• MODE Key (See section 5.2)
Switches the voltage mode and current mode. The mode can be set to true rms value
(RMS), rectified mean value calibrated to the rms value (MEAN), simple average
(DC), or rectified mean value (RMEAN) for the voltage mode and current mode,
separately.
• NUMERIC Key (See section 3.15 and 5.1. For details on the harmonic
measurement (/G6 or /G5 option), see the
Expansion Function User’s Manual
IM760301-51E .)
Displays the screen that shows the numeric data.
• Pressing the ITEM key (explained later) while showing the numeric data opens a
menu for changing the displayed items.
• Pressing the FORM key (explained later) while showing the numeric data opens a
menu for changing the number of displayed items. For harmonic measurement (/
G6 or /G5 option), a list showing the measured values for each harmonic order can
also be selected.
• WAVE Key (See section 3.15 and 6.1 to 6.8)
Displays the screen that shows the waveform.
• Pressing the ITEM key (explained later) while showing the waveform opens a
menu for selecting the displayed waveform or a menu for zooming the waveform.
• Pressing the FORM key (explained later) while showing the waveform opens a
menu for setting the time axis of the displayed waveform, the trigger for displaying
the waveform on screen, the number of divided waveform display windows, the
assignment of waveforms to the divided windows, etc.
