3 Select the waveform to be the judgment
reference in [Ref].
Setting options (∗. default setting)
Judgment is started using the point at which the
input signal crosses 0 V as the reference
4 Set the frequency of the target commer-
cial power supply in [f] (frequency).
Setting options (∗. default setting)
Sine* Uses the ideal waveform based on the
set frequency and reference voltage as
the reference.
Prev. Uses the waveform one cycle before the
input waveform as the reference. Use
this when you do not want the trigger to
be applied as a result of slight changes.

Input wave-
form (1 cycle)
Judgment is made by comparing
with the previous waveform.
[Prev. (Previous waveform)]
The control range is set for this
portion
5 Set the control range to permit for the
reference waveform in [Range].
Setting options
The level to be set at this time is the instan-
taneous value level.
6 When [Sine] was selected in [Ref]
Set the voltage to measure from the set-
ting options of [Ref volt].
Setting options
The level to be set at this time is the effec-
tive value level.
(The "r" of "Vr" indicates rms (effective value))
Settable range
x1/2 to x2.5 of vertical axis (voltage axis) range
Example: When the vertical axis (voltage axis)
range is 20 V/div: 10 V to 50 V
(20 V/divX0.5 = 10 V, 20 V/divX2.5 = 50 V)
Settable range
x1 to x7 of vertical axis (voltage axis) range
Example: When the vertical axis (voltage axis)
range is 20 V/div: 20 V to 140 Vr
(20 V/divX1= 20 Vr, 20 V/divX7 = 140 Vr
When the data of the measured
waveform is printed, the judgment
area of the one cycle portion in
which the trigger was applied is
also printed.
