I have an aspire plato, but the ohms keep jumping around. Used it with the 0.4 ohm coils and the hms go from 0.4 to 0.41 to 0.39. When i tried the 1.8ohm coild the ohms jumped from 1.88, 1.87, 1.89, 1.96, 1.79. What could be the issue and what would be causing this. I really like the device and want to continue using it as my EDV, but im skeptical to do so if the ohms keep jumping around.
