My cold ohm readings are almost the same on different devices, which means it's impossible for me to identify resistance abnormalities. Just now, I remade a coil, but after making this coil, I used the temperature control mode of 220 ° C dry burning to remove impurities (without cotton and juice), then reinstalled the cotton and juice and read the cold ohm. Miraculously, everything returned to normal, perhaps because WIREOPTIM's coil had impurities? I'm not sure if it's because of this, as I didn't perform dry burning operations before and occasionally everything worked fine, but most of the time there was no smoke.
There is a fatal issue that when I do not perform dry burning operation, the DNA60c chip cannot perform temperature control normally (with a small amount of smoke or misjudgment of temperature), but it can still maintain normal temperature control on the YIHI SX730 chip. I cannot determine the real reason. Could you please advise me? Thank you, I come from China and use a translator. I hope you can understand,
