Hi guys, It bothers me alot my therion DNA 75 is brand new but when i opened it to use it the first thing that bothered me is that there is no VOLT reading on the screen instead there is the ---F and KA at the bottom. Im not sure if this is normal but i have been using other DNA 75 and DNA 200 mods and i dont see this problem. Can someone tell me how to fix this. I just want to the normal setup which is Ohms VOLTS and amp. Please see attached pic for my problem.
