WAVE Mode (Refer to fig.11)
Push F2 to view the Current WAVE mode. It shows the waveform of the phase currents.
Push F1 (ChgP) (for 3 Phase modes only) to display values for a different phase.
Current Symbol Description
I1, I2, I3 RMS value of the current of phase 1, phase 2, phase 3 respectively
IN RMS value of the current on the neutral
Ipk1, Ipk2, Ipk3 Peak value of the current of phase 1, phase 2, phase 3 respectively
h01 to h49 Harmonic 01 to harmonic 49
ThdI Total harmonic distortion factor of the current
freq Network frequency
Power (Refer to fig.12)
Displays in real time the RMS value of AC/DC voltages, their peak and ThdV values, and their
waveforms, the RMS value of AC/DC currents, their peak and Thdl values, and their waveforms.
Also, the instrument calculates and displays the value of the phase and total active powers, the
value of the phase and total reactive and capacitive powers, the value of the phase and total
power factors and the displacement power factor cosϕ.
NOTE: The symbols “i” and “c” stand for reactive powers (Q), power factors (Pf) and cosϕ (dpf)
respectively inductive and capacitive.
Push F1 (ChgP) (for 3 Phase modes only) to display the other power measurements:
Push F1 once to view: •
In the 3PH3W mode – Wattmeter phases 1-2 and 2-3 values ♦
In the 3PH4W mode – phase1, phase2 and phase3 values ♦
Push F1 twice to view Peak Energy Demand mode
•
Push F1 three times to view Total 3-phase values •
Peak Energy Demand mode (Refer to fig.13)
Push F1 three times while on the initial Power screen to view the Peak Energy Demand mode.
This is only available for 3 Phase modes.
Displays the Max Average value of Active Power and the corresponding Energy, or Max
Average value of Apparent Power and the corresponding Energy measured during the last
(or running) recording. The Average value is calculated during the integration Period of the
recording. It also shows the corresponding Active Energy, Peak Date, and Time.
Push F1 (ChgP) (for 3 Phase modes only) to display the other power measurements:
Push F1 once to view Total 3-phase values •
Push F1 twice to view: •
In the 3PH3W mode – Wattmeter phases 1-2 and 2-3 values ♦
In the 3PH4W mode – phase 1, phase 2 and phase 3 values ♦
Push F1 three times to view Peak Energy Demand mode
•
Push F3 to display Active Power and Active Energy values.
Push F4 to display Apparent Power and Apparent Energy values.
WAVE Mode (Refer to fig.14)
Displays the waveform of the phase currents and the phase (or phase-to-phase) voltage.
Push F2 to view the power WAVE mode.
Push F1 (ChgP) (for 3 Phase modes only) to display values for the phase:
In the 3PH3W mode – Wattmeter phases 1-2 and 2-3 values ♦
In the 3PH4W mode – phase 1, phase 2 and phase 3 values ♦
