Wiring Systems (For procedures, see section 2.1)
The wiring systems that you can select vary depending on the model.
WT310E and WT310EH
The WT310E and WT310EH are only equipped with one input element. You can measure single-
phase,two-wiresystems.Becausethereisonlyoneinputelement,youcannotselectdifferentwiring
systems.
WT332E (Two Input Element Model)
The WT332E is equipped with two input elements (element 1 and element 3). On the WT332E, you
can select the following wiring systems.
Wiring System Description Elements
1P3W Single-phase, three-wire Element 1 and element 3
3P3W Three-phase, three-wire Element 1 and element 3
The measured data when a single-phase, two-wire system (1P2W) has been specified is the measured
data for elements 1 and 3.
The measured data for a single-phase, two-wire system will be measured correctly regardless of which
of the above wiring systems you select.
WT333E (Three Input Element Model)
The WT333E is equipped with three input elements (element 1, element 2, and element 3). On the
WT333E, you can select the following wiring systems.
Wiring System Description Elements
1P3W Single-phase, three-wire Element 1 and element 3. Element 2 is 1P2W.
3P3W Three-phase, three-wire Element 1 and element 3. Element 2 is 1P2W.
3P4W Three-phase, four-wire Elements 1, 2, and 3
3V3A Three-voltage, three-
current method
Elements 1, 2, and 3
The measured data when a single-phase, two-wire system (1P2W) has been specified is the
measured data for elements 1, 2, and 3. The measured data for a single-phase, two-wire system will
be measured correctly regardless of which of the above wiring systems you select.
