Momwe mungagwiritsire ntchito Cen Tech multimeter? (7 Zitsogozo)

18.02.2023 /

M'nkhaniyi, ndikuphunzitsani momwe mungagwiritsire ntchito ntchito zonse zisanu ndi ziwiri za Centech DMM.

Cen Tech multimeter ndi yosiyana pang'ono ndi ma multimeter ena a digito. 98025 yokhala ndi ntchito zisanu ndi ziwiri imatha kugwira ntchito zosiyanasiyana. Ndagwiritsa ntchito izi m'mapulojekiti anga ambiri amagetsi ndipo ndikuyembekeza kukuphunzitsani zonse zomwe ndikudziwa.

Nthawi zambiri, kugwiritsa ntchito Cen Tech multimeter:

  • Lumikizani blackjack ku doko la COM.
  • Lumikizani cholumikizira chofiira ku doko la VΩmA kapena 10ADC.
  • Yatsani mphamvu.
  • Sinthani kuyimba ku chizindikiro choyenera.
  • Sinthani tcheru.
  • Lumikizani mawaya akuda ndi ofiira ku mawaya ozungulira.
  • Lembani kuwerenga.

Werengani kalozera pansipa kuti muphunzire za zinthu zisanu ndi ziwiri za Cen Tech DMM.

Upangiri Wathunthu Wogwiritsa Ntchito Cen Tech Multimeter

Muyenera kudziwa zina za ntchito zisanu ndi ziwirizi

Kumvetsetsa ntchito za Cen Tech multimeter kudzakhala kothandiza mukamagwiritsa ntchito. Chifukwa chake nazi zinthu zisanu ndi ziwiri za CenTech DMM.

  1. Kutsutsana
  2. Voteji
  3. Pakali pano mpaka 200 mA
  4. Pakali pano pamwamba pa 200mA
  5. Kuyeza kwa diode
  6. Kuyang'ana mkhalidwe wa transistor
  7. Mphamvu ya batri

Pambuyo pake ndikuphunzitsani momwe mungagwiritsire ntchito ntchito zisanu ndi ziwiri zonse. Pakalipano, apa pali zizindikiro zofanana za ntchito zonse.

  1. Ω amatanthauza ma ohms ndipo mutha kugwiritsa ntchito izi kuyesa kukana.
  2. DCV imayimira DC voltage. 
  3. sitiroko imayimira AC voltage.
  4. DCA imayimira Direct current.
  5. Makona atatu okhala ndi mzere woyima kumanja ndikuyesa ma diode.
  6. hFE amagwiritsidwa ntchito kuyesa ma transistors.
  7. Mizere iwiri yoyimirira yokhala ndi mzere wopingasa ndi yoyesa batire.

Zizindikiro zonsezi zitha kupezeka m'dera la multimeter. Chifukwa chake, ngati ndinu atsopano kumitundu ya Cen Tech, onetsetsani kuti mwayang'ana musanayambe.

Madoko ndi zikhomo

Cen Tech multimeter imabwera ndi zitsogozo ziwiri; wakuda ndi wofiira. Mawaya ena akhoza kukhala ndi timapepala ta ng'ona. Ndipo ena sangatero.

Waya wakuda amalumikizana ndi doko la multimeter's COM. Ndipo waya wofiyira amalumikizana ndi doko la VΩmA kapena doko la 10ADC.

Chidule mwamsanga: Mukayeza pano pansi pa 200 mA, gwiritsani ntchito doko la VΩmA. Pamafunde opitilira 200mA, gwiritsani ntchito doko la 10ADC.

Kugwiritsa ntchito ntchito zonse zisanu ndi ziwiri za Cen Tech multimeter

Mugawoli, muphunzira momwe mungagwiritsire ntchito ntchito zisanu ndi ziwiri za Cen Tech multimeter. Apa mutha kuphunzira kuchokera pakuyezera kukana mpaka kuyang'ana kuchuluka kwa batri.

