5.2 Calculating Electric Power

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).
•To delete a setting, click it then click the

[Delete]

button.

3. Click the

[Execute]

button.

(Calculation results are saved.)

Note: Click the

[Finish]

button to close the

[Power Calculation]

dialog box.

5.2 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]

[3P3W]

to select

the appropriate calculation formula.
