TPR-3005-2D labor tápegységhez keresek kapcsolási rajzot.
Ha van valakinek kérem ossza meg.
Egy technikumban tanítok és vélhetően az egyik h*** gyerek a két kimenetet szembe fordította.
A tápegység rövidzárlat védett feszültség generátoros üzemmódban, valamint a kimenő áram szabályozható áramgenerátoros üzemmódban, de a hülyeség ellen nincs védelem.
Bekapcsoláskor az egyik tápegység részen nem állítható be kimenő feszültség és az áram felvétel felugrik 4-5 A-re.
Vélhetően a kimeneten valami rövidzárlatot csinál.

Hello to everybody,
I have bought a defective Gould oscilloscope DSO420. At the beginning of the repair the power fuse was blown immediately after inserting the power plug: The RF-filter connector was shorted. Okay, ignore the RF-filter for now.
Some leaked capacitors were within the power supply, all renewed as well as the NiMh accumulator.
Now most of the scope is running:: All LED at the front as well they are switchable and the screen of the scope was lightened th but only a vertical line is shown. No horizontal deflection at all.
The circuit I have attached, all semiconductor are renewed, no change. The electrolytics are renewed, no change. Allways a vertical stroke. Does anyone have an idea?
Regards from Hamburg
Jens
