Digital Multimeter DT-830B: User manual, uye wongororo

Multimeter DT-830B - Chinese-yakaitwa mudziyo, iro rinoshandiswa zhinji. Vaya vanogara anobata zvemagetsi, haagoni kuita pasina michina yakadaro. Nyaya ino inotsanangura kuti Multimeter DT-830B. Instructions nezvechiratidzo mudziyo anobvumira kushandiswa kwayo kunyange beginners.

Available muri mhando dzakawanda kuti akasiyana nounhu, zvakarurama uye functionality.

The mudziyo iri aiendeswa zvinotevera nezviyero dzinokosha:

• Magetsi tsika;
• voltage pakati mbiri pfungwa iri kutenderera magetsi;
• nemishonga.

Uyezve, DT-830B Multimeter nemamwe mhando zvakafanana kunogona kuita mamwe mabasa mazhinji:

• kuti mhete redunhu kana impedance pazasi 50 ohms ane aramu;
• achiedza uye kuona kwayo mberi voltage kutendeseka chinhu semiconductor diode;
• tarisa semiconductor transistor;
• kuyera kuti capacitance uye inductance;
• tembiricha akayera pedyo thermocouple;
• kuona harmonic chiratidzo maitikiro.

ari multimeter sei?

1. Dial anoratidza akayera tsika muchimiro nhamba iri mapurasitiki kana girazi kuratidza.
2. The chinja inopa kuchinja mudziyo mashandiro, uyewo chinja neeSultan. zvinonzi wakaiswa kuti "Off" iri simbe mamiriro.
3. Matendere (connector) nokuti kugadzwa ari redzimba zvinoisa. The chikuru chinhu neshoko ru uye kunaka polarity, ndiye utility. Zvinonzi akaiswa mukati vachiongorora pamwe dema waya. Next, kwakaratidzwa VΩmA, ine yakanaka polarity red vachiongorora.
4. The bvunzo tefa waya dzvuku uye rikasviba zvikwekwe.
5. Emadziro nokuti kutonga transistors.

Multimeter DT-830B: User Chinyorwa nematsananguriro hwakadzama yakayerwa modes

Havasi vose anoziva kuyera zvakakodzera parameters ari mudziyo. Kana uchishandisa DT-830B meter, anodawo mirayiridzo zvinofanira kutevedzerwa nemazvo. Zvikasadaro, kuti midziyo itsvuke kunze.

1. Kuyerwa kurwisa

Basa kunokosha kana uchida kuchengetedza wiring mu mufurati kana kuwana yokumbozorora musha Network. Haasi munhu wose anoziva, muchiitiko ichi, kushandisa multimeter, uye unotofanira yokugadza chinja kuti kurwisa kuyerwa kwemauto pamusoro zvakakodzera kuyerwa-siyana. The mudziyo ine ruzha zvichiratidza kuti redunhu yapera. Kana chiratidzo asipo, izvi zvinoreva kuti pane pane mukaha kana wakakwirira nemishonga ukoshi redunhu 50 ohms.

The siyana shoma kurwisa (200 ohms) ndiyo pfupi-circuited. Kana interconnect tsvuku uye dema bvunzo, huchashandiswa ane kuratidza kukosha pedyo razero.

Multimeter DT-830B Chinese gadzira ane zvinotevera zvinhu apo kuyera yemagetsi nemishonga:

1. A mukuru kuverenga kururama.
2. Kana kuyera impedances diki kubva mukuverenga anofanira subtracted ukoshi yakawanikwa panguva kuonana Yatanga Kuongorora. Kuti vaite izvi kare kuvharwa. Kune dzimwe neeSultan nemauto kukanganisa ipfupi.

