Kodi kusankha multimeter nyumba ndi galimoto

Mpaka zaka zingapo zapitazo, mbuye, amene anali kugwira ntchito ndi magetsi, akhoza kukhala popanda zipangizo ngati zothandiza monga ohmmeter, voltmeter ndi ammeter. Lero iwo anabwera m'malo mita. Yotsirizira ndi chipangizo chilengedwe zoti ziyesedwe zosiyanasiyana magawo magetsi ndi Intaneti. Tiyeni tione mmene kusankha multimeter nyumba ndi galimoto, kuganizira cholinga cha gulu zipangizo, magwiridwe awo.

anayeza multimeter ndi chiyani?

akhoza kuyesedwa ntchito chipangizo izi:

• DC ndi AC voteji;
• capacitance;
• kutentha mu madera osiyana a dera magetsi;
• transistors ntchito ndi diodes;
• inductance coils;
• DC ndi AC panopa.

mitundu multimeters

Pamaso lodziwa mmene kusankha multimeter wabwino, muyenera kuganizira mitundu ya zipangizo zimenezi. Panopa alipo ambuye makompyuta ndi zipangizo analogi. Taganizirani mbali zawo.

Mu zipangizo analogi miyezo onse amalembedwa bala likutipatsa kupita muvi ndi ulemu magawano. Lili ndi calibration, aliyense wa Chofanana chizindikiro makamaka. The drawback waukulu wa mfundo imeneyi - ndi inaccuracy wachibale wa umboni. Ngakhale Mkhalidwe analogi multimeter muvi pang'ono fluctuates mbali, imbaenda deta ena kupotozedwa. Mwachibadwa, ngati mbuye ayenera kukonza mfundo zofanana yekha, ndi chipangizo chimenechi woyenera izo. Ambiri, analogi zipangizo pafupifupi chakale, kotero ntchito lero n'zochepa kwambiri.

Ndikudabwa za mmene kusankha multimeter, amisiri odziwa kulabadira makamaka zipangizo zamagetsi. deta onse ndi kwaiye pa kuwonetsera yadigito. kuwerenga repeatable ndi zolondola ndi zovuta kumvetsa. Pakompyuta zipangizo mu mbali kwambiri zaphindu magwiridwe lonse.

Pa mfundo zimene muyenera kulabadira pamene pogula multimeter?

Pali zingapo liwulo mikhalidwe imene tiyenela kuiganizila posankha chipangizo choyezera :

• osiyanasiyana zizindikiro;
• zolakwa;
• pang'ono miyezo;
• amagetsi chipangizo;
• chiwerengero cha kusonyezedwa.

Yotsatirayi, ganizirani mmene kusankha multimeter poganizira magawo awa.

Osiyanasiyana zizindikiro

Mbali mankhwala zikusonyeza pazipita ndi osachepera malire mfundo za magawo omwe ayenera kuti idzitha kuyezeka. Kusankha multimeter, kuyambira osiyanasiyana zizindikiro, malingana ndi kuchuluka anafuna chipangizo. Ngati mukufuna ntchito ntchito mu zikhalidwe za moyo, mu nkhani iyi zokwanira kusiya kusankha pa chipangizo ndi osiyanasiyana yaing'ono. Monga ntchito mafakitale, pali bwino amakonda multimeter ndi zotheka osiyanasiyana linafalitsidwa kwambiri lililonse chizindikiro chofunika.

zolakwa

Ngakhale apamwamba zipangizo zambiri zamagetsi musalole kuti miyezo yeniyeni mwamtheradi. Nthawi zonse ali ndi zolakwa zazing'ono, zomwe zipangizo osiyana siyana mu osiyanasiyana kuchokera 0,02 kuti 3%. Kudziwa momwe kusankha Tester-multimeter, tiyenela kuika ndithu kuti kupatuka alipo.

Ngati chipangizo choyezera ndi Anagula kutsatira zamagetsi ntchito, izo tikulimbikitsidwa kulabadira zitsanzo ndi cholakwika chaching'ono kwambiri. Pamene ntchito ya zoweta Tester, padzakhala woyenera chipangizo ndi ena kupatuka pa magawo enieni ntchito.

mphamvu

Akamanena za chizindikiro n'lakuti, Kodi kuwerenga molondola akhoza chinaonekeranso mafilimu kuyeza chipangizo. Mwachitsanzo, chochuluka multimeter tsiku ndi tsiku ali 2.5-bit kusonyezedwa digito, kusonyeza makhalidwe amene molondola ukufika hundredths malo decimal. Pa nthawi yomweyo, 3.5-bit zipangizo linanena bungwe mfundo pa nsalu yotchinga ndi thousandths lapansi.

Kuyesetsa kumvetsa mmene kusankha mita, zochokera magawo a kumaliseche, ayenera kukhala analipira mtengo wa zolakwa alipo. Ngati ndi chidwi, ngakhale n'zotheka thousandths amatsogoza pachionetsero adzakhala kanthu, chifukwa nkhani adzakhala zolakwika.

chakudya

Multimeters ali kumbali-yekha zipangizo. Ambiri mwa ntchitozo ku mabatire ochiritsira. ndi magetsi mwamtheradi okwanira kuti mupeze nthawi yaitali ntchito Tester, ngati n'koyenera, kuchita miyezo banja. Komabe, mu nkhani ya ntchito mita ntchito mafakitale kuti sikokwanira. Pankhaniyi m'pofunika kuletsa kusankha pa Tester, amene okonzeka ndi batire capacitive.

