Gabatarwa

Wannan jagorar tana ba da cikakken bita da kuma gwajin tafiya na Deek-Robot DC 0-100V 10A dijital voltmeter, ammeter, da wattmeter. Wannan kayan aiki ne mai amfani, duka-duka panel mita wanda ke ba ka damar lura da halayen lantarki na DC circuit a lokaci guda. Kayan aiki ne mai muhimmanci ga kowane benci na lantarki, aikin maker, ko saitin wutar lantarki na DIY.

Babban nunin dijital na module yana nuna ma'auni uku masu muhimmanci a lokaci guda: wutar lantarki (voltage), halin yanzu (current), da kuma ƙididdigar ƙarfi (a watts). Wannan yana sa ya zama mai matukar dacewa don gano matsala, lura da aiki, da kuma tabbatar da cewa circuits ɗinka suna aiki cikin iyakokin aminci. Ana samun mita a cikin nau'ikan daban-daban (misali, 5A/50V ko 10A/100V) don dacewa da kewayon aikace-aikace.

Ga wasu hanyoyi masu amfani da za ka iya amfani da wannan mita a cikin ayyukanka:

• Lura da Bench Power Supply: Ƙara shi zuwa wutar lantarki mai canzawa don sanin ainihin wutar lantarki da halin yanzu da ake bayarwa ga circuit ɗinka.
• Gwajin Fitar da Baturi: Lura da wutar lantarki da halin yanzu na baturi a ƙarƙashin nauyi don kimanta matakin caji da lafiyarsa.
• Fitar da Solar Panel: Tabbatar da ainihin ƙarfin fitarwa na ƙaramin solar panel don tabbatar da cewa yana aiki yadda ya kamata.
• Halin Yanzu na Motor: Duba yawan amfani da wutar lantarki na DC motors don gano idan suna tsayawa ko yin aiki fiye da kima.
• DIY Power Bank ko Charger: Haɗa shi cikin charger na al'ada don nuna wutar lantarki da halin yanzu na caji.
• Gano Matsalar Circuits: Gano da sauri idan circuit yana jan wutar lantarki da yawa, wanda zai iya nuna gajeren kewayawa ko gazawar kayan aiki.

Bayanin Hardware

Wannan mita an tsara shi don sauƙi da sauƙin amfani. Yana da babban LCD mai haske mai haske, yana sa karatun ya kasance mai sauƙin gani ko da a wurare masu duhu. Wani fasali na musamman shine samun damar kai tsaye zuwa calibration potentiometers a gaban naúrar, yana ba da damar daidaitawa cikin sauri da sauƙi na duka karatun wutar lantarki da halin yanzu ba tare da wani rushewa ba.

Module yana cikin ƙaramin akwati mai ɗauke da clip, wanda aka tsara don amintaccen shigarwa a cikin yankin panel. Girman jiki kamar haka:

• Tsawon Module: 79.3 mm
• Faɗin Module: 42.8 mm
• Faɗin Yankin Panel: 39.1 mm
• Tsawon Yankin Panel: 71.4 mm
• Zurfin Module (ciki har da connector): 41.8 mm
• Nauyi: 32.5 grams

Lokacin tsara panel ɗinka, dole ne ka yi la'akari da aƙalla 30 mm na sarari a bayan module don ɗaukar connector da wayoyi.

Jagorar Wayoyi

Fahimtar wayoyi yana da muhimmanci ga daidaitaccen aiki. Wannan mita yana buƙatar keɓaɓɓen wutar lantarki don sarrafa kayan aikin ciki. Wannan ƙira ce ta gama gari ga irin waɗannan mitoci don tabbatar da cewa daidaiton auna ba ya shafar circuit ɗin da ake gwadawa.

Wutar Lantarki (7-12V DC): Mita yana buƙatar nasa tushen wutar lantarki. Haɗa wutar lantarki ta 7V zuwa 12V DC zuwa wayoyi biyu masu sirara (yawanci ja da baƙi). Wannan yana sarrafa nuni da kuma dabaru na auna.

Auna Wutar Lantarki: Don auna wutar lantarki na babban circuit ɗinka, za ka haɗa waya ta uku mai sirara (sau da yawa fari ko kore) kai tsaye zuwa madaidaicin terminal na tushen wutar da kake aunawa. Wannan haɗi ne mai girma wanda kawai yake jin wutar lantarki kuma yana jan ƙaramin halin yanzu.

