It was an already used coil in an already used tank, both used already on this dna mod.
No hotspots and all screws tight.
Installed at room temp yes.
The coils are a pair of SS316 SSFC's at 4mm ID, 0.16Ω
In Atomizer Analyzer the coil sits at 0.164Ω and every few secs will go up to 0.165Ω briefly then back to 0.164Ω
Here is the screenshot from one of my hadron plus that has this issue. One of my hadron pro's has the issue also but that is a build I did a while ago so I'm going to check the coils first.
