Am I missing something? ('0' reading vs resistance reading on volt meter)

[highpass]

What is the difference between these readings?

I have a battery powered 510 volt meter coming (the one available at most vape sites). If it reads 1.5ohm… it is 1.5ohm. Right?

I read a post elsewhere wherein a microcoil read "0.8ohm at '0' and 1.5 at resistance"… whatever that means.

Huh, Resistance and ohms are the same thing. It can't be 0.8 ohms and have a resistance of 1.5, micro or not. That is someone that has no clue in what they are talking about.

Some meters have the ability to move the decimal point for more accurate readings. As in volts/millivolts or ohms /megohms. Perhaps that is what they are referring to.

Ok this was explained to me.. the base reading of the meter was 0.8. The reading with coil was 1.3. So the actual resistance of the coil is 1.5 - 0.8 = 0.7

Case closed!

That's more reasonable. There is always going to be an inherent resistance In the meter. If you touch the probes together it will give you the baseline as to which you subtract from the reading to get your final resistance.

To be honest, I should've figured that out on my own… not just the mention of "0 reading" but the simple math of it alone

Does this come into play in those 510 meters sold at vape sites? you'd think this already accounted for right

[IMEDICx90]

Those actually don't measure their own resistance due to the nature of the connector. It provides an "exact" zero when reading the coil and so far is accurate for me within a 100th or the actual reading from a multimeter .

Ahh perfect. Cheers

yes I can see that.
