Momwe mungadziwire chotenthetsera cha uvuni ndi njira yabwino kapena yoyipa?

Momwe mungayesere chowotcha cha Oven tubular ndi njira yabwino, komanso kugwiritsa ntchito chotenthetsera cha uvuni ndikofala kwambiri pazida zomwe zimafunikira kutentha.Komabe, pamene chubu chotenthetsera chalephera ndipo sichikugwiritsidwa ntchito, tiyenera kuchita chiyani?Kodi tiyenera kuweruza bwanji ngati chubu chotenthetsera ndi chabwino kapena choipa?

1, ndi kukana kwa multimeter kumatha kuyeza kukana, ma ohm angapo mpaka ma ohm angapo ndiabwino, masauzande a ohms komanso apamwamba, ndi oyipa.

2. Malingana ndi mphamvu ya mapangidwe a magetsi ndi chowotcha chubu cha ng'anjo, kukana kwa chubu chotenthetsera kumawerengedwa ngati R = (V x V) / P (R imayimira kukana, V imayimira voteji, P imayimira mphamvu) .Zotsatira zake ndi zabwino ngati zili zazikulu kuposa 0 komanso zosakwana 1000.

3, motero, poyezera ndi fayilo ya ohm (× 10Ω) ya multimeter, ngati kuwerenga kuli kosalekeza kapena pafupi ndi infinity, ndi dera lotseguka.Kuwerenga kumasonyeza bwino, palibe kuwonongeka.

4. Ngati chubu chotenthetsera ng'anjo sichiyatsidwa, onani ngati pali mabowo oonekera, trachoma, kusweka ndi kuphulika pamwamba pa thupi la chubu.Ngati palibe mabowo owonekera, trachoma, kusweka ndi kuphulika, nthawi zambiri zimakhala zabwino.
Njira yoweruzira: Ngati pali mabowo owoneka bwino, trachoma, kusweka ndi kuphulika pamwamba pa chotenthetsera chamoto chosapanga dzimbiri, zikuwonetsa kuti chubu chotenthetsera chawonongeka ndipo sichingagwiritsidwe ntchito moyenera.Pamene mtengo wotsutsa umayesedwa ndi zero, umasonyezanso kuti chubu chotenthetsera sichingagwiritsidwe ntchito;Ngati pamwamba ndi bwino ndipo mtengo wotsutsa uli mkati mwazovomerezeka, ndiye kuti zifukwa zina ziyenera kupezeka.

Ngati mukufuna zinthu zathu, mukhoza kulankhula nafe mwachindunji!
