I just got a new AHP Alpha TIG 200x, 2016 version. The pulse dial does not reflect the actual pulse rate which kinda sucks. If I want 1pps, I have to turn the dial to 4pps. 1pps on the dial actually yields something like 1 pulse every 3 seconds or something. I can't tell what it's doing on the high setting, as it quickly gets too fast to count. Had anybody else experienced this?
