Not sure if this was already addressed but i couldnt find anything. I've been using my Segelei 100W Plus and after a few days of use i notice something acting different. When i hold the up watt button (+) from below 50 watts i get a .9 above 50 watt to the 100 watt area. like 72.9 or 65.9 and so on. When i first received this product i wasnt getting this. i would start from a wattage from below 50 and hold the up watt button and as soon as it hit 50 or so watts the decimal point would go away. Is this just me? is this normal? couldnt find much information about this.
