How to Monitor Power Only?
From the Voltage and Current screen menu, click on the Power button located at
the bottom of the screen.The Real Time Power screen will appear as shown
below with the following information: Real Power: P (kW); Reactive Power: Q
(kVAR); Apparent Power: S (kVA); True Power Factor: pF; and the displacement
power factor: dPf. To return to the previous screen, click on the Back button.
3- Phase 4-wire, 60Hz System Using 1000A Clamp
• Once you have the DM-4 connected with your electrical system, you can follow
the same steps from paragraph 4.3 to paragraph 4.4.1.
• Select 3Ø4W, 60Hz, 1000A and then click OK.
• The Voltage and Current screen should display the readings for all three phases
as shown above.
• You can access the readings for voltage, current and power with their respective
waveforms and harmonics tables as described on “How to monitor voltage only?”,
“How to monitor current only?”, and “How to monitor power only?” in paragraph
4.4.1 for the 1Ø2W system.
