-2. [VIEW] screen
(1) Waveform display
Displayed screens 1. Voltage/Current : 2-segment split display (voltage waveform (U1 to U4), current waveform (I1
to I4))
2. Voltage 4 channels: 4-segment split display (voltage waveform (U1 to U4))
3. Current 4 channels: 4-segment split display (current waveform (I1 to I4))
Display axis selection Vertical axis: Choose from ×1/3, ×1/2, ×1, ×2, ×5, ×10, ×20, and ×50.
Time axis: 5 ms/div., 10 ms/div., 20 ms/div., or 40 ms/div.
Cursor measurement CH1, CH2, CH3, and CH4 waveform cursor values and cursor times
Scroll function Vertical axis scrolling, horizontal axis scrolling
(2) Harmonic display
Displayed screens Vector/harmonic graph/harmonic list
Vectors 1. Level: Vector d harmonic RMS value display
2. Content percentage: Vector d Harmonic content percentage display
3. Phase angle: Vector d Harmonics phase angle display
Display format Display of harmonic voltage RMS value and harmonic current RMS value vectors
Display of harmonic voltage and current content percentage vectors (including fundamental
wave)
Display
parameter
By order: Harmonic voltage RMS value, content percentage, phase angle, and harmonic cur-
rent RMS value or phase angle
Fundamental wave: Frequency, voltage unbalance factor, current unbalance factor
Vertical axis
display format Choose from LINEAR or LOG.
Selection of
phase angle
display Choose from ±180° and +360° lag.
(When +360° lag has been selected, the user can choose the reference source [U1 to U3, I1
to I3]. The selected reference source will be used as the reference [0°] for each order. When
±180° has been selected, the U1 fundamental wave is used as the reference source.)
Order selection Order cursor values (during 400 Hz measurement, 0th to 10th orders)
Harmonic graph
Display format
3-segment display
Area 1: harmonic voltage RMS value, content percentage, phase angle, inter-harmonic voltage
Area 2: harmonic current RMS value, content percentage, phase angle, inter-harmonic current
Area 3: harmonic power, content percentage, harmonic voltage/current phase difference
Display of inter-harmonics is not available during 400 Hz measurement.
The voltage and current RMS value display incorporates high-order harmonic components.
