4. Setting the Unit (Unit Operation)
4-13
(12) The Number of Channels to Use (USECH)
Specifies the number of channels to use. The same number of dedicated CTs must be set.
The range of selection (Options):
1CH / 2CH / 3CH
Initial value: 1CH
(13) Measurement Target Circuit (TYPE)
Select the phase and wire configuration of the circuit to be measured. The items displayed
for selection varies depending on the number of channels to use (USECH).
The range of selection (Options):
・When the number of channels (USECH) is 1CH:
1P2 (Single-phase, two-wire) / 3P3 (Three-phase, three-wire)
・When the number of channels (USECH) is 2CH:
1P3 (Single-phase, three-wire) / 3P3 (Three-phase, three-wire)
・When the number of channels (USECH) is 3CH:
3P4 (Three-phase, four-wire)
Initial value: 3P3
(14) Dedicated CT Type (CT)
Used to select the type of the dedicated CT to use. Make sure that the type of the CT to use
is specified.
The range of selection (Options):
5A / 50A / 100A / 200A
Initial value: 100A
(15) Voltage of Measurement Target (VOLT)
Specifies the effective voltage in the circuit to be measured. Make sure that a correct value
is specified since it is used to obtain the current value in the circuit.
The range of selection (Numeric input):
1.0 to 9999.9
Initial value: 220
