For DC 3- Wire measurements:
Connect the N test lead to the negative conductor
Connect the V1 test lead to con1
Connect the V2 test lead to con2
Connect the I1 current probe to con1
Connect the I2 current probe to con2
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 DC 4-Wire measurements and using three current sensors:
Connect the N test lead to the negative conductor
Connect the V1 test lead to con1
Connect the V2 test lead to con2
Connect the V3 test lead to con3
Connect the I1 current probe to con1
Connect the I2 current probe to con2
Connect the I3 current probe to con3
Check that the current arrow on the sensor points towards the load.
This ensures proper phase angle for Power Measurements and other

For DC 2- Wire measurements:
Connect the N test lead to the negative conductor
Connect the V1 test lead to positive con1
Connect the I1 current probe to con1
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.
