Maitiro ekuyera zvazvino ne multimeter (2-chikamu chidzidzo)

Paunenge uchishanda purojekiti yemagetsi, ungada kutarisa huwandu hwezvino kana simba rinoyerera kuburikidza nedunhu. Iwe zvakare unofanirwa kuyera iyo amperage kuti uone kana chero chinhu chiri kutora simba rakawanda kupfuura zvarinofanira.

Kuyera ikozvino kunogona kubatsira kana uchiedza kuona kana chikamu chiri mumotokari yako chiri kudhonza bhatiri rako.

Neraki, kuyera ikozvino hakuna kuoma kana iwe uchiziva iwo ekutanga multimeter bvunzo uye unongwarira kutenderedza zvinhu zvemagetsi.

Rega ndikubatsire kudzidza kuyera maamps ane multimeter. 

Precautions

Iwe unofanirwa kungwarira kana uri kushandisa iri nyore multimeter kana yedhijitari multimeter. Paunenge uchiita zviyero zvemagetsi, kuyerwa kwega kwega iko kushandiswa kunopa njodzi dzinogona kuitika dzinofanirwa kutariswa. Usati washandisa chero midziyo yekuyedza yemagetsi, vanhu vanofanirwa kugara vachiverenga bhuku remushandisi. Zvakakosha kudzidza nezve maitiro akakodzera ekushanda, kuchengetedzwa kwekuchengetedza uye zvirambidzo. (1)

Pfeka magirovhosi erabha anorema, dzivisa kushanda pedyo nemvura kana nzvimbo dzesimbi, uye usabate waya dzisina chinhu nemaoko. Zvakanakawo kuva nemunhu pedyo. Munhu anogona kukubatsira kana kufona kuti ubatsirwe kana wabatwa nemagetsi.

Multimeter kugadzirisa

Nhamba 1. Tsvaga kuti mangani amp-volts bhatiri rako kana redunhu rinotyora rinogona kubata pane nameplate.

Ita shuwa kuti multimeter yako inoenderana nehuwandu hweamps inoyerera kuburikidza nedunhu usati waibatanidza nayo. Inoratidza iyo yakayerwa yakanyanya ikozvino yeakawanda magetsi emagetsi, sezvakaratidzwa pane nameplate. Kuseri kwechiridzwa kana mubhuku rekushandisa, unogona kuwana huwandu hwazvino hwemataya e-multimeter. Iwe unogonawo kuona kuti chiyero chinokwira sei. Usaedze kuyera macurrents pamusoro pehuremu hwechiyero chepamusoro. 

#2 Shandisa plug-in clamps kana yako multimeter inotungamira isina kukwira zvakakwana kudunhu. 

Isa mawaya mumultimeter uye batanidza kudunhu. Ita izvi nenzira imwecheteyo sepa multimeter clamps. Putira chisungiso pawaya mhenyu kana inopisa. Inowanzova dema, tsvuku, bhuruu, kana rumwe ruvara kunze kwechena kana girini. Kusiyana nekushandisa multimeter, zvisungo hazvizove chikamu chedunhu.

Nhamba 3. Isa iyo dema bvunzo inotungamira mune multimeter's COM port.

Kunyangwe kana uchishandisa jig, yako multimeter inofanirwa kunge iine tsvuku uye dema inotungamira. Iyo probe ichavawo netipi kune imwe mugumo wekukochekera muchiridzwa. Iyo dema bvunzo lead, inova waya isina kunaka, inofanirwa kugara yakavharirwa muCOM jack. "COM" inomirira "common", uye kana chiteshi chisina kunyorwa nacho, unogona kuwana chiratidzo chisina kunaka panzvimbo.

Kana waya dzako dziine mapini, unozofanirwa kudzichengeta munzvimbo yekuyera ikozvino. Iwe unogona kusunungura maoko ako nekuvasungirira kune cheni kana vaine zvimedu. Nekudaro, ese ari maviri marudzi eprobes akabatana nemamita nenzira imwechete.

Nhamba 4. Isai probe yakatsvuka muchigadziko "A".

Unogona kuona zvitoro zviviri zvine vara "A", imwe yakanzi "A" kana "10A" uye imwe yakanzi "mA". mA outlet inoedza milliamp kusvika pa10 mA. Kana usina chokwadi chekushandisa, sarudza yakakwira "A" kana "10A" kudzivirira kuwandisa mita.

