Ndi multimeter iti yomwe ndiyenera kusankha pa galimoto? Mwachidule, mitundu, mitengo

Kugwiritsidwa ntchito kwa galimoto kaŵirikaŵiri kumagwirizanitsidwa ndi kugwira ntchito zamagetsi, ngakhale ngati zikukhudza zolephera zazikulu. Zipangizo zamagetsi zimadalira kwambiri, choncho kukonza njirayi kumaperekedwa kwa akatswiri. Koma palinso njira zosavuta, zomwe nthawi zambiri zimathandiza kuti ngakhale munthu wopanda magalimoto azidziwa zambiri. Mwachitsanzo, zikhoza kuyang'ana magetsi pamphepetezo kapena kuyesa kutsutsana kwamakono pa webusaiti. Pakuti machitidwe oterowo ayesedwa - multimeters. Ichi ndi chipangizo chochepa chomwe chimakulolani kuti muchite miyeso yofunikira mu mphindi. Ndi multimeter iti yomwe mungasankhe ndi funso losavuta, ndipo yankho lake lingaperekedwe pokhapokha mutaganizira zosowa za munthu payekha. Komabe, pali malamulo ambiri a chisankho ichi, chidziwitso chomwe chingathandize kuthetsa vutoli.

Zambiri zokhudza ma multimeters

Chipangizocho ndi chida choyezera, chomwe chimalola kugwiritsa ntchito ntchito yake kuyesa dera la magetsi, komanso kusonyeza makhalidwe ake enieni. M'mawonekedwe ofanana, zipangizo zoterezi zimagwira ntchito za voltmeters, ohmmeters ndi ammeters. Zitha kunenedwa, izi ndizo ntchito, yomwe imadziwika ndi multimeter. Kodi ndi bwino kusankha nyumba? Mwinamwake, ponena za kugwira bwino ntchitoyi ntchitoyi ndi yokwanira zofunikira zapakhomo.

Komabe, chifukwa cha galimotoyo ndizomwe mungapereke zowonjezera. Makamaka, zitsanzo zamtundu umenewu zimaperekanso kugwira ntchito ndi zipangizo zina. Zida zoterezi zimakulolani kudziwa zizindikiro za tachometer ndi mpikisano wamagetsi. Zoonadi, kulembetsa ntchito nthawi zambiri sikumaphatikizapo kulemera kwa chiyeso. Choncho, m'pofunika kumamatira kusintha kosinthika kumene multimeter yamakono ikupangidwa. Ndibwino kuti musankhe mwachinsinsi chogwiritsa ntchito - komanso nkhani yofunikira, yomwe imaganizira za maonekedwe oyenera. Makamaka, mwayi wogwiritsa ntchito chipangizocho udzadalira mtundu wake.

Zosiyanasiyana za chipangizochi

Kulekanitsa kwapadera kumachitika ndi njira yoyendetsera ndi kufotokoza deta yolingalira. Makhalidwe obsolete, koma odalirika analog zipangizo ndi mawotchi kulamulira zinthu akadali mukufunika pa msika. Izi ndi magetsi omwe amasiyana ndi osagwira ntchito, koma nthawi yomweyo amamvetsetsa kwa ambiri omwe amagwiritsa ntchito makasitomala. Koma kuti m'malo mwa oyesedwa akale amachokera multimeter multimeter. Ndibwino kuti musankhe galimoto ngati choncho? Ndi zofunika kuganizira zitsanzo ndi nkhupakupa. Zosintha zoterezi, makamaka, zimayenera kwambiri kugwira ntchito ndi batri phukusi, chifukwa sichikusowa zofunikira zina. Pokhapokha, mawonekedwe a digito ya multimeter ndi opindulitsa pa njira yamakono yoperekera deta yomwe imachokera kuwonetseredwe kowonekera. M'masinthidwe omasulidwa, makina opanga makompyuta amagwiritsidwanso ntchito, chifukwa choti n'zotheka kupanga ndi kukonza deta yolandila.

Zosankha zoyenera

Zigawo zamakono ziyenera kukhala maziko a kusankha. Izi zikugwiritsidwa ntchito kuzinthu zamtengo wapatali. Makamaka, pogwiritsa ntchito multimeter yosiyanasiyana, wogwiritsa ntchito akhoza kudziwa mphamvu yamakono kuyambira pa 0.1 μA mpaka 10 A. Kutsimikiziridwa, komwe kumaperekedwa ndi multimeter, kumathandizidwanso - kodi ndiji yabwino kwambiri pa chizindikiro ichi? Zoonadi, apamwamba kwambiri, amakhala abwino kwambiri. Izi zimathandiza kuti mudziwe zambiri za miyesoyi. Chinthu chinanso ndikuti kusunga bwino sikoyenera nthawi zonse.

Chofunikira chofunikira cha kusankha ndiko kulondola kwa chipangizo. Mwachivomerezo, akuyimiridwa ngati chinthu cholakwika. Mwachitsanzo, kwa oyesa digito, mtengo umenewu nthawi zambiri umakhala wochokera ku 0.02 mpaka 3%. Koma mu funso la momwe mungasankhire multimeter mulingo, chidziwitso chenichenicho ndi chofunikira, popeza zipangizo zochepa zowonjezera nthawi zambiri zimayang'aniridwa. Ndipo ponena za kukhazikika kwa miyeso, mwa njira, nthawi zina kusinthika kofanana kumaposa iwo okha.

