I don't know what the atty or PV is - and has been said, that would certainly help with diagnostics - but in simple terms, your PV is reading a resistance value below it's minimum range of operation/maximum current output... a value which should be found in your owners manual, or on-line.
It doesn't necessarily mean your resistance is actually 0.1Ω or less... it only means that your PV chipset programing is detecting a near dead short, and will not attempt to supply current.
The issue may be in the atomizer, or it may be a fault in the PV. Try a different, "known good" atomizer... if you get an accurate reading, perhaps you do have a near dead short in the atty.