2. kuyera DC voltage

The mudziyo haizoshandisi kuti DCV kwemauto rakakamurwa 5 zvisungo. The chinja wakagarira kuti nemaune hombe-siyana zvinokosha. Kana kuyera voltage kusvitsa kubva bhatiri 3 kana 12 anogona kuiswa nemauto chinzvimbo "20". haafaniri kuiswa pane imwe huru kukosha, sezvo kuwedzera kuverenga kukanganisa uye itsvuke panguva yakaderera chimwe. Kutsauka kuyerwa, kana uchida zvakarurama 1 chete, kuti mita anogona kuiswa zvakananga nezvenzvimbo "500". Saizvozvowo, haazivi kana akayera voltage nokukura. Unogona ipapo zvishoma nezvishoma chinja chikuva kuti yakaderera tsika. On yokumusoro chechetere kuyerwa anonongedzera nyevero "HV", iro rinovheneka iri repamusoro rworuboshwe wekona. voltages Large zvinoda zvaidiwa kungwarira kushanda pamwe nenhumbi, asi somunhu voltmeter Multimeter DT-830B zviri zvikuru yakavimbika kupfuura ammeter kana ohmmeter.

Compliance Yatanga Kuongorora polarity optionally digitaalinen mudziyo. Kana asingadi kunowirirana nomusi uchapupu kukosha haangazozikamwi kukanganiswa, uye vasara chidzitiro ichivhenekera kukwira chiratidzo "-".

3. kuyera AC voltage

Installation iri Shona kwemauto kwakafanana muna DCV. High voltage 220-380 B kunogona kukonzera kukundikana mudziyo nokuda sizvo kubatana.

4. Kuyerwa DC

Small dzenzvimbo kune zvemagetsi nematunhu vari akayera muna DCA zvekutepfenyura. In izvi ufambe zvinzvimbo zvisingagamuchirwi voltage chipimo. Muchiitiko chino, dunhu pfupi kunoitika.

Kuyera kukosha kwazvino 10 A ndipiyona chigaro wechitatu, izvo zvinofanira kugara tsvuku vachiongorora. Zvairatidza anogona kubviswa mumasekonzi mashomanana. Yemanyorero imwe ammeter kuyerwa magetsi iyezvino. Kushandisa mudziyo iyi, hanya zvinofanira kutorwa uye kana kuyerwa inodiwa.

5. Zvakanaka diodes

Mugore neizvi vatungamirire diode mudziyo vanofanira kuratidza kusaverengeka (kuruboshwe chikwata). Ari mberi voltage mhiri mhesano ndiyo 400-700 MV.

In kwemauto ichi unogona kutarisa serviceability yacho transistor. Kana achimiririrwa yaisanganisira mbiri pakatarisana diode, zvinokosha kuona mumwe Kuchinja panguva Kuparara. Kuti aite izvi, zvinova pachena apo nechepasi. Nokuti pnp mhando zvinofanira ndinoiitawo-vachiongorora kuwana mhedziso zvakadaro (chawo) kuti vachiongorora akaratidza kunaka kusaverengeka kune mamwe maviri (emitter uye nomuteresi). Kana transistor ndiko mhando npn, nechigadziko ndiko kubvisa vachiongorora. Kuti tiwane emitter, zvakakodzera kuyera nemishonga yayo sanduko, inova nguva dzose kupfuura nemuteresi. Nokuti basa chaikosha zvinofanira kuva kuwanda 500-1200 ohms.

Prozvoniv kuchinja multimeter mu mberi uye kuzvishandura mirayiridzo, zvinokwanisika kuti kuziva chakaremara transistor kana kwete.

6. hFE Sector

The Chishandiso anogona kuona kuitika amplification chinhu h21-transistor. Zviri zvokuti vanoramba 3 Pins akakodzera Jack zvigadziko. The Kuratidzwa ukoshi rinowanika pakarepo "h21". Kuti vawane zvakarurama zvabuda zvakakodzera kusiyanisa mhando pnp (kurudyi ukomba) uye npn (kuruboshwe divi).