Model FLUKE 15B

Chipangizo chogwiritsira ntchito chofunikira pa chilengedwe chonse, chimene ntchitoyi imasintha mu kayendedwe ka galimoto. Mtengo ndi woimira mwachidule gawo la oyesa digito. Zimasiyanitsa ndi mlingo wochepa wolakwika wa 0,5%, komanso kukhalapo kwa njira zowunikira ndikuwongolera. Mwachitsanzo, ngati pali funso lomwe multimeter liyenera kusankhidwa kuchokera pa malo owonera bwino kwambiri, ndiye kuti tikhoza kusankha moyenera chipangizo ichi. Zomwe zimagwiritsa ntchito zimalola popanda kugwiritsa ntchito njira kuti muzindikire zoyenera kwambiri. Ndipo pambuyo poyeza, chipangizochi chidzapereka zizindikiro zomveka. Mwa njira, deta ikusinthidwa ma sekondi atatu, zomwe zimapangitsa kuti msangamsanga kukhazikitsidwa kwa miyeso yovuta.

Chitsanzo Mastech MS8040

Woimira gulu losawerengeka la oyesa mafakitale amene samakumana nawo tsiku ndi tsiku m'moyo, koma nthawi zina zitsanzo zoterezi zimadziyimira okha mu chuma cha anthu oyendetsa galimoto. Makamaka ngati, kuwonjezera pa kusunga betri, wogwiritsa ntchitoyo akugwira ntchito yamagetsi. Manambala apamwamba, mwayi wogwira ntchito ndi unyolo wa chile, kulingalira kwa maulendo ofanana ndi matalikidwe ake ndi gawo limodzi la ubwino umene multimeter iyi imakhala nayo. Kodi ndi bwino kusankha positi kuchokera ku gawo la zipangizo zamaluso? Funso limeneli likufunsidwa ndi oyendetsa magalimoto amene, kuphatikizapo zizindikiro zazikulu, akukonzeketsanso kulemba mphamvu ya dera, nthawi ndi kutentha. Ndipo kusinthidwa kwa MS8040 kuli koyenera pa zosowa zimenezo. Pa chifukwa chimenechi, ogwira ntchito galimoto ambiri amagwiritsa ntchito chitsanzo, ngakhale kuti, kusowa kuyenda ndizovuta kwambiri.

Chitsanzo CEM DT-101

Ngati njira yosavuta ikufunika kuti muchite zochitika zosawerengeka m'ndandanda wa zizindikiro, njirayi ingakhale yoyenera. Mu gawo la bajeti, iye ndi amenenso ali wodalirika kwambiri, ngakhale kuti ali ochepa mu luso lake. Ubwino wa chipangizocho umaphatikizapo kugwirizana, kumasuka komanso kuphweka. Mu yankho la funso limene multimeter ndi yabwino kusankha posankha mofulumira komanso mopanda phindu la magawo a dera, chitsanzo ichi chikhoza kulingalira bwinobwino. Kuwonjezera pamenepo, woyeserera muyiyiyi ali ndi mawonekedwe a digito ndi machitidwe opangidwa bwino, kotero kuti woyambira, zingakhale bwino.

Kodi multimeter amawononga ndalama zingati?

Mtundu wapamwambawu umagula ma ruble 700. Mu gawo mpaka 1000 rubles. Palinso zopereka zambiri zosangalatsa ndi mwayi wambiri. Ambiri mwa kalasi amapereka zipangizo ndi malonda a mtengo wa dongosolo la 1.5-2 zikwi ruble. Ichi ndi chida chokhala ndi zipangizo zambiri zomwe zili ndizinthu zodalirika komanso zamakono. Kupatula gawo lomwelo, pali muluso wamakono. Ndibwino kuti musankhe? Mtengo, womwe ulipo pafupi ndi zikwi makumi awiri, ukhoza kusokoneza zosankhazo, kapena kuti, zingapangitse kuti ziwoneke bwino kwambiri kuti adziwe momwe ntchitoyo ikufunira. Kutumikira kumudzi kwa galimoto kungatheke kukhala kokha kumagetsi otsika mtengo. Koma, monga taonera kale, ngati mukufuna kugwiritsa ntchito chipangizo china, ntchito yowonjezera yowonjezera komanso yowonjezera nthawi, zimakhala zomveka kuti mupeze njira yapamwamba monga MS8040 kuchokera ku Mastech.

Kutsiliza

Mu multimeters, mosasamala kanthu kuti iwo amakhala a kalasi inayake, magawo osalunjika nthawi zambiri sali ofunika kwambiri. Izi zikugwiritsidwa ntchito, makamaka, njira ya zakudya. Ndi multimeter yotani yomwe mungasankhe mwayi? Batireyo iyenera kukhala yodalirika komanso yodalirika, kuti musalole kuti mukhale pansi pa kusintha kwa kutentha. Bwino la betri ndi lovuta kuunika pakasankhidwa, koma opanga chipangizo cha FLUKE kapena Mastech sagwiritsa ntchito mankhwala awo moyenera komanso opanda mphamvu.
