For 3-Phase 4-Wire Y measurements using three current sensors:
Connect the N test lead to the Neutral conductor
Connect the V1 test lead to the L1 phase conductor
Connect the V2 test lead to the L2 phase conductor
Connect the V3 test lead to the L3 phase conductor
Connect the I1 current probe to the L1 phase conductor.
Connect the I2 current probe to the L2 phase conductor
Connect the I3 current probe to the L3 phase conductor
Check that the current arrow on the sensor points towards the load.
This ensures proper phase angle for Power Measurements and other
phase-sensitive measurements.

For 3-Phase 3-Wire Balanced Y measurements using one current sensor:
Connect the V1 test lead to the L1 phase conductor
Connect the N test lead to the Neutral conductor
Connect the I1 current probe to the L1 phase conductor
Check that the current arrow on the sensor points towards the load.
This ensures proper phase angle for Power Measurements and other
phase-sensitive measurements.

Balanced measurements using one current sensor:
Connect the V1 test lead to the L1 phase conductor
Connect the V2 test lead to the L2 phase conductor
Connect the I3 current probe to the L3 phase conductor
Check that the current arrow on the sensor points towards the load.
This ensures proper phase angle for Power Measurements and other
phase-sensitive measurements.