Nhamba 5. Pamamita, unogona kusarudza AC kana DC voltage.

Kana mita yako iri yekuyedza AC kana DC maseketi chete, uchafanirwa kusarudza kuti ndeipi yauri kuyedza. Kana iwe uchiri kusava nechokwadi, tarisa chinyorwa pane magetsi zvakare. Izvi zvinofanira kutaurwa pedyo nevoltage. Yakananga ikozvino (DC) inoshandiswa mumotokari uye midziyo ine simba rebhatiri, nepo alternating current (AC) inowanzoshandiswa mumidziyo yemumba nemamota emagetsi.

Nhamba 6. Munguva yekuyera, isa chiyero kune yakakwirira ampere-volt level.

Kana uchinge waverenga mafungu epamusoro ekuyedza, tsvaga lever pamamita ako. Tenderedza zvishoma kudarika nhamba iyi. Kana iwe uchida kungwarira, shandura dial kusvika pakakwirira. Asi kana iyo yakayerwa voltage yakadzikira, haugone kuverenga. Kana izvi zvikaitika, iwe uchafanirwa kudzikisa chiyero uye kutorazve basa racho.

Nzira yekuyera sei volt-ampere ne multimeter

Nhamba 1. Dzima simba redunhu.

Kana dunhu rako richifambiswa nebhatiri, bvisa tambo isina kunaka kubva mubhatiri. Kana iwe uchida kudzima magetsi ne switch, dzima switch, wobva wabvisa mutsara wakatarisana. Usabatanidza mita kudunhu kana magetsi ari.

Nhamba 2. Bvisa tambo tsvuku kubva kune magetsi.

Kuyera ikozvino inoyerera kuburikidza nedunhu, batanidza multimeter kuti upedze kosi. Kutanga, dzima simba kudunhu, wozobvisa waya yakanaka (tsvuku) kubva kune simba. (2)

Ungada kucheka waya newaya cutters kuti udambure cheni. Ona kana paine plug panosangana tambo yemagetsi newaya inoenda kune gadget ichiedzwa. Ingobvisa chivharo uye sunungura tambo dzakatenderedza mumwe nemumwe.  

Nhamba 3. Bvisa magumo ewaya kana zvichidikanwa.

Putira waya shoma kutenderedza mapini emultimeter, kana kusiya waya akakwana pachena kuitira kuti mapini ealligator avhare akachengeteka. Kana waya yakavharwa zvachose, tora makucheka ewaya anenge 1 inch (2.5 cm) kubva kumagumo. Svina zvakaringana kuti ucheke mukati merubha insulation. Wobva wadhonza mawaya ekucheka nekukasira kwauri kuti ubvise insulation.

Nha. 4. Putira mutezo wakanaka wekuedza we multimeter newaya yakanaka.

Putira kumagumo kwewaya dzvuku netambo tepi kure nepanotangira magetsi. Natanidza zvimedu zvealligator pawaya kana kuputira muromo wemultimeter probe uchiitenderedza. Chero zvazvingava, kuti uwane chigumisiro chakarurama, iva nechokwadi chokuti waya yakachengeteka.

Nhamba 5. Simbisa dunhu nekubatanidza dema probe ye multimeter kune yekupedzisira waya.

Tsvaga waya yakanaka inouya kubva kumagetsi ekuyedzwa uye woibatanidza kune nhema muromo wemultimeter. Kana ukabvisa tambo kubva kubhatiri powered circuit, inozowanazve simba rayo. Batidza magetsi kana wadzima nefuse kana chinja.

Nhamba 6. Paunenge uchiverenga mita, siya zvigadziri panzvimbo kweinenge miniti.

Kana iyo mita yaiswa, iwe unofanirwa kuona nekukurumidza kukosha pakuratidzira. Ichi chiyero chezvino kana chazvino chedunhu rako. Pakuyera kwakanyatso kujeka, chengeta michina ichitenderera kweinenge miniti 1 kuti uone kuti iripo yakagadzikana.

Unogona kutarisa mamwe multimeter bvunzo isu takanyora pazasi;

• Maitiro ekushandisa multimeter kutarisa voltage yewaya mhenyu
• Nzira yekugadzira amplifier ine multimeter
• Nzira yekutsvaga waya ne multimeter
