Yadda ake amfani da Multimeter na Fieldpiece
Wannan labarin zai koya muku yadda ake amfani da multimeter filin.
A matsayina na ɗan kwangila, Na fi amfani da na'urorin multimeters na Fieldpiece don ayyukana, don haka ina da ƴan shawarwari da zan raba. Kuna iya auna halin yanzu, juriya, ƙarfin lantarki, ƙarfin aiki, mita, ci gaba da zafin jiki.
Yi karatu tare da ku yayin da nake tafiya tare da ku ta cikakken jagora na.
Sassan filin multimeter
- RMS mara igiyar waya
- Gwajin gubar
- Alligator Clamps
- Thermocouple irin K
- Velcro
- alkaline baturi
- Launin taushi mai karewa
Yadda ake amfani da Multimeter na Fieldpiece
1. Gwajin lantarki
- Haɗa jagorar gwajin zuwa masu haɗawa. Dole ne ku haɗa baƙar fata zuwa jack ɗin "COM" da jajayen gubar zuwa jack "+".
- Saita bugun kira zuwa yanayin VDC don duba wutar lantarkin DC akan allunan kewayawa. (1)
- Nuna kuma taɓa masu binciken zuwa wuraren gwajin.
- Karanta ma'auni.
2. Yin amfani da multimeter na Fieldpiece don auna zafin jiki
- Cire haɗin wayoyi kuma matsar da maɓallin TEMP zuwa dama.
- Saka nau'in thermocouple na nau'in K kai tsaye cikin ramukan rectangular.
- Taɓa ƙarshen gwajin zafin jiki (nau'in K thermocouple) kai tsaye zuwa abubuwan gwajin.
- Karanta sakamakon.
Matsakaicin sanyi na mita yana tabbatar da ingantattun ma'auni koda lokacin da yanayin zafin yanayi ya yi yawa.
3. Amfani da wutar lantarki mara lamba (NCV)
Kuna iya gwada 24VAC daga ma'aunin zafi da sanyio ko wutar lantarki mai rai har zuwa 600VAC tare da NCV. Koyaushe bincika sanannen tushen kai tsaye kafin amfani. Jadawalin sashi zai nuna kasancewar ƙarfin lantarki da LED LED. Yayin da ƙarfin filin yana ƙaruwa, ƙarar sautin yana canzawa daga tsaka-tsaki zuwa dindindin.
4. Yin Gwajin Ci gaba tare da Multimeter Fieldpiece
Multimeter filin HVAC kuma kayan aiki ne mai kyau don ci gaba da gwadawa. Ga yadda za ku iya:
- Kashe fis. Kuna buƙatar cire lever kawai don kashe wutar lantarki.
- Ɗauki multimeter filin kuma saita shi zuwa yanayin ci gaba.
- Taɓa na'urorin multimeter zuwa kowane tip ɗin fiusi.
- Idan fis ɗin ku ba shi da ci gaba, zai yi ƙara. Alhali, DMM za ta ƙi yin ƙara idan akwai ci gaba a cikin fis ɗin ku.
5. Duba bambancin ƙarfin lantarki tare da multimeter filin.
Ƙarfin wutar lantarki na iya zama haɗari. Don haka, yana da kyau a bincika fis ɗin ku kuma ganin ko yana can. Yanzu ɗauki filin multimeter kuma bi umarnin da ke ƙasa:
- Kunna fuse; tabbatar yana da rai.
- Ɗauki multimeter na filin kuma saita shi zuwa yanayin voltmeter (VDC).
- Sanya jagororin multimeter akan kowane ƙarshen fuse.
- Karanta sakamakon. Zai nuna sifili volts idan babu bambancin ƙarfin lantarki a cikin fius ɗin ku.

Menene fasalin filin multimeter?
- Lokacin auna ƙarfin lantarki sama da 16 VAC. DC / 35 V A halin yanzu, za ku lura cewa LED mai haske da siginar sauti za su yi ƙararrawa. Wannan gargadin wuce gona da iri ne.
- Saita gripper zuwa matsayi na NCV (ba lambar sadarwa ba) kuma nuna shi a yuwuwar tushen wutar lantarki. Don tabbatar da cewa tushen yana "zafi", kalli LED mai haske na RED da ƙararrawa.
- Thermocouple baya haɗawa bayan ɗan gajeren lokaci na auna wutar lantarki saboda canjin yanayin zafi.
- Ya haɗa da fasalin ceton wutar lantarki da ake kira APO (Auto Power Off). Bayan mintuna 30 na rashin aiki, za ta kashe ta atomatik. An riga an kunna ta ta tsohuwa kuma APO kuma zai bayyana akan allon.
Menene alamun LED ke nunawa?
High ƙarfin lantarki LED - Za ku iya samunsa a gefen hagu kuma zai yi sauti da haske lokacin da kuka duba babban ƙarfin lantarki. (2)
Ci gaba LED - Kuna iya samun shi a gefen dama kuma zai yi sauti da haske lokacin da kuka duba ci gaba.
Alamar wutar lantarki mara lamba - Kuna iya samun shi a tsakiya kuma zai yi ƙara kuma yana haskakawa lokacin da kuke amfani da aikin auna wutar lantarki mara lamba.
Menene ya kamata a yi la'akari lokacin amfani da multimeter filin?
Ga 'yan abubuwan da za ku yi la'akari yayin amfani da multimeter na filin:
– Lokacin aunawa, kar a taɓa buɗaɗɗen bututun ƙarfe, kwasfa, kayan aiki da sauran abubuwa.
– Kafin buɗe mahalli, cire haɗin hanyoyin gwajin.
- Bincika jagorar gwajin don lalacewar rufi ko wayoyi da aka fallasa. Idan haka ne, maye gurbinsa.
– Yayin aunawa, riƙe yatsan hannunka a bayan mai gadin yatsa akan binciken.
– Idan zai yiwu, gwada da hannu ɗaya. Babban ƙarfin wutar lantarki na iya lalata mita har abada.
-Kada a taɓa amfani da na'urori masu yawa na filin yayin hadari.
- Kada ku wuce ƙimar matsawa na 400 A AC yayin auna babban mitar AC halin yanzu. Mitar matsewa ta RMS na iya yin zafi mara jurewa idan ba ka bi umarnin ba.
- Juya bugun kira zuwa matsayin KASHE, cire haɗin gwajin gwajin kuma cire murfin baturin lokacin maye gurbin baturin.
Dubi wasu labaran mu a kasa.
