Am reusit sa fac vechiul meu multimetru DT-832 (din piata) sa nu mai masoare curentul pe ramura de 10A (a fost simplu credeti-ma). Restul masuratorilor le face la fel de corect ca inainte pe toate functiile inclusiv DCA : adica folosind o baterie obosita cu cca 1V pe setarea de 200mA arata cca147mA (adica rezonabil) daca insa mut borna si comutatorul pe 10A atata 7.58A adica abereaza saracu`. Sa nu lungesc vorba am ceva cunostinte si scule pt a-l repara dar nu stiu cum si de aceea va cer ajutorul.Multumesc Alex
