YiHi chip inaccurately reading resistance

My sigelei 50 does this intermittently also. Not the atty or 510 screw adjustment causing it. Was fine for 5-6 months then the problem started. Figured I got my money's worth and moved on.

My Sig mini was doing this to my blue KF4 the other day. Wrapped a perfect 2.5mm 1.4 ohm coil on the Coil Master, read fine at 1.4. Wicked, juiced, and put the tank on and it started freaking out. It settled itself after awhile but once reassembled, my 1.4 now hits 1.6..
