Chii chinonzi multimeter?
Multimeter chishandiso chekuyeresa chinogona kuyera akasiyana hunhu hwemagetsi senge voltage, kuramba, uye ikozvino. Chishandiso ichi chinonziwo volt-ohm-millimeter (VOM) nekuti chinoshanda se voltmeter, ammeter, uye ohmmeter.
Mhando dze multimeters
Midziyo yekuyeresa iyi inosiyana muhukuru, zvimiro nemitengo uye zvakagadzirirwa kutakurwa kana kushandiswa patafura zvichienderana nekwavanoda kushandiswa. Mhando dze multimeter dzinosanganisira:
- Analog multimeter (dzidza kuverenga pano)
- Dhijitari multimeter
- Fluke multimeter
- Clamp multimeter
- Automatic multimeter
Iyo multimeter ndeimwe yeanonyanya kushandiswa ekuyeresa zviridzwa mazuva ano. Zvisinei, vanotanga vanowanzoona zvakaoma kuziva zviratidzo pane multimeter. Muchikamu chino, tichakuratidza maitiro ekuziva mavara pane multimeter.
Kunyangwe mhando dzakasiyana dzemamultimeter dziripo pamusika, vese vanoshandisa iyo yakafanana chiratidzo system. Zviratidzo zvinogona kukamurwa kuita zvikamu zvinotevera:
- On/off icon
- gate icon
- Voltage chiratidzo
- Chiratidzo chazvino
- Resistor chiratidzo
Zvinoreva zviratidzo pane multimeter
Zviratidzo zviri mu multimeter zvinosanganisira:
| Symbol | System functionality |
| BATA bhatani | Inobatsira kurekodha uye kuchengetedza yakayerwa data. |
| On/off button | Vhura, dzima. |
| COM port | Inomirira Common uye inenge nguva dzose yakabatana pasi (Ground) kana cathode yedunhu. Iyo COM port inowanzova dema muruvara uye zvakare inowanzobatanidzwa kune dema probe. |
| chiteshi 10A | Ichi chiteshi chakakosha, chinowanzo gadzirirwa kuyera makwikwi akakwira (> 200 mA). |
| mA, μA | Yakaderera ikozvino kuyerwa chiteshi. |
| mA ohm port | Iyi ndiyo chiteshi iyo iyo tsvuku probe inowanzobatanidzwa. Ichi chiteshi chinogona kuyera ikozvino (kusvika ku200mA), voltage (V), uye kuramba (Ω). |
| chiteshi oCVΩHz | Iyi ndiyo chiteshi chakabatanidzwa kune red test lead. Inokubvumira kuyera tembiricha (C), voltage (V), kuramba (), frequency (Hz). |
| Chokwadi RMS Port | Kazhinji yakabatanidzwa kune tsvuku tsvuku. Kuyera iyo yechokwadi mudzi inoreva square (yechokwadi RMS) parameter. |
| SELECT bhatani | Inobatsira kuchinja pakati pemabasa. |
| kupenya | Gadzirisa kupenya kwechiratidziro. |
| Magetsi makuru | Alternating current. Zvimwe zvigadzirwa zvinongonzi A. |
| DC voltage | D.C. |
| Hz | Edza kuwanda kwehuwandu. |
| DUTY | Kuyera kutenderera. Edza ikozvino capacitance. Tarisa kuenderera mberi, pfupi pfupi (Kuenderera mberi cheki). |
| bhatani rechiratidzo | Diode Test (Diode Test) |
| hFE | Transistor-transistor bvunzo |
| BSN | Kwete-inobata ikozvino induction basa |
| REL bhatani (hama) | Seta kukosha kwereferensi. Inobatsira kuenzanisa uye simbisa zviyero zvakayerwa zvakasiyana. |
| RANGE bhatani | Sarudza nzvimbo yekuyera yakakodzera. |
| MAX / MIN | Chengetedza hukuru uye hushoma hwekupinza hutsika; Beep chiziviso kana kukosha kwakayerwa kwakadarika kukosha kwakachengetwa. Uye ipapo kukosha kutsva uku kunonyorwa pamusoro. |
| Chiratidzo Hz | Inoratidza kuwanda kwedunhu kana mudziyo. |
Kushandisa multimeter?
- Inoshandiswa kuyera voltage, semuenzaniso: kuyera DC ikozvino, AC ikozvino.
- Edza kupikisa nekusingaperi voltage, ikozvino uye ohmmeter duku.
- Inoshandiswa kukurumidza kuyera nguva uye kuwanda. (1)
- Kukwanisa kuongorora matambudziko emagetsi edunhu mumotokari, tarisa mabhatiri, alternators emota, nezvimwe. (2)
Ichi chinyorwa chinopa zvese tsananguro yezviratidzo zvekureva kuziva zviratidzo zvese zvinoratidzwa pane multimeter. Kana takapotsa imwe kana zano, inzwa wakasununguka kutitumira email.
