Question

Is it possible to measure power in multiple circuits using the same voltage circuit?

Answer

Although the instrument can only measure power in a single circuit, the desktop application 9745 Line Monitor Viewer can perform the calculation you describe.

1P2W: Up to 12 circuits
1P3W or 3P3W: Up to 6 circuits

Calculations are based on average values taken over an interval (voltage fundamental wave, current fundamental wave, and voltage and current phase differences for each channel). For more information, please see page 81 of the 9475 User’s Manual.
