Maitiro ekuyera DC Voltage neMultimeter (Guide rekutanga)
Zviri mukati
Voltage pamwe ndiyo yakapfava uye inowanzo verengeka kuyerwa kwemultimeter. Nepo kuverenga DC voltage kungaite kunge kuri nyore pekutanga, kuwana kuverenga kwakanaka kunoda ruzivo rwakadzama rweichi basa rimwechete.
Muchidimbu, unogona kuyera DC voltage ine multimeter nekutevera matanho aya. Kutanga, shandura dial kuDC voltage. Wobva waisa iyo nhema inotungamira muCOM jack uye iyo tsvuku inotungamira muV Ω jack. Wobva wabvisa dipstick dzvuku kutanga wozobvisa dipstick nhema. Zvadaro batanidza bvunzo inotungamira kudunhu. Iwe unogona ikozvino kuverenga kuyerwa kwemagetsi pachiratidziro.
Kana iwe uri wekutanga uye uchida kudzidza kuyera DC voltage ine multimeter-zvese dijitari uye analog multimeters - wauya panzvimbo chaiyo. Tichakudzidzisa maitiro ose, kusanganisira kuongororwa kwemigumisiro.
Chii chinonzi constant voltage?
Kuti unzwisise, DC voltage ipfupi fomu yezita rekuti "DC voltage" - voltage inokwanisa kuburitsa yakananga ikozvino. Ukuwo, alternating voltage inokwanisa kugadzira alternating current.
Kazhinji, DC inoshandiswa kutsanangura masisitimu ane polarity anogara aripo. Nekudaro, mune ino mamiriro, DC inonyanya kushandiswa kureva huwandu hune polarity isingachinjiki nguva dzose, kana huwandu hune zero frequency. Huwandu hunogara huchichinja polarity ine yakanaka frequency inonzi alternating current.
Iyo voltage inogona mutsauko / unit charge pakati pezvinzvimbo zviviri mundima yemagetsi ndiyo voltage. Kufamba uye kuvapo kwezvimedu zvinochajiswa (maerekitironi) zvinogadzira simba remagetsi. (1)
Musiyano ungangoita unoitika kana maerekitironi achifamba pakati pemapoinzi maviri - kubva padanho rekuderera kusvika padanho repamusoro. AC neDC mhando mbiri dzesimba remagetsi. (2)
Voltage inotorwa kubva kuDC ndiyo yatiri kukurukura pano - DC voltage.
Mienzaniso yeDC masosi inosanganisira mabhatiri, solar panel, thermocouples, DC majenareta, uye DC magetsi anoshandura kugadzirisa AC.
Maitiro ekuyera DC voltage ine multimeter (digital)
- Chinja dial kuDC voltage. Kana DMM yako ikauya nemamilivolts DC uye usingazive kuti ndeipi yekusarudza, tanga neDC voltage sezvo yakatemerwa kune yakakwira voltage.
- Wobva waisa probe nhema muCOM connector.
- Iwo matsvuku ebvunzo anotungamira anofanira kupinda mukati meV Ω jack. Waita izvi, tanga wabvisa dipstick dzvuku uye wozobvisa dipstick nhema.
- Danho rechina nderekubatanidza ma test probes kudunhu (black probes kune negative polarity test point uye red probes kune positive polarity test point).
Cherechedza. Iwe unofanirwa kuziva kuti mazhinji emazuva ano multimeter anogona kuona otomatiki polarity. Paunenge uchishandisa digital multimeters, iyo tsvuku tsvuku haifaniri kubata iyo yakanaka terminal, uye dema tambo haifanire kubata iyo isina kunaka terminal. Kana probes ikabata zvakapesana nematerminal, chiratidzo chisina kunaka chichaonekwa pachiratidziro.
Paunenge uchishandisa analog multimeter, iwe unofanirwa kuve nechokwadi chekuti madhiri ari kubata iwo chaiwo materminal kuti asakadze iyo multimeter.
- Iwe unogona ikozvino kuverenga kuyerwa kwemagetsi pachiratidziro.
Mazano Anobatsira ekuyera DC Voltage neDMM
- MaDMM emazuva ano anowanzo kuve neauto renji nekukasira, zvichienderana nebasa rinoratidzwa pane dial. Unogona kushandura huwandu nekudzvanya bhatani re "Range" kakawanda kusvika wasvika paunoda. Iko kuyerwa kwemagetsi kunogona kuwira mune yakaderera millivolt DC kuseta renji. Usanetseke. Bvisa ma test probes, shandura dial kuti uverenge millivolts DC, dzorera ma test probes, wobva waverenga kuyerwa kwevoltage.
