⚫
Check whether the coupling mode setting in the channel menu is correct.
6.
If there is no display after pressing
button:
⚫
Check whether the trigger mode is “Normal”, and whether the trigger level is beyond the scope of the
waveform. Center the trigger level and set the trigger mode as “Auto”.
⚫
Check whether the picture is displayed in full screen, and if so, exit the display.
7.
If the display becomes slower after setting average times of sampling:
⚫
If the average times are above 32, it is normal for the general speed to become slow.
⚫
You can reduce the average times.
8.
Staircase waveform is displayed:
⚫
This phenomenon is normal because the horizontal time base is too low, and the horizontal time base
may be increased to raise the horizontal resolution, and then improve the display;
⚫
The display type may be “line”. The connection between sampling points may lead to the display of
staircase waveform. This problem can be solved by setting the display type as “point” display mode.
9.
There is persistence of vision in waveform display:
⚫
This phenomenon is normal because the persistence time may be set too long, and the waveform
persistence shows persistence of vision;
⚫
The reason may be that sampling mode is set to envelope of sampling, and the sampling mode can be
modified to normal waveform for normal display
10.
During measurement, the measured value is displayed as -----:
⚫
This phenomenon is normal. When the channel waveform displays beyond the waveform display area,
the measured value is displayed as -----. If the channel vertical sensitivity or vertical position is adjusted,
the measured value can be displayed correctly;
⚫
This phenomenon is normal. When there is no full-cycle waveform in the waveform display area, the
measured value may be displayed as -----. If the time base is adjusted, the measured value will be
displayed correctly.
⚫
This phenomenon is normal, and the measured value of the FFT waveform is displayed as -----.
11.
When viewing pictures, no pictures are displayed:
⚫
Check whether the USB option in the settings is set as the USB storage device. If it is the USB storage
device, please change to other options.
12.
The oscilloscope will be black if there is no operation for a period of time:
⚫
Check whether the standby time setting in the setting is disabled; if it is not disabled, it will