Yesani kukana

  1. Lumikizani blackjack ku doko la COM.
  2. Lumikizani cholumikizira chofiyira ku doko la VΩmA.
  3. Yatsani multimeter.
  4. Sinthani kuyimba kukhala chizindikiro cha 200 m'dera la Ω (Ohm).
  5. Gwirani mawaya awiri ndikuwunika kukana (kuyenera kukhala ziro).
  6. Lumikizani mawaya ofiira ndi akuda ku mawaya ozungulira.
  7. Lembani kukana.

Chidule mwamsanga: Ngati mupeza chimodzi mwazowerengera, sinthani kuchuluka kwa chidwi. Mwachitsanzo, tembenuzani kuyimba kwa 2000.

Mukhozanso kuyang'ana kupitiriza pogwiritsa ntchito zokonda zotsutsa. Sinthani kuyimba kukhala 2000K ndikuyang'ana dera. Ngati kuwerenga ndi 1, dera limatsegulidwa; ngati kuwerenga ndi 0, ndi dera lotsekedwa.

Kuyeza kwa magetsi

DC voltage

  1. Lumikizani blackjack ku doko la COM.
  2. Lumikizani cholumikizira chofiyira ku doko la VΩmA.
  3. Yatsani multimeter.
  4. Sinthani kuyimba kukhala 1000 mdera la DCV.
  5. Lumikizani mawaya ku mawaya ozungulira.
  6. Ngati kuwerengako sikuchepera 200, tembenuzirani kuyimba kwa 200.
  7. Ngati kuwerengako sikuchepera 20, tembenuzirani kuyimba kwa 20.
  8. Pitirizani kuzungulira kuyimba ngati pakufunika.

Mphamvu ya AC

  1. Lumikizani blackjack ku doko la COM.
  2. Lumikizani cholumikizira chofiyira ku doko la VΩmA.

Pankhani ya transistors, pali mitundu iwiri; NNP ndi PNP. Choncho, musanayese, muyenera kudziwa mtundu wa transistor.

Kuphatikiza apo, ma terminals atatu a transistor amadziwika kuti emitter, base, ndi otolera. Pini yapakati ndiye maziko. Pini kumanja (kumanja kwanu) ndi emitter. Ndipo pini yakumanzere ndi yosonkhanitsa.

Nthawi zonse zindikirani mtundu wa transistor ndi mapini atatu molondola musanalumikize transistor ku Cen Tech multimeter. Kugwiritsa ntchito molakwika kumatha kuwononga transistor kapena multimeter.

Kuyeza kwa batri (kuyezetsa mphamvu ya batri)

  1. Sinthani kuyimba kumalo oyesera batire (pafupi ndi dera la ACV).
  2. Lumikizani blackjack ku doko la COM.
  3. Lumikizani cholumikizira chofiyira ku doko la VΩmA.
  4. Yatsani multimeter.
  5. Lumikizani waya wofiyira ku batire yokwanira.
  6. Lumikizani waya wakuda ku terminal yopanda pake.
  7. Fananizani kuwerenga ndi mphamvu ya batire yamwadzina.

Ndi Cen Tech Multimeter, mutha kuyesa mabatire a 9V, C-cell, D-cell, AAA ndi AA. Komabe, musayese mabatire agalimoto a 6V kapena 12V. Gwiritsani ntchito voltmeter m'malo mwake.

zofunika: Nkhani yomwe ili pamwambayi ikukhudza ntchito zisanu ndi ziwiri za Cen Tech 98025. Komabe, chitsanzo cha 95683 ndi chosiyana pang'ono ndi chitsanzo cha 98025. Mwachitsanzo, mudzapeza doko la 10A m'malo mwa doko la 10ADC. Kuphatikiza apo, mutha kupeza zone ya ACA ya AC. Musaiwale kuwerenga buku la Centtech DMM ngati mwasokonezeka pa izi. 

Onani zina mwazolemba zathu pansipa.

  • Cen Tech 7 ntchito DMM kuwunika
  • Chizindikiro cha multimeter diode
  • Tebulo la chizindikiro cha Multimeter
