5.1 Voltage assignment
If the phase and wire type has been set to 1-phase 2-wire voltage selected (1P2W2) or 1-phase 3-wire composite
(1P3W2), then you need to set the voltage for the 1-phase 2-wire circuit doing the measuring. Set either R-N phase
or T-N phase if the input voltage is AC100V, and set R-T phase of the input voltage is AC200V.
As the following diagram shows, the 1-phase 2-wire circuit for which the voltage allocation is set is circuit A, circuit B,
circuit C, and circuit D for 1P2W2 wiring and circuit C and circuit D in the 1P3W2 wiring diagram.
You need to allocate voltage for each circuit.
■
Set the voltage assignment (Ex.: set the voltage assignment for circuit C to V_R-T)
If a measured value is displayed, press and hold the [<</MODE] key and enter your password to switch to the setting
mode.
1
Press the [<</MODE] key to move to the settings category display screen for circuit C.
2
From the circuit C setting item, press the [
][
] keys to move to "Voltage assignment (MENU C5)".
3
Press the [ENTER] key to enter the setting mode.
4
Press the [
][
] keys to select "V_R-T".
5
Press the [ENTER] key to confirm your selection.
Information
• The MENU No. for allocating voltage for circuit A is "A5".
• The MENU No. for allocating voltage for circuits B to D are circuit B "B5" , circuit C "C5", and circuit D "D5".
