I have looked for an answer and can't find one. If this is a repeat question. I am sorry. My passthrough for my pen is acting weird. If I activate the the passthrough without an atomizer attached, It acts normally, with a proper cutoff time. If I connect it with an atomizer, it activates for about 1.5 seconds, then gives a bright flash on the passthrough, then quits. I have never seen this before. Any ideas?
