Multimetru UNI-T UT30C

Recommended Posts

Acest aparat ''merge bine, dar e putin defect''.

Masoara tot ce vrei, in afara de continuitate/diode.

Pe acest domeniu (continuitate) afisajul se joaca rapid de la cca700 ohmi la 30-40. Niciodata nu ajunge la zero. Buzzer-ul ar da un semn cand se ajunge la valoare mica, un timp foarte scurt.

La masurare diode/ tranzistor, se comporta la fel. O jonctiune care ar trebui sa o arate de cca 600 ohmi, afisajul se joaca de la opt sute si ceva, revine, trece peste 1000, in fractiuni de secunda.

In domeniul CC masoara corect, CA corect, curent CC corect.

Cine e ''responabil'' cu citirea continuitate/jonctiuni?

Cablurile de masura sunt bune.

Nu e aparatul meu, deci nu sunt interesat de masurari ''electronice''.

Asa e, si pe domeniul rezistente masoara tot aiurea.  Deci, pana isi cumpara alt aparat, se poate remedia cumva?

O fi inauntru un pinguin la tabla , si a ramas repetent la fizica? (ca sa mai si glumim)

nu, cam la fel se poartă şi multimetrele mele de la o vreme, şi nu poţi repara nimic fără un aparat de măsură sigur "fără pitici"...