- Kuti uwane kuyerwa kwakagadzikana, tinya bhatani rekuti "bata". Iwe unozozviona mushure mekunge kuyerwa kwemagetsi kwapera.
- Dzvanya bhatani re "MIN/MAX" kuti uwane yakaderera uye yepamusoro DC voltage kuyerwa, dzvanya bhatani re "MIN/MAX". Mirira beep nguva imwe neimwe iyo DMM inorekodha kukosha kwevoltiji nyowani.
- Kana iwe uchida kuseta iyo DMM kune yakatemerwa kukosha, tinya "REL" (Relative) kana "?" (Delta) mabhatani. Iyo inoratidzira icharatidza zviyero zvemagetsi pazasi uye pamusoro peiyo kukosha kwereferensi.
Maitiro ekuyera DC voltage ine analog multimeter
Tevedza aya matanho ari nyore:
- Dzvanya bhatani rekuti "ON" pamita yako kuti ubatidze.
- Shandura iyo multimeter knob kune "V" chinzvimboDC»- DC voltage. Kana yako analog multimeter isina "VCOLUMBIA REGION,” tarisa kana paine V ine mutsara wakatwasuka wemapoinzi matatu wotendeudzira knob kwariri.
- Ramba uchiseta huwandu, hunofanira kunge hwakakura kupfuura hunotarisirwa kuyedza voltage renji.
- Kana uri kushanda nemhepo isingazivikanwi, iyo yakatarwa inofanira kuva yakakura sezvinobvira.
- Batanidza iyo nhema inotungamira kune COM jack uye iyo tsvuku inotungamira kune VΩ jack (zvichida iyo ine VDC pairi).
- Isa iyo dema probe pane yakaipa kana yakaderera voltage point uye iyo tsvuku probe pane yakanaka kana yepamusoro voltage point.
- Kuti uwedzere kutsauka, izvo zvinobatsira kuvandudza kurongeka, kuderedza voltage renji.
- Zvino tora VDC kuverenga uye chenjera kuti usatore VAC kuverenga.
- Mushure mekunge mapedza kuverenga, bvisai dzvuku probe kutanga uyezve dema probe.
- Dzima multimeter uye wobva waisa iyo yakanyanya kuwanda kudzivirira kukuvara kana ukakurumidza kushandisa zvakare.
Kusiyana nedhijitari multimeter, analog multimeter haina kukuyambira nezve reversed polarity, iyo inogona kukuvadza multimeter. Ngwarira, gara uchiremekedza polarity.
Chii chinonzi overload mamiriro uye anoitika riini?
Pane chikonzero chakanaka nei uchirayirwa kuti usarudze voltage renji pamusoro pemutengo unotarisirwa. Kusarudza kukosha kwakaderera kunogona kukonzera kuwandisa. Iyo mita haigone kuyera voltage kana iri kunze kweyekuyeresa.
PaDMM, iwe unozoziva kuti uri kubata nekuremerwa mamiriro kana iyo DMM ikaverenga "kunze kwerenji", "OL" kana "1" pachiratidziri. Usavhunduka kana iwe wawana overload chiratidzo. Haikwanise kukuvadza kana kukuvadza iyo multimeter. Iwe unogona kukunda mamiriro aya nekuwedzera huwandu nesector knob kusvika wasvika kukosha kwaitarisirwa. Kana iwe uchifungidzira kudonha kwevoltage mudunhu rako, unogona zvakare kushandisa multimeter kuyera.
Paunenge uchishandisa analog multimeter, iwe unozoziva kuti une yakawandisa mamiriro kana iwe ukaona iyo "FSD" (Yakazara Scale Deflection) museve. Mune analog multimeters, kuremerwa mamiriro anofanirwa kudzivirirwa kudzivirira kukuvara kunogona kuitika. Gara kure ne low voltage ranges kunze kwekunge uchiziva kuyera voltage.
Security Council: Dzivisa masensa ane waya dzakaputsika kana dzisina. Pamusoro pekuwedzera kukanganisa pakuyera kuyerwa kwemagetsi, maprobes akakuvadzwa ane njodzi pakuyera magetsi.
Kunyangwe iwe uri kushandisa dhijitari multimeter kana analog multimeter, iwe zvino wave kuziva kuti multimeter inoyera sei voltage. Iye zvino unogona kuyera ikozvino nechivimbo.
Kana iwe ukapa kutarisisa kwako kuzere kune maitiro, wagadzirira kuyera voltage kubva kuDC sosi. Zvino chiyera voltage kubva kune yako yaunofarira DC sosi uye uone kuti inoshanda sei.
Isu takanyora mashoma akawanda multimeter tutorials pazasi. Unogona kutarisa nekuabhukimaka kuti uverenge gare gare. Ndatenda! Uye tinokuona munyaya yedu inotevera!
