Kodi kufufuza mikuza mawu multimeter? malangizo

Multimeter otchedwa chida chimene anayeza voteji, panopa, kukana, anachita "kupitiriza" a mawaya. Ndiko kuti, chipangizo ichi ndi kufunika chokwanira. Ndipo ikusonyeza kuchita, kuti amakonda okwanira otchuka osati mafakitale komanso moyo wa tsiku ndi tsiku.

Koma musanayambe muyeso, tisaiwale kuti multimeter - chipangizo osati kwenikweni vuto lililonse. Pamene ntchito molakwika, osati mosavuta kuletsa izo, komanso amavutitsa kwambiri thanzi lanu. Izi ndi zoona makamaka mu nthawi imene mukufuna kugwira miyezo pa voteji mkulu kapena mkulu amperage. Inu simungakhoze basi pomwepo kuwotcha mita, komanso kulandira lalikulu mantha magetsi.

N'chifukwa chake, musanayambe kugwiritsa ntchito mita, muyenera aphunzitsidwe pa katundu mphamvu ndi ntchito otsika panopa, monga batire. Muyeneranso kunyalanyaza malangizo kwa chipangizo.

mitundu multimeters

Kuyamba, muyenera kudziwa kuti multimeters ndi digito ndi analogi (muvi uliwonse, ngakhale pakati pa zamagetsi amadziwika ngati "tseshka"). zamagetsi chachiwiri amadziwika kwa nthawi yaitali, koma adzawagwiritsa ntchito mopanda nzeru zapadera ndi kuchita ndi zovuta.

• ayenera kumvetsa lonse chipangizo, kumene Pepala multimeter angapo;
• chida ayenera kuonedwa zimenezo, pamene palibe mivi kuti "kuyenda" pa sikelo ya.

N'chifukwa chake, ngati pali kuthekera amenewa, ndi bwino ntchito multimeter yadigito. Tionanso zitsanzo ntchito monga chipangizo digito mmene umadzikondera wekha kuphunzira ntchito wokongola kwambiri multimeters analogi.

Zosiyanasiyana digito multimeters zokwanira, koma momwe ntchito ndi ofanana ndi munthu wina - kusiyana ndi chokha chiwerengero cha ntchito chipangizo. Choncho, kuchokera multimeter magwiridwe ndi mtengo zimadalira, kotero pamaso panu kugula izo, kusankha chimene icho chiri mukufuna.

mita tichipeza:

• chipangizo palokha;
• probes awiri (wofiira ndi wakuda);
• mphamvu zoyendetsera (batire "Korona" 9b).

Choncho, kodi mbali ya ntchito choyezera chida ndi momwe fufuzani mikuza mawu multimeter?

malangizo

Kuti ayeze pano mu dera la, m'pofunika sequentially kulumikiza chipangizo thereto. Pa nthawi yomweyo pa multimeter n'kofunika kuti zili wofiira mu zitsulo pa chida ndi kuwanena MA, ndi wakuda - mu kathakal. kugwirizana siriyo zikutanthauza kuti unyolo ayenera wosweka ndi aliyense kafukufuku amamangiriridwa waya osiyana, T. E. chipangizo ayenera olumikizidwa pakati magwero mphamvu ziwiri. Koma ngati mukufuna kuyeza mphamvu ya pano, ndipo mphanvu si magwero zotheka, muyenera kuwasandutsa unyolo ena chipangizo, monga ochiritsira getsi, kuwayika mu dera yomweyo pambuyo gwero mphamvu.

Ngati inu anayeza AC mphamvu, chipangizo amamasulidwa pa mtengo pazipita wa AC (chizindikiro A ~ - dziwani kuti ndi ofanana kwambiri kwa DC chizindikiro (A), choncho samalani). Ndipo pambuyo kuti mukhoza kuyamba miyezo.

Musanayambe onani ampere multimeter, onetsetsani kuti mphamvu ya pano limatanthauza si kwambiri, mwachitsanzo. A., miyezo zimenezi sizingakhale otetezedwa chifukwa cha yaing'ono mtanda gawo la mawaya kafukufuku. Yotsirizira sangaime katundu mkulu. Akatswiri amalangiza kuchita miyezo pa mtengo panopa 10 A kopanira pa.

Chongani batire multimeter

Macheke ayenera kuchitidwa kokha pansi pa katundu. Chongani angati amperes batire multimeter okha ntchito mkati mphamvu batire sizingatheke chifukwa cha phindu lake otsika - chifukwa kanjedza chiyani silisonyeza kanjedza woona.

