Vt box 250 - Can't read under 0.008 ohms

[eziotroito]

Hi everyone,

My device can't read under 0.008 ohms. I noticed this while shorting atom to know my mod resistance. No matter if I change atomiser or if I change wire (for instance I used a thick copper wire) but when I attach it, it start to read for example 0.011 and while I screw it began to go under and under, while the connection become more stable, until... 0.008 and then only "?". Picture attached. Please help!

Shod I try to check 510 connector or maybe it could be a fault in the board?

 

Thanks

This is a known issue. Nothing wrong with your device!

Thank you, 

Could you please help me find the thread or some keys words to find it?

Also, a lot of other people CAN read 0.005 without problems, so... I don't know if it's some batches hardware issue or a software issue

Thanks

It has been a know issue since one of the firmware updates. If you are trying to measure the internal resistance of you mod, the here is a workaround that a lot have gotten to work quite well....https://forum.evolvapor.com/topic/65594-mod-resistance/?page=3...

Start at about this post & read on....

 

 

 

You can try this..on the last 250 I bought, I too was having the ? when trying to obtain the mod resistance due to the wonky Atomizer Analyzer..took a build that I knew the ohms...ran the analyzer & subtracted..in this instance, the build was .07?...this may help you get a closer idea as to your mod resistance...of the 7 DNA devices I have, they range from .003 to .005

   
Just make sure that the coil is cold..
