Measurement Applications KPM1000
Measuring integrated power
Configuring the KPM1000 settings
p.25
1
Set the voltage and current ranges.
2
Turn the LPF (low pass filter; ConF.1 LPF) on.
p.29
Press CONFIG, and then operate the menu to set this setting to “on.”
Use the low pass filter when you are measuring a comparatively small current (100 mA
or less). This limits the noise that the AC power supply generates and enables correct
measurements.
3
Turn the integration timer (ConF.9 intEG) on.
Press CONFIG, and then operate the menu to set this setting to “on.”
4
Set the integration time (ConF.10 intEG.t).
Press CONFIG, and then operate the menu to set the integration time.
5
Press DSPL B or DSPL D to select the integration display items that you
want to show.
p.22
The display items that you can select are shown in the following table. The selected
display items are shown on the selected displays (before integration starts, “-----” is
displayed).
To display the integration time, press DSPL B or DSPL D to select “h.” The integration
time is displayed as a count down (before integration starts, “-----” is displayed).
Select the necessary items to show on the other displays. The KPM1000 performs
integration even if it is not displaying the integrated values.

• Set the current range to match the maximum load current during the test. For loads that
have large fluctuations in their signals, even if you use the auto range feature, an over-
range may occur during integration.
• If an over-range occurs during integration, the Wh indicator blinks.
• If the waveform’s peak value or RMS value causes an over-range to occur, the OVER V
LED or OVER I LED lights.
• If the active power becomes negative during measurement, check the wiring of the voltage
input terminal. You can fix this problem by swapping the wires that are connected to
terminal U and the ± terminal.