Chiwerengero cha kusonyezedwa

Samalani ulaliki wa makhalidwe akhale olamulira, amene ali kufunafuna Tester ntchito m'malo mafakitale kapena kugwira ntchito ndi avionics zovuta. Select galimoto multimeter choyezera m'malo mwa nthawi zonse zapakhomo kungakhale anasonyeza umodzi. Kukhala zowonetsera angapo digito adzakhala yabwino kwa ogwira ntchito amene ali pa ntchito kunyamula gawo lonse la miyezo osiyana.

Review wa anthu otchuka

Kodi kusankha multimeter galimoto ndi nyumba? Pali zitsanzo zochepa za zinchito ndithu, yosavuta kugwiritsa ntchito testers omwe ali oyenera zolinga zimenezi wamba:

1. ADD8055 - Model multimeter mwapadera kuona ntchitoyo mabatire. Ndi komanso akhoza kuyan'ana magawo opaleshoni ya injini ozizira chiyambi, kulandira deta ku mbali zosiyanasiyana za madera magetsi.
2. ADD280 - chipangizo ntchito oterewa zidutswa za chowala mapulagi mu injini dizilo. Ntchito chipangizo limachititsa kuti azindikire chala sparking m'magulu otere.
3. ADD3055 - matenda Tester phunziro mayunitsi zosiyanasiyana kachipangizo ulamuliro, kachitidwe magetsi a magalimoto. Kufala linafalitsidwa kwambiri ichi chitsanzo multimeter yakhala malo ntchito yokonza magalimoto.
4. ADD8630 - kwa kuwunika mmene luso starters galimoto, magudumu batire. Tester Izi zizindikiro zinchito wagawo mu makina osindikizira, kudzera zomwe n'zotheka kusonyeza zambiri pa pepala.
5. ADD91 - multifunctional dongosolo chingwe chimene chimagwiritsidwa ntchito zamagetsi ndi galimoto zimango. Ndi zizindikiro backlit chiwonetsero ndipo amatha yesezera chizindikiro chimene kubereka masensa zosiyanasiyana.

Malangizo

Potsiriza zoti kusankha mita a galimoto ndi kukhazikitsa ntchito banja ayenera kuganizira malangizo angapo.

Pamene kusonkhana ambiri mtheradi wa testers pakompyuta ntchito tchipisi odalirika. Choncho, kupereka ulemu wapadera kwa kudzazidwa chipangizo si chofunika. Koma kuoneka chipangizo n'kofunika. Choyamba Ndi bwino kuonanso ubwino wa msonkhano. Zigawo za galimotoyo ayenera adzatsekeredwa chikugwirizana. Alendo kupanda mipata, mbali lotayirira ndi mbali yake.

Kodi kusankha multimeter ntchito kunyumba? Pankhaniyi, ndi pulasitiki wamba adzayenerera Tester. Koma akatswiri, yotsirizira bwino kuganizira kugula chipangizo, kudzazidwa mkati chimene akachita mu mpanda womata kugonjetsedwa. Pamene ukugwira ndi multimeter mafomu mafakitale ndi zofunika kuti chipangizo si kuloleza m'chimake mkati fumbi ndi chinyezi.

Kudziwa mita asankhe galimoto ndi nyumba, kulabadira lotuluka masiwichi. Ngati zinthu izi structural anapangidwa ndi osauka khalidwe pulasitiki, izo kumawonjezera mosavuta kuti kwadzaoneni kukhala lotayirira mu miyezi ntchito chipangizo. Motero, kutsatira ndi zokhazikitsidwa lamanja ndi yovuta kwambiri. Choncho ndikofunikira kupereka mmalo multimeters ndi, makamaka masiwichi odalirika zitsulo.

Kumvetsa mmene kusankha multimeter, amene akhala akugwira ntchito tsiku ndi tsiku, muyenera kutembenukira kwa ena zitsanzo pa kanjedza chidwi. Bwino kupereka mmalo chipangizo, amene adzakhala omasuka kugona mu dzanja.

zingwe zilipo ayenera kukhala wabwino mtanda gawo. Nkofunika milandu anthu pamene kuli kofunikira kuchita miyezo ndi mfundo zazikulu.

Ndi zofunika kuti mapeto a kafukufuku bwino chinzake. Zikatero sadzakhala alibiretu mavuto ndi kufunika kumvera zing'onozing'ono mfundo kukhudzana a dera la.

pomaliza

Kotero ife anayang'ana pa mmene kusankha multimeter. Potsiriza Dziwani kuti, ngati n'koyenera, kuchita miyezo zikuluzikulu monga pofuna mlandu batire kapena kuyesa lama fuyusi, ndi bwino kuyang'ana wotsika mtengo testers. Ngati mapulani monga kukhazikitsa mavuto zovuta kwambiri, muyenera kuganizira kugula chipangizo moona multifunctional.
