path name (absolute path from the root folder) within 255 characters. If this is exceeded, an
error will occur when you perform file operations (save, copy, rename, create folder, etc.). When an operation
is being performed on a folder, the full path is up to the name of the folder. When an operation is being
performed on a file, the full path is up to the name of the file.
The following additional restrictions apply when you use the file name auto naming feature.
• If you set auto naming to Numbering, a file name will consist of the characters that you entered for the file
name and a four-character sequence number.
• If you set auto naming to Date, the characters that you entered for the file name will not be used. File names
will only consist of the date information.

The comment settings (Comment) are shared by the menus for saving setup data and storing data.
Saving (Save Exec)
Saves the data to the specified save destination with the specified file name.
Loading Setup Data (Load Setup, LOAD(SETUP))
On the file list, specify a file to load setup data from. The extension is .SET. For information about how to
configure the file list display and how to operate files and folders, see “File List (File List).”
Click here.
Loading (Execute Load)
Loads the data of the specified file.
• If you change the extension of the saved data file, by using a PC or some other device, the instrument will
no longer be able to load it.
• When setup data is loaded from a file, the setup data for each key is changed to match the loaded settings,
and it cannot be changed back. We recommend that you save the current settings before loading different
setup data.
• The date, time, and communication setup parameters are not saved. So even if you load setup data from a
file, the date, time, and communication settings will not change.
• This instrument cannot load setup data that has been saved by a product with an incompatible firmware
version.
• This instrument cannot load setup data that was saved by an instrument with a different element
configuration, different options, etc.

Input Settings (Basic Measurement Conditions, Input (Basic))
You can specify the following items.
• Wiring system (Wiring)
• Selecting the element for setting the measurement range (Element1 to 7, 1 to 7 (ELEMENTS))
• Voltage range (Voltage, VOLTAGE RANGE)
• Auto voltage range (Auto (Voltage), AUTO)
• Current range (Current, CURRENT RANGE)
• Auto current range (Auto (Current), AUTO)
• External current sensor on/off (Ext Sensor)
• External current sensor conversion ratio (Sensor Ratio)
• Scaling (Scaling)
• Line filter (Line Filter)
• Frequency filter (Freq Filter)
• Measurement Period (Sync Source)
Wiring System (Wiring)
The following five wiring systems are available on the instrument. The selectable wiring systems vary depending
on the number of installed input elements.
• 1P2W: Single-phase two-wire system
• 1P3W: Single-phase three-wire system
• 3P3W: Three-phase three-wire system
• 3P4W: Three-phase four-wire system
• 3P3W(3V3A): Three-voltage three-current method
Wiring Unit
Wiring units are sets of two or three input elements of the same wiring system that are grouped together. You
can define up to three wiring units: ΣA, ΣB, and ΣC.
• When there is one wiring unit, that unit is ΣA. You cannot make ΣB or ΣC the first wiring unit.
• When there are two wiring units, those units are ΣA and ΣB. You cannot make ΣC one of the first two wiring
units.
• When there are three wiring units, those units are ΣA, ΣB, and ΣC.
• When there are multiple wiring units, element numbers are assigned to them in ascending order. The element
numbers are assigned to ΣA, ΣB, and then ΣC.
• Wiring units are composed of input elements that are next to each other. Wiring units cannot consist of input
elements that are not next to each other.
• Wiring units cannot consist of input elements that are different types.
Σ Functions
The measurement function of a wiring unit is called a Σ function.
For example, “UrmsΣA” corresponds to the average of the voltages of the input elements that are assigned to
the wiring unit ΣA. The average value represents the true rms value.
