7. Start Measurement
Press the START key.
The green LED lights, and the Waveform screen appears.
The instrument’s measurement status is displayed on the Status bar.
Recording does not occur until the specified trigger criteria are met.
The waveform is displayed.
(If the [Roll Mode] setting is [Off] on the Status setting screen, the
screen displays acquired data in quantities determined by the specified
by the recording length.)
Every time data is acquired, it is saved to the PC Card and the “Trigger
Wait” state is resumed.

In this measurement case, 50 divisions of data (including the pre-trigger setting of 10% of the 50-div
i-
sion recording length) are recorded when the voltage is 280 V (197.99 Vrms) or less, at 5 ms per div
i-
sion on the horizontal time axis.
Settings can be changed and the waveform can be scrolled while recording.
Recording restarts when setting are changed. (“

See "3.3.6 Starting and Stopping Measurement" in the Instruction Manual
Press the STOP key.
8. Finish Measurement
See "3.3.6 Starting and Stopping Measurement" in the Instruction Manual
• Pressing Once: Recording stops when finished acquiring data for the recording length.
• Pressing Twice (Halt): Recording stops immediately.
If you halt while awaiting a trigger, no waveform is displayed. (However, with the Memory function
,
the waveform does appear if the recording length is shorter than half of the maximum recordin
g
length and a trigger event has occurred before the Halt command.)
What about these situations?
You can disable the keys to
prevent inadvertent opera-
tions
Hold both CURSOR keys simultaneously for three seconds. “Key Lock”
appears under the clock display while the key-lock state is enabled. To cance
l
key-lock, hold the keys again for three seconds.
When "Trigger Wait" contin-
ues to be displayed and no
waveform appears
If the trigger criteria are not met, no waveform is displayed (⇒ p. A10).
If you need to display the waveform, execute a forced (manual) trigger.
(FN Mode: F6 key)
To view part of the waveform
that is not visible while re-
cording
Use the SCROLL controls to scroll the waveform. When turning the inner Jog
or outer Shuttle knob, the [Scroll Trace] button appears at the left. Press the F1
[Scroll Trace] key to return to display of the currently recording waveform.
Refer to the scrolling methods: "2.3.3 Viewing Recorded Data" (
⇒ p. 35)
To change settings while re-
cording
Timebase, recording length, input channel and trigger settings can be changed
from the Waveform screen.
