5. No display after pressing RUN/STOP:
Check whether the trigger Mode is “Normal” or “Single”, and if the trigger
level exceeds the waveform range. If yes, set the trigger level to the middle
or change the trigger Mode to “Auto”.
Note: press AUTO could automatically replace the above setting.
6. The waveform displays like ladder:
(1) The horizontal time base may be too low, you could increase it to
improve the horizontal resolution so as to obtain a good waveform
displaying.
(2) The lines between the sample points may also cause ladder-like
displaying if the “Type” in menu of “DISPLAY” is “Vectors”. Please turn
the “Type” to “Dots” to solve the problem.
7. U disk can’t be recognized:
(1) Check if the U disk can work normally.
(2) Check if the USB Device interface can work normally.
(2) Make sure that the U disk being used is of flash type, the instrument
does not support U disk of hardware type.
(3) Make sure that the capacity of the U disk is not too large. It is suggested
that the capacity of the U disk matches to the oscilloscope is no larger
than 4 G.
(4) Restart the instrument and then insert the U disk to check it.
