Hi Even My 6074BE Oscilloscope has many H/W S/W Errors..

My Channels show 314mV When probes are not ...

Hantek 6254BD

Did the self-calibration routine several times - no change.

open input, setting at 20mV shows 17.6mVolt background noise
open input, setting at 500mV shows 31.4mVolt background noise
open input, setting at 5V shows 314mVolt background noise

Same signals if the input is short with a modified BNC connector.

Connected the scope with the probe to the probe compensation connector,
(probe was set to 1:10) shows the noise in the squarewave too.

So, the 314 seems to be a magic number ;-)
