10 to 70 Hz X 16 max.
70 tp 140 Hz X 8 max.
140 to 280 Hz X 4 max.
280 to 560 Hz X 2 max.
560 to 4500 Hz X 1 max. (can not be changed)
NOTE
ZOOM
Voltage and current
waveforms can be zoomed.
The zoom area can be
panned by the left and right
cursor keys, and the amount
of magnification set by the
up and down keys. Pressing
the
F4
key switches between
U and I.
FFT
All voltage and current
waveform analysis data can
be graphed. The upper part
is voltage and the lower part
is current. Degree and
frequency can be read by the
CURSOR
and keys.
･
The cycle displayed in one screen is different depending on the PLL
synchronization range. See Chapter 9, "Specifications" for more information.
･
The waveform zero-crossing point is not correlated with frequencies.
･ The waveform starts from a point at which the voltage waveform (or current
waveform) specified as the PLL source waveform crosses the zero value, and
displays the first cycle from the window being analyzed. The other waveforms
are displayed for the same time interval as this waveform.
･
It is not possible to select individual items for display.
･ Because items not displayed are calculated internally at the same time, by
switching to the hold state and switching the screen, it is possible to
display simultaneous parts of other waveforms.
･
The power waveform is not displayed.
･ Only waveforms for channels synchronized to (at the same frequency as)
the PLL source channel are valid.
･ Cursors are not available for data readout.
･
Effective power is not displayed.
･ The vertical axis is fixed as LOG.
･
FFT format can not be selected when sorting is enabled.
･ The vertical axis is fixed as 100% when the FFT format is selected.
