Multimeter imagwiritsa ntchito zipangizo zomwe zingakhale zothandiza tsiku ndi tsiku. Ndi chithandizo chawo, mungathe kuthetsa mafunso ambiri, mwachitsanzo, momwe mungayese mphamvu ya batri ndi multimeter? Pofuna kugwiritsa ntchito izi mwazizolowezi, muyenera kutsatira ndondomeko yotsatira.
Cholinga cha multimeter
Ndi chithandizo cha tester, simungangowonongeka mphamvu ya mabatire omwe ali ndi multimeter, komanso mowonjezereka mowonjezereka, omwe mungagwiritse ntchito zotsatirazi:
- fufuzani kupuma mu intaneti yamakina;
- kuwona kufunika kwa magetsi muzitsulo;
- kutsimikiza kwa kukanidwa mtengo mu intaneti;
- kuyang'ana momwe magetsi amagwiritsira ntchito, komanso mababu;
- chabwino, ndi ndondomeko zatchulidwa kale, kupereka yankho ku funso, momwe mungayang'anire batri mphamvu ndi multimeter.
Kodi mungayime bwanji?
Kuti mumvetsetse vuto la momwe mungayang'anire mphamvu ya batri ndi multimeter, pakufunika njira zingapo. Choyamba ndichotsegula chipangizo ndikuchiyika pa "DC - Amperes". Pambuyo pake, muyenera kukonza zizindikiro zovomerezeka za madoko:
- Phindu la phukusi la kafukufuku pa nambala 1 liyenera kukhala COM;
- khalidwe la doko la kafukufuku pa nambala 2 liyenera kukhazikitsidwa ku 10ADC;
- Mankhwalawa ayenera kukhala pamalo otchedwa DAC kapena DCA;
- Chotsatira chachikulu cha kutsimikiziridwa sayenera kukhala pansi pa 6 A ndi pamwamba pa 10 A.
Ziyenera kukumbukira kuti kugwiritsa ntchito "Volta" udindo kuti adziwe mphamvu yamakono silololedwa. Tsopano tikuyenera kugwirizanitsa zida za chiyeso kwa oyanjana, malingana ndi achibale otsatirawa:
- Malo "+" amagwirizana ndi "+" pa bateri;
- Choncho, malo osokoneza akugwirizana ndi mbali yolakwika.
Musawope kuti polarity idzasokonezeka. Mu zochitikazi, chizindikiro chotsalira chokha chidzawonekera chiwerengerocho chisanakhalepo. Mukamapanga chiyeso, nkofunika kuti musapitirize-kutsekereza dera lotsekedwa, chifukwa zochitika zoterezi zingapangitse kuwonongeka kwa ngakhale batri yatsopano. Nthawi yayikulu yothandizira nthawi sayenera kupitirira masekondi awiri. Izi ndi zokwanira kuti muone kufunika kwa parameter yamtengo wapatali pachiwonetsero cha tester. Choyenera, chirichonse chiyenera kupatsidwa osachepera mphindi imodzi.
Zotsatira zamatsitsi
Malinga ndi zomwe analandila, n'zotheka kupeza zokhudzana ndi zomwe zidzachitike pogwiritsa ntchito batri. Ndi bwino kukumbukira kokha kuti mtengo wapatali wa parameter woyenera, ndi wamphamvu kwambiri.
- kotero, mwachitsanzo, kutalika kwake kungagwire bwino bwino ndi batri yomwe ili ndi mphamvu yatsopano ya 1A. Koma kuti agwiritse ntchito molondola kamera, chizindikiro choposa 5 A chofunika;
- mphamvu yamakono isanathe kufika 1 A - ingagwiritsidwe ntchito pokhapokha ngati magetsi akugwiritsira ntchito magetsi omwe amawononga mphamvu zopanda mphamvu. Zida zimenezi ndi radiyo yaying'ono kapena mawotchi.
Njira yabwino kwambiri yothetsera thanzi yoyenera ya batri ndikuyiyika mu chipangizo cha magetsi. Pambuyo poyeza chiwerengerochi, sikoyenera kupotoka pazomwe zimasonyezedwa mwachindunji pa betri. Kawirikawiri, silingalembedwe, koma mphamvu zotchulidwa kapena mawu ena. Nthaŵi zambiri, magawo otsatirawa akufotokozedwa:
- 1.5 V - amasonyeza mabatire atsopano a galvanic (disposable);
- 1.2 V - chomwe selo ya betri imapereka.
Potsatira ndondomeko inayake ya zochita, mukhoza kuyeza mphamvu ya batri pogwiritsa ntchito multimeter. Izi zidzakuthandizani kusankha chipangizo chomwe mungagwiritse ntchito.
