Mod reading coil .05 ohms lower

[RCP1991]

I have three mods. A Geek Vape Aegis, a Hohm Tec Hohm Slice, and a Pico 25. Today I put a new build in my Ammit Dual, did some calculations and it looked like the build was supposed to come out around 0.28.

I put the atty on the Pico (which is my daily carry mod) and it read 0.21. I checked my build and everything looked okay. I vaped it for a bit and it was fine but the ohm reading was annoying me. So, I decided to put the atty on my other mods and both mods read the cool coils at 0.26 ohms.

I'm wondering why this is occurring and if it is dangerous and/or messing up my temperature control settings (I use ss316 coils and typically vape around 450* with a 60 watt ramp up).

Thanks.

These devices are inexpensive. They are not super accurate

Fair enough, but I'm more interested in what this is doing to my device, vape consistency, and batteries.

1. Is it safe? In other words is vaping at the 0.05 lower ohms going to put more stress on my batteries. Should I not use the Pico?

2. Is the tc vape still close to the temp I am setting it at or are the lower ohm reading causing it to be hotter or colder?

3. Is there anything I should do?

A slight variance between power devices isn't uncommon, it shouldn't mess with TC operation as long as you 'lock' resistance when cold.

Resistance is irrelevant as long as it is within a given power devices operation range as far as battery amp demand goes when using a regulated power device.

.05 ohm is not a lot

1. It should be safe as the mod should not fire below an unsafe level - take that for what it's worth.
2. TC should work as long as it's set by the mod's instructions, if set up with what the mod is reading then it shouldn't matter what other mods say.
3. Not worry about it, I'd bet with other batteries and/or mods, you'd get even more different readings.

Some mods will read higher than others due to internal resistance and/or just being inaccurate. If a calculator says it is .25 and other mods are reading the same (close to it) I'd imagine it's right and the other mod is just not as accurate for some reason.

Try unscrewing it until it just reads an atomizer is attached, it'll probably show a different amount than when fully screwed on. I've had many that change resistance readings when an atty is tightened down.

.05Ω = five one hundredths of an ohm.
Dirty 510 connection threading or positive pin can make more difference than that.

It wouldn't be unusual to have to use different ramp up/watt settings & different temp setting using different power devices to get an identical vape.