Tester angathe kuyeza osati panopa opaleshoni, komanso kutayikira panopa batire la. Musanayambe onani multimeter wanu monga amperes wa kutayikira panopa, muyenera kukumbukira kuti n'kutheka kuti amperes angapo. Choncho kuvala muyeso osiyanasiyana chida ayenera kukhala molondola, ndi bwino 10 A.

Zochita pamaso mayeso pa batire la mikuza mawu multimeter wakwezedwa ndi malo batire la chingwe batire zabwino ndi monga mwa chotsatira kusiyana kuyeza chipangizo. Ndiye muyenera:

• kusankha mode pa multimeter kuti kuyeza panopa;
• kukonza "ng'ona" waya ndi alternately kukokera mafyuzi, amene ali ndi udindo kwa gawo amagetsi mu galimoto.

Ndi zina zokhudzana, inu osati kudziwa momwe fufuzani mikuza mawu multimeter, komanso mosavuta kudziwa chifukwa cha kutayikira, popanda kuwaika malo utumiki.

afufuze naupereka

Pamaso kuyankha funso: "Kodi kufufuza mikuza mawu multimeter pa naupereka," inu muyenera kudziwa kuti mungathe kuyeza, mfundo, adzapereke iliyonse. Zimakhala ku foni kapena piritsi, naupereka kwa batire la galimoto, ndi zina zotero. D.

Phone Charger

miyezo oterewa nthawi zambiri chofunika pamene kuli kofunikira kupeza chifukwa cha vuto kukumbukira. Tikumbukenso kuti mphamvu panopa mu chargers foni, miyala ndi zina zotero. E. Pang'ono osiyana ndi nthawi anasonyeza pa naupereka chizindikiro kapena chodetsa. Koma ngati palibe chizindikiro ngati pazifukwa zosiyanasiyana, ndiye inu angaletse ichi chithunzi multimeter.

Mfundo akayezetsa chakuti naupereka kwa akhoza kusiyana kokha chifukwa chakuti ali ovuta kulumikiza iwo probes multimeter chifukwa cha kukula ka ojambula pa cholumikizira cha. Kuti zimenezi zitheke, ojambula pamafunika anaikapo wamba zitsulo singano ndipo iwo kugwirizana multimeter probes. Ngati sichoncho, ndiye mwina yekha adzapereke kutsegula kwa nyumba kugwirizanitsa probes mwachindunji malo kukumbukira pa malo malekezero ali soldered chingwe magetsi.

Naupereka kwa batire la galimoto

Tisanafotokoze kulankhula za mmene fufuzani mikuza mawu pa multimeter naupereka kwa batire la galimoto, muyenera kudziwa, kodi kuchita.

Mtengo mulingo woyenera kwambiri adzapereke panopa kukumbukira ndi 10% wa mphamvu ya batire la galimoto. Phindu lalikulu amalola mofulumira recharge batire, koma zoipa bwanji batire palokha, ndipo kuchepetsa nthawi ya ntchito.

Pamene kugula kukumbukira ngati kusunga magawo onse olembedwa pa naupereka kwa. Koma ngati mlandu, ndi chidziwitso kochepa zikhoza kuchitidwa paokha. Pankhaniyi mungathe imathandiza multimeter. Komanso, mita lipindulitsa ngati kukumbukira kwalephera.

Izo ziyenera kuti pamene kuyeza amperage wa chargers aliyense mu dera la pazikhalanso katundu aliyense (mwachitsanzo, wamba getsi). Komanso, musaiwale kuti kukumbukira kaŵirikaŵiri zimapereka panopa zonse, choncho cholembera mita ayenera poyera kuti malo zolondola (A).

Chongani magetsi

Kodi kufufuza mikuza mawu multimeter pa magetsi? Izi zachitika monga kwamakokedwe katundu chofunika ntchito. Mfundo pakokha wosiyana kwambiri afufuze zina. Ndikofunikira kudziwa kuti PSU ali ndi mphamvu m'malo chachikulu, kotero miyezo ayenera idzachitika yatetsedwa mwachangu, popanda probes Kutentha mawaya multimeter.

Monga tikuonera, mita kungakhale kothandiza kwambiri pa moyo ndi mu ankafuna m'madera chosiyana, kotero kupeza chidziwitso kwambiri kochepa ntchito zake sadzakhala zosafunika.
