I just got a therion dna75c squonk and it is reading resistance so wrong. My coils on ohms reader is 0.28 and the reading on my therion is .530. Why won't it read correctly and Everytime I lockt thenunlock device it asks if it's a new coil at this price there is no way this is normal my coils are taking forever to heat up like 3 to 4 seconds to get good vapor. Please help
