8.4 Example Measurement
The following is an example of measuring the efficiency.
In either the 3P3W or 3V3A connection mode of the 3193, the active power
(
P
) of a 3
φ
3W system is found by the two-power calculation method, and
the efficiency calculation result is also the same.
When channel 1 is the input and channel 2 the output
Input: 1P2W, AC mode / output: 1P2W, DC or AC+DC mode
P

Measuring the efficiency of a single-phase power converter (switching power
supply etc.)
When channel 1, 2 are the input and channel 3 the output
Input: 3P3W, AC mode / output: 1P2W, DC or AC+DC mode
