Thanks for the Video. Does your 30mV , 100mV, and 300mV Range ,in Scope mode , work without troubles ?

I know the manual and I read it weeks before..... The trouble is ,the Specs say oszilloskope works in ACV Mode , but on mine thats not true. Theres a DC offset in mV Mode which makes use of mV range nearly useless. Second fault is the shown voltage in respect of the frequency . Levels above 3to4 khz are not shown with correct Level.in V Range everything is fine. My GDVA GD 188 , which has also a symmetric 4mm input shows correct values ! My Owon HDS 242 also shows the correct level....Guess maybe there is an impedance problem.
