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, three­wire; 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.
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.

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.

Select the wiring system to match the actual wiring of the circuit under measurement. he method in which the
Σ functions (wiring unit measurement functions) are determined varies depending on the wiring system. If the
selected wiring system does not match the wiring of the actual circuit, measurements and computation will not be correct.

Settings of Elements Grouped in a Wiring Unit
If a wiring system other than 1P2W is selected when the measurement range, valid measurement range, or sync source settings of each input element are different, these settings are changed in the manner described below:
• When range Σ link is set to on, the measurement range is set to the greatest of the measurement ranges of
the input elements assigned to the same wiring unit. The external current sensor input range has precedence over the direct input current range.
• When range Σ link is set to on, The auto range on/off settings are changed to match the setting of the
input element whose measurement range is highest. If multiple input elements are set to a common highest measurement range, the setting of the input element with the smallest input element number takes precedence.
• When range Σ link is set to on, in the valid measurement range settings, all measurement ranges are enabled
(selected).
• The sync source, line filter, frequency filter, and the group of the harmonic measurement input element are set to the settings of the input element with the smallest input element number among the input elements assigned to the same wiring unit.
At the same time that you press 1 to 7 (ELEMENTS) to select the element that you want to set the voltage or current range of, the keys of the input elements that have been assigned to the same wiring unit illuminate.

External Current Sensor Range and Conversion Ratio Configuration Example
When you measure a current with a maximum value of 100 A using a current sensor that produces 10 mV
when 1 A of current is flowing, the maximum voltage that the current sensor produces is 10 mV/A × 100 A = 1 V.
Therefore, configure the settings as indicated below.
• External current sensor range: 1 V
• External current sensor conversion ratio: 10 mV/A
• When you want to divide the external current sensor output by the conversion ratio and read the current of the circuit under measurement directly, turn the external VT/CT scaling feature off. If the feature is turned on, the value will be further multiplied by the CT ratio.
• When you are measuring a signal other than a sine wave (such as a distorted wave), you can obtain accurate measurements by selecting the smallest measurement range that does not produce any of the conditions below.
• The input peak over-range indicator at the top of the screen illuminates or blinks in red.
