Check if the waveform is false: it is easy for us to regard the
false waveform as the real when a high frequency signal is
connected to the instrument. You’d better make sure that the
current time base is correct.
(3) Check the trigger type: “Edge” trigger suits to general signal and
“Video” trigger suits to video signal. Only in correct trigger type
can the waveform stably display.
(4) Change the setting of trigger holdoff.
5. No display after pressing
:
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 vertical center or change the trigger Mode to “Auto”.
Note:
Press “
” could automatically replace the above setting.
6. The waveform displays like ladder:
(1) The horizontal time base may be too low, you can increase it to
improve the horizontal resolution so as to make 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. USB storage can’t be recognized:
(1) Check if the U disk can work normally.
(2)
Make sure that the U disk being used is of flash type, the
instrument does not support USB 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 are no larger than 4 G.
(4) Restart the instrument and then insert the U disk to check.
(5) If it is still in abnormal use, please contact with PINTEK.
