Approximate electric power is calculated using current measurement data from a
clamp logger.
Calculation results are saved as a new item in the recording file.
1. Select the items, time span, and calculation formula to be used.
2. Specify the voltage, power factor, and units.
•To save the settings, click the [Register] button.
•To apply a registered setting, double click it ("Setting1” in the above screenshot).

Calculating Electric Power
• Electric power calculations are only approximate, so results do not
always equal the true electric power value. Use a wattmeter if accu-
rate power measurements are required.
• There is no way to confirm that a specified data item is really a current
value. Calculation occurs regardless of data type.
Item and range settings
Specify two measured current values
and the time span for calculation.
[Electric Power Type]
Choose [1P2W] , [1P3W] or [3P3W] to select
the appropriate calculation formula.
