Make sure coil id seated in base firmly. Change mode to temp Ni and reattach tank to mod. Also make sure coil is cool when you reconnect it to mod.
Once it reads the coil correctly, use " lock resistance" feature.  That should do it.

If the tank that came with it reads correctly, the problem may be the subtank base. I have a subtank plus and use nickel coils on it on my evic vtc mini and get exact ohm readings. So there may be something wrong with the subtank coil base.
