Please, waiting for your answer. I had set the attenuation switch of the probe, I had also set the coefficient in the screen (x10, x100, etc)
No solutions
I had uploaded two images.the first one displaying a sinewave with 311 volts peak-to-peak, with vertical scale 20 V/div
the second one is the same, but scale 50 V/div
It is not working vertical scale 50V/div
The probe is 10X

After self-calibration, I have the sinewave displayed at 50 V/div again
The sinewave is 311 Vpp.
As you can see at picture one, it is out of scale
After change to 500 V/div, the picture is still out of scale
After change to 5KV/div, the same
Probe is configurated at 10X
Let me know how to solve this
At last, the calibration square wave 5V is O.K.
