Phunzirani kugwiritsa ntchito Tester ndi

Mwatsoka, anthu ambiri kuiwala kuti maphunziro zamagetsi kuphunzira zaka zingapo. Iwo kuphunzira zimene kugwiritsa ntchito Tester, komanso malamulo chitetezo. Komabe, khama yoyenera ndizosowa akhoza katswiri aliyense. Natenepa lero tidzakambirana mmene tingagwiritsire ntchito multimeter.

Choyamba, tiyenera kudziwa zimene zida ngati lingafunikire kunyumba. Eni fulorosenti nyali (mtengo - izi ndi mtundu awo), mwina mwaona kuti nthawi zina usiku ndi nyale yaitali m'gulu, mpaka kulephera kuyamba. Mukhoza, ndithudi, tsiku lotsatira kugula latsopano, koma ngati izi vutolo? Ndipotu, nthawi zambiri yosiyana - mu yafupika magetsi voteji. Pankhaniyi, muyenera kulemba ntchito kwa pempho utumiki koyenera kufufuza nkhaniyo. Mwa njira, nyali - ndi zabwinobwino kwambiri. The voteji dontho akhoza tsekani kompyuta kuthamanga ndi imfa ya zonse zotsatira. Kudziwa voteji multimeter thandizo.

Masitolo katundu magetsi angapezeke mitundu iwiri ya zida chilengedwe - Tester ndi multimeter. Otsiriza, monga dzina lake likunenera, amalola kuchita miyezo ya magawo osiyanasiyana. Ndipo apa Tester pa nyumba chakale diodes angapo, kusonyeza voteji mpandawo, nyali komanso kudziwa gawo wochititsa dera kukhulupirika Alamu (Mayeso) ndi nkhani. Pano pali iye, Tester ntchito tikambirana zina. Komabe, zoona, tiona multimeter lapansi. Onse chifukwa anthu amadziwa pang'ono zomangamanga magetsi, nthawi zambiri kusokoneza zipangizo awiri, Tester akwanitse multimeter.

Kotero, momwe ntchito Tester ndi? Choyamba muyenera kuonetsetsa kuti chipangizo chamagetsi waikidwa undischarged batire. Apo ayi, chifukwa muyeso adzakhala olakwika. Childs, probes awiri, ndi mabowo atatu kulumikiza iwo. kafukufuku wina nthawi zonse olumikizidwa kwa doko Com. Lachiwiri ambiri miyezo ena - kukana, voteji, panopa, mu milliamps. Koma wachitatu okha muyeso wa lalikulu panopa ndi ntchito kokha pamene mode awa anasankhidwa ndi kuponya mavoti a. Amene sadziwa ntchito Tester ayenera powerenga kalembedwe pafupi malo - izo zikunena zonse.

Probes ali anaikapo molondola. Zotsatirazi zina. Tsopano muyenera kusinthana unit (adzaponye chisanko) kuvumbula mode ankafuna. Mwambo womaliza maphunziro awa: DCV dera akutumikira kuyeza DC voteji (mu mabatire izi banja migolo); ACV - chifukwa alternating voteji (mains); DCA - ndi zonse panopa; kukana - kuyeza e. kukana. Pamaso pa magawo ena malingana ndi chitsanzo.

malamulo angapo: chifukwa probes voteji chikugwirizana kufanana kwa katundu, panopa - ndi wochititsa yopuma, komanso mwachindunji amaona impedance (ngati izo siziri mu unyolo).

Mwachitsanzo, muyenera kuonanso ubwino mabatire voteji penlight. Ake voteji mwadzina amadziwika (1.5), kotero ife kusankha yapafupi amenewa, DCV 20 kukhudza probes kuti ojambula ake. Chionetsero kukuwonetsani zotsatira. Ngati mtengo mwadzina Sizikudziwika kungoika malire pazipita kuchepetsa ngati n'koyenera.

Kufufuza voteji mu maukonde nyumba, akonzedwa selector 750 ACV (kuposa 200) mosamala kumanga ndi probes mu kubwereketsa ndi kuona zotsatira.

Panopa chimaonekera mosiyana, mwachitsanzo, kuona phindu lake ankadya tochi kungakhale chipangizo chimodzi polumikiza kafukufuku zolankhulirana batire wina, ndipo chachiwiri - kuti zosiyana tochi osachiritsika. Oponya mavoti anapereka kufunika pazipita (mwachitsanzo, 200 MA, koma osati 10 A, umene lachitatu kafukufuku osachiritsika).

Fundo chimaonekera ndithu chabe - pa wagawo ndi kuika mtengo wapatali, kenako amachepetsa.

Mfundo momwe ntchito Tester, pali kanthu kovuta. Pamene ntchito unit chachikulu - osati kusakaniza kuchuluka anayeza ndi kusamala kwambiri.
