The waveform does not update (frozen).
Press the Run/Stop key to unfreeze the waveform. See page42 for
details. For trigger setting details, see page75.
If this does not help, press the CH key. If the signal still does not
appear, press the Autoset key.
The probe waveform is distorted.
You might need to compensate the probe. For details, see page112.
Note that the frequency accuracy and duty factor are not specified
for probe compensation waveforms and therefore it should not be
used for other reference purposes.
Autoset does not catch the signal well.
The Autoset function does not catch signals well under 30mV or
20Hz. Please operate the oscilloscope manually. See page41 for
details.
I want to clean up the cluttered panel settings.
Recall the default settings by pressing the Save/Recall key→Default
Setting. For default setting contents, see page38.
The saved display image is too dark on the background.
Use the Inksaver function which reverses the background color. For

The accuracy does not match the specifications.
Make sure the device is powered on for at least 30 minutes, within
+20°C~+30°C. This is necessary to stabilize the unit to match the
specification.
The SD card slot does not accept my card.
Make sure the SD card is formatted as FAT or FAT32. Try a different
SD card brand if you are still having trouble.
The oscilloscope will not allow a 2M waveform to be saved.
Make sure that only 1 channel is active. Make sure that the signal
has been triggered and that the STOP or Single key has been pressed.
Ensure the time base is slower than 10 ns/div. See page 87.