Auna Halin Yanzu: Ana yin wannan ta amfani da wayoyi biyu masu kauri. Halin yanzu dole ne ya gudana ta cikin mita. Dole ne a karya circuit, kuma a saka mita a jere. Madaidaicin terminal na tushen wutar ka yana haɗawa da waya ɗaya mai kauri. Halin yanzu yana gudana ta cikin shunt resistor na ciki kuma ya fita daga ɗayan waya mai kauri, wanda sai ya haɗa zuwa madaidaicin terminal na kayan aikin ka. Ƙarƙashin gefen circuit an haɗa shi kai tsaye daga tushen wutar zuwa kayan aiki.

Ga hanya mai sauƙi don ganin hanyar halin yanzu:

1. Tushen Wutar (+) → Waya Mai Kauri ta Mita (In)
2. Waya Mai Kauri ta Mita (Out) → Kayan Aiki (+)
3. Kayan Aiki (-) → Tushen Wutar (-)

Rashin wutar lantarki a cikin shunt resistor na mita yana da ƙanƙanta (kusan 48mV a 10A), don haka yana da ƙaramin tasiri a kan aikin circuit ɗinka.

Da fatan za a koma ga zanen wayoyi da ke ƙasa don nunin gani na waɗannan haɗin.

Rayayyun Nunawa da Gwaji

A cikin bidiyon, an gwada mita ta jerin gwaje-gwaje don tabbatar da daidaito da aikin sa.

Auna Ƙarfi: An haɗa mita ɗin zuwa na'urar lantarki don gwada lissafin ƙarfinsa. Tare da ci gaba na yanzu na 2.36A, an nuna ƙarfin daidai kamar 34.2W. Lokacin da aka ƙara wutar lantarki, karatun ƙarfin ya ƙaru daidai gwargwado, yana tabbatar da lissafin P = V × I. Mita ɗin ya nuna karatun ƙarfi daidai har zuwa iyakar mafi girma na 1000W.

Auna Yanzu: An gwada mita ɗin tare da nau'ikan ci na yanzu. An tabbatar da cewa yana da inganci sosai a iyakar rated na yanzu na 10A. Gwajin ya nuna cewa mita ɗin ba zai nuna ƙimar da ta wuce iyakar 10A ba, ko da an tilasta ƙarin yanzu ta cikinsa. A 15A, nunin ya kasance a 11A, yana nuna cewa na'urar firikwensin ciki an iyakance shi a iyakar ƙirarsa.

Daidaita Wutar Lantarki: Bidiyon yana nuna yadda ake daidaita karatun wutar lantarki. Ta hanyar haɗa tushen wutar lantarki da aka sani, daidai (21.4V a gwajin) zuwa mita ɗin da daidaita potentiometer na wutar lantarki, ana iya daidaita nunin don dacewa da karatun tunani daidai.

Faduwar Wutar Lantarki ta Shunt Resistor: Ma'auni mai mahimmanci shine faduwar wutar lantarki a cikin shunt resistor na ciki. Tare da 10A na yanzu da ke gudana, an auna faduwar a ƙaramin 48 millivolts (mV). Wannan yana da kyau sosai kuma yana tabbatar da ƙarancin asarar ƙarfi a hanyar auna. Ana iya amfani da wannan ƙimar don lissafin juriya na shunt ta amfani da Dokar Ohm (R = V/I), wanda ke samar da 0.048V / 10A = 0.0048Ω, ko 4.8 milliohms.

Ƙarshe

Mita ƙarfin Deek-Robot DC 0-100V 10A na'ura ce da ake ba da shawarar sosai, daidai, kuma mai sauƙin amfani. Babban nuninsa mai haske da sauƙin wayoyi sun sa ya zama ƙari mai kyau ga kowane aikin lantarki. Potentiometers na daidaitawa kai tsaye suna da fa'ida mai mahimmanci, suna sauƙaƙa tabbatar da daidaitattun karatu. Ko kai mai sha'awa ne ko ƙwararre, wannan mita kayan aiki ne mai aminci da mahimmanci don kula da ƙarfin DC.
