I got some informations from Roger and from my distributor from Germany (Atech). The "A" was the curve that doesn't worked, so I took this picture and asked about it. They answered me, that if you open the case, you have to be careful. Often you get close to the selektor and switch without noticing. That was my faultGreat ill see if i can find a cc/cv/off setting. One thing. That first pic of the selector. Looks like an A not a 7. How did you determine the setting was for curve 49/setting 7?
I use a clamp ampmeter (Uni-T UT203) to measure the amps and secondly I got a LEM HAS 200 to count amphours in and out. This shows me the amps on a display, but only two counters (f.e. 12A).Very interestring stuff guys! I guess the trade secret really lies with getting the factory settings for the selector on the left of the board, I am also curious about measuring the current? I understand measuring and adjusting the voltage setting ( right pot) but what do you use to measure the current( the left pot)? In line ampmeter? and does anyone have either the settings or a link to the settings? thanks again. I still have the factory seals on mine and am very hesitatant ( aaafffffraid!!) to open the case!!
