    Hello I have just purchased the st-16b 10 MHZ scope from Sinometer.

    I am inputing 2 volts dc at 1volt/div and I see the line on the scope at 2 major squares above the x axis. This is okay, however, if I switch to 2 volts/div, the line now goes to two little segments above the x-axis which indicates 0.4 volts which is wrong. It is supposed to be at 1 major square above the x-axis, right?

    Its like I have to re-ajust the horizontal base line every time I change the voltage/div deflection scale. Is this normal in every scope or is it that I am missing something?

    All help much appreciated!

    Hi,

    No, that's not the way it should work. If you've established the position of the trace at 0 volts, then the deflection should be from that point. If your vertical sensitivity switch is miswired, it might produce such results. What happens with other settings?

    If you bought it new or even used there should be a warranty policy unless you bought it "as is". If it's under warranty, list everything you find wrong & contact either the mfgr. or seller's customer service.