7. yaibvira kuvandudza mudziyo

On Multimeter DT-830B Instructions anopa imwe nhamba mitambo. The mhando akasiyana mumwe zvishoma, uye kana achida, chero inogona akavandudzika, akadai achiwedzera capacitance kuyerwa, tembiricha uye zvose zvimwe mamwe mabasa pamusoro apa.

Description Multimeter DT-830B mune zvokushambadzira uye wongororo zvachose nhema.

Hwaro multimeter chinhu analoginen-kuti-digitaalinen convert (ADC).

Multimeter DT-830B: redunhu uye kugadzira

For rweruzhinji inotakurika Chishandiso anowanzodanwa kushandiswa Chip ICL7106.

In nokuyerwa ari voltage chiratidzo akatumira kubva chinja kuburikidza resistor R17 kuti mazano 31 chip. Kana rakatumbuka voltage kunoyerwa, richiwanika kuburikidza rectification diode D1, dzakatsigira cheni chiratidzo uyewo anoenda mhedziso 32 Chips.

Akayera DC razvino pave voltage donhwe mhiri resistors, uye ipapo chiratidzo iri zvokudya kune mazano dziviriro redunhu 32. The fiyuzi chakagadzirwa 0.2 A yakatarwa chiyamuro.

The mudziyo kazhinji anotadza kurasikirwa vokukurukura uye kana kwete zvakanaka dzikava pamusoro. Chokutanga, tarisa uye kushandura fiyuzi.

The mudziyo anoshanda yakavimbika mune nokuyerwa voltage, uyewo anodzivirirwa overloads pamusoro chiyamuro. Kukundikana kunogona kuitika panguva kurwisa kana ano chipimo.

Vakapisa resistors inogona vakatsunga nemaziso, uye diodes uye transistors vari kuedzwa kushandisa nzira dzakapiwa kumusoro. Macheki pamusoro chamazuva uye rakavimbika vokukurukura.

Kana rokugadzirisa mudziyo wokutanga achaongorora simba rive. Zvadaro kugadzira Chip iri achiongorora. Inofanira kuva shandika, kana voltage panguva chinouraya 30 ndiyo 3 V, uye pakati nesimba chinouraya uye vanhuwo Chip hapana Kuparara.

Kana disassembling kuti chinja arege kurasikirwa marozari, pasina izvo hazvina akavimbika Kuda kutamba.

Kana kushandura bhatiri?

Power zvitengeswa dzinosiyana nyaya kunyangarika nhamba kuratidzwa uye kutsauka yakayerwa zvabuda kubva anozivikanwa anofungidzirwa tsika. Battery mufananidzo anozviratidza pamadziro. Kuritsiva unofanira kubvisa yokupedzisira, kubvisa mutana uye kuisa chinhu chitsva.

Shandisa multimeter DT-830B ari nyore chaizvo bhatiri kuchinja nyore uye mashoma chaizvo. Chete vanofanira kushanda naye akatibvunzisisa. Mudziyo anogona kupisa nyore kana akashandiswa zvisiri.

Reviews of mudziyo

On zano akadai digital multimeter DT-830B, kunyanya nyaya dzinovaka. Ndiye vane mwero, ichiita mabasa akawanda, uye matochi kunotora kwemakore. Rinoronga zvose pasi mutengo mudziyo. Comments chete kuonekwa pamusoro pezvisingakoshi.

Yatanga Kuongorora aifanira kutsiviwa, sezvo vari zvikuru nyore sousingabatsiri. Nemishonga navo uye pedyo mureza ndiwo 0.5 ohms.

mhedziso

Multimeter DT-830B ari mudziyo inoshanda, zvakafanira kuti DIY uye nounyanzvi. Une zvakawanda zvinokosha mabasa uye yakachipa. To zvinobudirira kushandisa zvakakodzera kudzidza zvose chii Multimeter DT-830B. The kushanda Mirayiridzo anofanira takanyatsoomerera kudzivisa chero zvikanganiso zvingatungamirira kukundikana mudziyo.
