203
Voltage drop trigger will be dis-
abled.
Voltage sag triggering is disabled when the timebase
is outside of the range 100 µs to 50 ms/div. Change
the timebase so that it is with this range.
The trigger cannot be set when the input mode is ef-
fective value.
204
Measurement range changed.
When [Type]-[Upper/ Lower] is selected, the mea-
surement range is automatically changed to match
the upper and lower limits.
230
Recording time has been changed
due to memory limit.
Increasing the number of measurement channels
has decreased Internal buffer memory waveform
data capacity.
231
Pre-Trigger span changed.
If the recording interval and recording time are
changed, a warning may appear because the time
that can be set for the pre-trigger changes.
232
Recording and Pre-Trigger spans
changed due to waveform memo-
ry limit.
If the recording interval is changed, a warning may
appear because the recording time and the time that
can be set for the pre-trigger changes.
236
File partition period was changed.
The segment time span has been changed in re-
sponse to changing the recording interval.
237
File partition time was changed.
The segment time span has been changed in re-
sponse to changing the recording interval.
238
Unable to set CSV auto-save with
the current record interval.
If you select [CSV(realtime)] or [CSV + Calc] for au-
tomatic saving, set the recording interval to 5 ms or
longer.
239
CSV auto save has been set. Un-
able to set the specified record in-
terval.
To perform measurement at the specified recording
interval, set auto save to other than CSV saving.
245
The reservation settings are in-
correct.
Confirm the schedule settings.
246
When using real-time save, envel-
oping, and numerical calculations
simultaneously, the recording in
-
terval cannot be set to 100μs or
200
μs.
Set the recording interval to 500 µs or longer.
301
No waveform data.
No waveform data is preset, so data saving and cal-
culations cannot be performed. Press START to
start acquiring measurement data.
302
Confirm the A-B cursor position.
The A/B cursor positions are invalid (out of waveform
range). Check the cursor positions.
303
No numerical calculation data.
Execute numerical calculation (p. 177)
304
Invalid event mark.
Try moving to an event mark that is not in memory.
401
File processing error.
An unexpected fault occurred while processing a file
on the removal storage. Turn the power off and back
on.
