Karin Daidaita da Turuwa a Matattaka?

Digital Multimeter shine wani tashar da labaran da suka fi sune: Digital da Multimeter. Za mu iya duba kuma fahimta cewa suna da suwa wannan labari, wanda yana taimaka muka son in fahimta wa multimeter ya yi wa. Labarin da ya dace - digital - yana nuna cewa takardunakinsu na digital ko liquid crystal display, saboda haka labarin da ya biyu - multimeter - yana nuna cewa wani abin da za a yi shi zai iya amfani da shi don inganta masu alama. Wani digital multimeter zai fi bayyana kamar Figure 1, wanda yake da switchin zabi, takardunakin, portoki da kuma probes.

Duk da haka, digital multimeters ana amfani da su don bincike ukuwar masu muhimmanci, kasar karamin, tension da resistance. Daga baya, su na iya amfani da su don karfi masana'antar diode, capacitance measurement, Transistor hFE ko DC current gain, frequency measurement da kuma continuity check. A nan, za a bayyana littafi mai tsawo game da amfani da multimeter don bincike karamin, tension, resistance, diode da kuma continuity checks.

Bincike Karamin Tare Da Digital Multimeter

A kan kungiyar, digital multimeter yana haɗa da ammeter saboda an amfani da shi don bincike karamin. Don in iya haka, za ku fadada probe na lafiya ta multimeter zuwa wata soketin da keke karamin: mA (don bincike karamin da ya fi) ko 20 A (don bincike karamin da ya guda). Sambarta meter a kan line da keke karamin (series connection). Bayyana range na yadda ake yi a amfani da shi a section na ammeter ta Figure 1. A wannan yanayin, idan ake faɗi power supply, meter yana bincika karamin da keke a circuit.

Bincike Tension Tare Da Digital Multimeter

Idan ake saka don bincike tension, multimeter yana haɗa da voltmeter. Idan za ku faru, za ku fadada red da black probes zuwa soketin da aka marka 'V' da 'COM', respectively. Bayyana range na yadda ake yi a section na voltmeter ta Figure 1. Samun AC ko DC. A wannan yanayin, meter yana bincika value na tension, idan ake sambarta leads across component (parallel fashion) ko a wurin da ake yi bincike.

Bincike Resistance Tare Da Digital Multimeter

A kan kungiyar, an saka multimeter don haɗa da ohmmeter. Red da black probes zuwa soketin da aka marka 'V' da 'COM', respectively, bayyana range na ohmmeter region (Figure 1). Leads sambarta across component da ake yi bincike resistance. A wannan yanayin, display part of the multimeter yana bincika value na resistance.

Diode Check Tare Da Digital Multimeter

Don haka, za ku fadada probes zuwa soketin kamar yadda ake yi a bincike tension, bayyana selector switch to point towards diode check position (Figure 1). Sambarta points to be tested with the leads of the probes. Idan multimeter beep out, yana nuna cewa points are shorted, ba haka za a iya bincika resistance from the display.

Continuity Check Tare Da Digital Multimeter

Continuity check an amfani da shi don bincike cewa akwai low resistance path via two points, saboda haka don bincike cewa points are short or not. Don in iya haka, probes zuwa soketin kamar yadda ake yi a bincike tension, selector switch is made to point towards continuity check position (Figure 1). Sambarta points to be tested with the leads of the probes. Idan multimeter beep out, yana nuna cewa points are shorted, ba haka za a iya bincika resistance from the display.
