3.6.6 DC Power Networks

3.6.6.1 DC 2-Wire

For DC 2- Wire measurements:
■
Connect the terminal N test lead to the common
conductor
■
Connect the terminal V1 test lead to conductor +1
■
Connect the terminal I1 current probe to conductor +1
Ensure that the current arrow on the sensor is directed towards
the load. This ensures proper measurements for power and
other sign sensitive quantities.

3.6.6.2 DC 3-Wire

For DC 3- Wire measurements:
■
Connect the terminal N test lead to the common conductor
■
Connect the terminal V1 test lead to conductor +1
■
Connect the terminal V2 test lead to conductor +2
■
Connect the terminal I1 current probe to conductor +1
■
Connect the terminal I2 current probe to conductor +2
Ensure that the current arrow on the sensor is directed towards the
load. This ensures proper measurements for power and other sign
sensitive quantities.
