Basic Troubleshooting
The commonly encountered failures of the oscilloscope and their solutions are listed below. If the
following problems occur, locate and resolve the problems according to the following steps. If the
problems still persist, contact
RIGOL
and provide your instrument information to us.
1. When I power on the instrument, the instrument stays black and does not display
anything.
(1) Check whether the power switch is really on.
(2) Check whether the power is correctly connected.
(3) Check whether the fuse is blown. If you need to replace the fuse, use only the specified fuse
that conforms to the product.
(4) Restart the instrument after finishing the above inspections.
(5) If the problem still persists, please contact
RIGOL
.
2. No waveform of the signal is displayed on the externally connected screen.
(1) Check whether the probe is properly connected to the item under test.
(2) Check whether there are signals generated from the item to be tested (you can connect the
probe compensation output signal to the faulty channel to locate the problem, and then
determine whether the channel or the item to be tested has a problem).
(3) Resample the signal.
3. The display of waveform is ladder-like.
(1) The horizontal time base might be too low. Increase the horizontal time base to improve the
display effects.
(2) If the display type is "Vector", the lines between the sample points may cause ladder-like
display results. Click on the function navigation icon
at the lower-left corner of the
screen to enter the function navigation. Click on the "Utility" icon to enter the utility
setting menu. Click Type continuously to select "Dots".
4. The USB storage device cannot be recognized.
(1) Check whether the USB storage device can work normally.
(2) Make sure the USB storage device used is FAT32-format Flash storage type, as this
instrument does not support USB3.0 and hardware storage type USB storage device.
(3) Check whether the capacity of the USB storage device is too large. It is recommended that
the capacity of the USB storage device should not exceed 8 GB for this oscilloscope.
(4) Restart the instrument and insert the USB storage device to check it.
(5) If the USB storage device still cannot work normally, please contact
RIGOL
