When vertical position is zero and N ≥16 :
± ( x reading + div + mV) and mV/div~ mV/div is selected;
± ( x reading + div + mV) and mV/div is selected;
± ( x reading + div + mV) and mV/div~ V/div is selected;
When vertical position is not zero and N ≥16 :
± [ x (reading + vertical shift reading) + ( x vertical shift reading)] + div). Set from
mV/div to mV/div plus mV;
Setup value > 200mV/div to
20V/div plus 50mV.
