The M class I believe does follow a power curve against the resistance rise
With the wrong starting locked resistance if too low power delivery would be lower & end temp compared to setting
Too high a dry hit may be on its way with more power being sent to the coil & exceeding the TP setting
Something I have not checked is once the atomiser has been locked in does it fire a dead short or below its 0.05 limit
Need to get myself a dna40 to compare still
That's what I got, too low. No vapor and I was not happy -- Doh! I forgot to push those two stupid buttons again but now the coil is too hot for an accurate resistance reading and . . . Lol.
