Kodi mamilimita 50 amawoneka bwanji pa multimeter? Anafotokoza

Multimeter imawonetsa 50 milliamp ngati 0.05 amps pazenera. Ukafunsa bwanji? Khalani nafe chifukwa, mu positi iyi yabulogu, tiyang'ana mwatsatanetsatane momwe 50 milliamp imawoneka pa multimeter!

Kodi multimeter ndi chiyani ndipo imachita chiyani?

Multimeter ndi chipangizo chomwe chimayesa zinthu zosiyanasiyana zamagetsi, kuphatikiza ma voltage, apano komanso kukana. Itha kugwiritsidwa ntchito kuyesa mabatire, ma wiring ndi zida zina zamagetsi.

Multimeters nthawi zambiri amakhala ndi miyeso yambiri yamagetsi komanso yapano, komanso miyeso ingapo yokana. Angagwiritsidwenso ntchito kuyesa ma capacitors ndi ma diode.

Multimeter ndi chida chofunikira pamagetsi. Ikhoza kukuthandizani kudziwa chomwe chiri cholakwika ndi chipangizo ngati sichikugwira ntchito kapena kugwiritsa ntchito ngati gawo la benchi yanu yomwe mumagwiritsa ntchito zida zosiyanasiyana zamagetsi.

Mwachidule, ma multimeter amayesa ma voltage, apano komanso kukana. Itha kugwiritsidwa ntchito kuyesa mabatire, fuse, mawaya, ndi zida zina zamagetsi. Masiku ano amagwiritsa ntchito zowonetsera za digito zomwe zimapangitsa kuti zikhale zosavuta kuwerenga miyeso.

Ma Multimeters amagwiritsa ntchito zowonetsera za digito zomwe zimawapangitsa kukhala osavuta kugwiritsa ntchito ndikukupatsani miyeso yolondola, posatengera zomwe zilipo. Ma multimeter amakono adapangidwanso kuti akhale a ergonomic komanso opepuka kotero kuti ndi osavuta kugwiritsa ntchito ngakhale mutawagwiritsa ntchito kwa maola ambiri.

Kodi mamilimita 50 amawoneka bwanji pa multimeter?

Mukamayesa zamakono ndi ma multimeter, kuwerenga kudzakhala ma amps. 50 milliamp ndi ofanana ndi 0.05 amps. Izi zikutanthauza kuti pa ma multimeter ambiri, kuwerenga kwa mamilimita 50 kudzawonetsedwa ngati kadontho kakang'ono kapena mzere pazenera.

Poyezera mafunde ndi ma multimeter, sikelo pa mita idzakhala mu amps. Milliamp ndi kachigawo kakang'ono ka amp, kotero poyezera mafunde omwe ali 10 milliamp kapena kutsika, mita idzawonetsa mtengo wa 0.01 pa amp scale. Izi ndichifukwa choti mita imayesa kuchuluka kwa ma amps.

Poyesa mafunde ndi multimeter, ndikofunika kuzindikira kuti mita idzangoyerekeza ndi kuchuluka kwa panopa.

Kuchuluka kwamakono komwe kungayesedwe ndi ma multimeter ambiri ndi kuzungulira 10 amps. Ngati mukuyesa zamakono zomwe zili pamwamba kuposa 10 amps, mita idzawonetsa mtengo wa 10 pa amp sikelo.

Kumvetsetsa amperes, milliamps ndi ma microamp

An ampere (A) ndi gawo loyambira la SI lamagetsi apano. Ndi kuchuluka kwa zomwe zikuyenda kudzera pa conductor pamene voteji ya 1 volt ikugwiritsidwa ntchito. Milliamp (mA) ndi gawo limodzi mwa magawo XNUMX a ampere, ndipo microamp (μA) ndi gawo limodzi la miliyoni la ampere.

Mayendedwe apano amayezedwa mu ma ampere. Milliamp ndi yaying'ono yapano, ndipo microamp ndi yaying'ono kwambiri yapano.

Mayendedwe apano muderali akhoza kukhala oopsa ngati sikunangokhala pamlingo wotetezeka. Ndikofunikira kumvetsetsa kusiyana pakati pa ma ampere, ma milliamp ndi ma microamp mukamagwira ntchito ndi ma circuit amagetsi.

