Clampmetru masurari uzuale 2021

Recommended Posts

Salut Colegi!

Am citit ceva topicuri pe forum,  sunt daor amator,  si as zice clampetru nu multimetru , pentru siguranta utilizarii sub tensiune (cand am nevoie) si amperaje mai mari de 10A.

Nu am pretentii de la aparat (nu ma deranjeaza deloc o eraore de 2-3% in plus fata de cele superioare)


Ceva la vreo 200 lei as vrea, pt masuratori in casa, auto:
-masor la prizele din casa, continuitate, lipsa nul (am ceva probeleme la mai multe);
-la aparate ,masina de spalat etc ,

-masurare discountuitate cu localizare (fir casti, alimentatoare )
-la auto 12 V;
 

Ma gandesc  clampetru pt ca as putea masura si in timpul functionarii, fara sa tai fire  sertizate ca sa pui sondele pe ele ca in cazul multimetru.



 Am comparat  toata gama UNI T si am gasit cel mia potricit 202F ( aC/ DC, are toate functiile inclusiv masurari frecventa, capacitate etc

Sta bine la intervale de masurare si la Curent si la Tensiune , capacitati maximale

Va recomand si aici ca si dincolo sa cumparati UNI-T 203

....pe langa cele mentionate mai sus ca domenii de masura,are avantajul major ca poate masura la cleste si curentul continuu...

Am cumparat 2 UT213C,unul pentru frate-miu i l-am trimis in Spania imi spusese sa ii cumpar eu un aparat, unul pentru lucru.Pentru un electrician-electromecanic are toate functiile necesare, nu exista un aparat bun la toate, dar cu asta poti sa urmaresti cu aproximatie si traseele de cabluri prin pereti, masoara si temperatura, pot sa zic ca este un aparat foarte bun la pretul lui.

Eu  as lua UT 202f LA jumatate din pret UT203+, SI LA SPEC AM VAZUT CA MASOARA SI VOLTAJUL DC

 

 la curent continuu as avea acumulatori ,auto de verificat ,   vad ca duce 600V si asta , adica eu alteva nu prea masor la DC (eventual acc Litiu)

Aveti dreptate, am vazut.  Dar cu un Clampmetru fara verficiare Curent pe DC ,nu stiu daca  e acum problema.  As verfica in general de ex la masina de spalat compenenete arse, la prize defectiuni, eventual testez sa vad circuitele pana la sigurantele automate, rezistori, continuitate, fuzibile etc.

 

Clampul il folosesc si cu buzzer pt a nu  intrerupe circuitul , daca am curent pe un circuit inseamna ca am si tensiune , stiu ca mai apar interferente, cand in jur e curent pe alte fire , dar in general nu stiu daca anuleaza complet citirea continuitatii.(depinde ce plaje de interferente suporta bobina)

 

Daca e musai , il iau pe cel cu 203, ma gandeam ca o sa mi iau de pe Bangood un Multmetru cu Osciloscop eventual si acolo oricum o sa am functii (asta daca o sa ma nevoie pt ca o sa fac studii in fac. electrica).
