I want to remove the (Measurement result / FFT result /
Help contents) from the display.
To clear automatic measurement results, press the Measure key,
Select Remove Measurement and choose Remove All. See page 73.
To clear individual measurements from the screen, press the
Measure key, select Display All and choose Display None. See page
75.
To clear FFT result, press the Math key twice. See page83 for details.
To clear Help result, press the Help key again. See page55 for

The waveform does not update (frozen).
Press the Run/Stop key to unfreeze the waveform. See page 62 for
details.
If this does not help, the trigger mode might be set to Single. Press
the Single key to exit Single mode. See page 62 for trigger setting
details.
The probe waveform is distorted.
You might need to compensate the probe. The input impedance
may also have to be changed to suit your probe. For details, see
page 191. Note that the frequency accuracy and duty factor are not
specified for the probe compensation waveform and therefore it
should not be used for other reference purposes. Also remember to
set the impedance to 1MΩ.
Autoset does not catch the signal well.
The Autoset function cannot catch signals under 30mV or 20Hz.
Please use the manual operation. See page 61 for Autoset details.