Table ya ampere unit

Dzina loyamba komanso lomaliza	Chizindikiro	Kutembenuka	Chitsanzo:
microamp (microamp)	μA	1 μA = 10-6A	I = 50μA
milliampere	mA	1 mA = 10-3A	I = 3 mA
ampere (amps)	A	-	I = 10 A
kiloampere (kiloampere)	kA	1kA = 103A	I = 2kA

Momwe mungasinthire ma amps kukhala ma microamp (μA)

I yapano mu microamperes (μA) ndi yofanana ndi I yapano mu amperes (A) yogawidwa ndi 1000000:

I_(μA) = I_(A) / 1000000

Momwe mungasinthire ma amps kukhala ma milliamp (mA)

Panopa I mu milliamperes (mA) ndi yofanana ndi I yapano mu amperes (A) yogawidwa ndi 1000:

I_(MA) = I_(A) / 1000

Momwe mungagwiritsire ntchito multimeter kuyeza zamakono?

1. Lumikizani multimeter ndikuyatsa

2. Gwirani chowongolera chakuda cha multimeter kupita ku doko la COM (nthawi zambiri doko lozungulira pansi)

3. Gwirani chowongolera chofiyira cholowera padoko la VΩmA (nthawi zambiri doko lapamwamba)

4. Sankhani muyeso waposachedwa potembenuza kuyimba pa multimeter mpaka igwirizane ndi chizindikiro cha muyeso wamakono (uwu udzakhala mzere wa squiggly)

5. Yatsani chipangizo chilichonse chomwe mukuchiyesa polipiritsa chosinthira chake kapena kuchilumikiza

6. Yezerani mphamvu yapano poyika chiwongolero chakuda cha multimeter pa imodzi mwazitsulo zachitsulo ndikukhudza chiwongolero chofiyira cha multimeter kupita ku chitsulo china.

Multimeters ndi zida zabwino zothandizira kuonetsetsa kuti dera lanu likugwira ntchito moyenera. M'nkhaniyi, tiwona momwe mungagwiritsire ntchito multimeter kuyeza zomwe zikuchitika mudera.

Mutha kuwonanso vidiyo yathu yophunzirira momwe mungagwiritsire ntchito multimeter:

Momwe mungagwiritsire ntchito multimeter - (Ultimate Guide For 2022)

Malangizo ogwiritsira ntchito multimeter mosamala

- Nthawi zonse onetsetsani kuti zowongolera za mita zimalumikizidwa bwino ndi ma terminals musanawerenge. Izi zidzathandiza kupewa kuwerengera molakwika komanso kupewa kugwedezeka kwamagetsi.

- Osakhudza ma probe a mita pomwe yalumikizidwa. Izi zitha kuyambitsanso kugunda kwamagetsi.

- Ngati mukuyezera pakalipano mumayendedwe amoyo, onetsetsani kuti mwasamala ndikuwonetsetsa kuti mwavala magalasi oteteza chitetezo ndi magolovesi. Kugwira ntchito ndi magetsi kungakhale koopsa, choncho nthawi zonse muzisamala mukamagwira ntchito ndi zamagetsi.

- Nthawi zonse masulani zida musanaziyese ndi multimeter

- Samalani kuti musakhudze zitsulo zazitsulo za mita ndi manja anu, chifukwa izi zingayambitse magetsi

- Osadzaza mabwalo mukamayesa ndi ma multimeter

- Sungani ana ndi ziweto kutali ndi malo omwe mukugwira ntchito zamagetsi

Zolakwitsa zomwe anthu amachita akamagwiritsa ntchito multimeter

Anthu nthawi zambiri amalakwitsa zodziwika pogwiritsa ntchito multimeter. Zina mwa zolakwikazi ndi monga kusawerenga mndandanda, kusayang'ana fuse, komanso kusazimitsa mphamvu.

1. Kusawerenga mtundu: Nthawi zambiri anthu samawerenga kuchuluka kwa mita, zomwe zingapangitse kuti ayesedwe molakwika. Onetsetsani kuti mwawerenga mndandanda musanatenge miyeso iliyonse.

2. Kusayang'ana fuse: Kulakwitsa kwina kofala ndikusayang'ana fuse pa mita. Fuseyo ikawomberedwa, simungathe kuyeza zolondola.

3. Kusazimitsa magetsi: Kulakwitsa kwina komwe anthu amapanga ndikusayatsa magetsi asanayese. Izi zitha kukhala zowopsa komanso zimatha kuwononga mita.

Pomaliza

Multimeter ndi chida chofunikira kwa aliyense amene amagwira ntchito ndi magetsi. Ngati mumvetsetsa miyeso yosiyanasiyana komanso momwe mungagwiritsire ntchito multimeter mosamala, mutha kuwonetsetsa kuti mapulojekiti anu azikhalabe bwino. Tikukhulupirira kuti tsopano mukumvetsa zomwe 50 milliamp imawoneka pa multimeter ndi momwe mungawerengere.
