• Ready Data Success! : Read setup data or waveform data from
the internal memory of the oscilloscope or USB flash was
successful.
• USB Flash Drive isn’t connected! : When the “Save To” option
is set to “File” or the “Print Key” option is set to “Save Picture” in
“Save/Recall” menu , press the “Save” option button or the
“Time/div” knob before inserting the USB Flash Drive to the USB
Host port or this will appear on the screen.

Troubleshooting
1. After the oscilloscope is powered on, the screen remains dark.
Please do the following:
1. Check the power cable’s connection.
2. Check the rear AC main input switch located above the
AC input receptacle. Make sure it is in the ON ( | )
position.
3. After the inspecting above, restart the oscilloscope.
2. If there is no signal wave in the screen after probing DUT for a
signal, please do as follows:
1. Check whether the probe is connecting with the signal
cable or not.
2. Check whether the signal cable is connected with the
BNC connector or not.
3. Check the probe whether it’s connected with the device
under test (DUT) or not.
4. Check the tested DUT to see if it produces the signal or
not.
5. Try to probe the DUT for signal again.
3. If the value of the tested voltage is 10 times higher or lower
than actual, please do the following:
Check the attenuation quotient whether it matches the
probe attenuation proportion or not.
4. If waveform display is not stable, please do the following:
1. Check the signal source on the trigger interface whether
or not it matches the signal channel.
2. Check the trigger mode: normal signal should use the
