Momwe mungagwiritsire ntchito Multimeter Fieldpiece

18.02.2023 /

Nkhaniyi ikuphunzitsani momwe mungagwiritsire ntchito multimeter yam'munda.

Monga kontrakitala, ndagwiritsa ntchito ma multimeter a Fieldpiece pama projekiti anga, kotero ndili ndi malangizo ochepa oti ndigawane. Mutha kuyeza pano, kukana, voteji, capacitance, ma frequency, kupitiliza ndi kutentha.

Werengani pamodzi ndikuyenda nanu kudzera mu kalozera wanga watsatanetsatane.

Zigawo za multimeter yamunda

  • RMS opanda zingwe
  • Mayeso otsogolera zida
  • Chingwe cha Alligator
  • Thermocouple mtundu K
  • Velcro
  • batire ya alkaline
  • Chotetezera chofewa

Momwe mungagwiritsire ntchito Multimeter Fieldpiece

1. Kuyesa kwamagetsi

  1. Gwirizanitsani zoyeserera ku zolumikizira. Muyenera kulumikiza chiwongolero chakuda ku jack ya "COM" ndikuwongolera kofiira ku jack "+".
  2. Khazikitsani kuyimba kwa VDC kuti muwone mphamvu ya DC pama board ozungulira. (1)
  3. Lozani ndi kukhudza ma probe kupita kumalo oyesera.
  4. Werengani miyeso.

2. Kugwiritsa ntchito multimeter ya Fieldpiece kuyeza kutentha

  1. Lumikizani mawaya ndikusuntha chosinthira cha TEMP kumanja.
  2. Ikani thermocouple ya Type K molunjika mumabowo amakona anayi.
  3. Gwirani nsonga ya zoyezera kutentha (mtundu wa K thermocouple) molunjika kuzinthu zomwe zikuyenera kuyesedwa. 
  4. Werengani zotsatira.

Mphambano wozizira wa mita umatsimikizira miyeso yolondola ngakhale kutentha komwe kumasinthasintha kumasinthasintha.

3. Kugwiritsa ntchito magetsi osalumikizana (NCV)

Mutha kuyesa 24VAC kuchokera pa thermostat kapena voteji yamoyo mpaka 600VAC ndi NCV. Nthawi zonse fufuzani malo odziwika omwe alipo musanagwiritse ntchito. Gawo la graph likuwonetsa kupezeka kwa magetsi ndi LED YOFIIRA. Pamene mphamvu ya m'munda ikuwonjezeka, kamvekedwe kake kamasintha kuchoka pakatikati mpaka kusinthasintha.

4. Kuchita Mayeso Opitirizabe ndi Fieldpiece Multimeter

HVAC field multimeter ndi chida chabwino choyesera kupitiliza. Nayi momwe mungachitire:

  • Zimitsani fusesi. Mukungofunika kugwetsa lever kuti muzimitse mphamvu.
  • Tengani multimeter yam'munda ndikuyiyika kuti ikhale yopitilira.
  • Gwirani ma probe a multimeter pansonga iliyonse ya fusesi.
  • Ngati fusesi yanu ilibe kupitiliza, imalira. Pomwe, DMM ikana kuyimba ngati pali kupitiliza mu fuse yanu.

5. Yang'anani kusiyana kwa magetsi ndi multimeter yamunda.

Kukwera kwamphamvu kungakhale koopsa. Chifukwa chake, ndikofunikira kuyang'ana fusesi yanu ndikuwona ngati ilipo. Tsopano tengani gawo la multimeter ndikutsata malangizo omwe ali pansipa:

  • Yatsani fusesi; onetsetsani kuti ali moyo.
  • Tengani multimeter yamunda ndikuyiyika kukhala voltmeter (VDC) mode.
  • Ikani ma multimeter kumapeto kwa fusesi.
  • Werengani zotsatira. Iwonetsa ziro volts ngati palibe kusiyana kwamagetsi mu fusesi yanu.

Mafunso ofunsidwa kawirikawiri

Kodi mawonekedwe a field multimeter ndi chiyani?

- Mukayesa ma voltages akulu kuposa 16 VAC. DC/35 VDC panopa, mudzawona kuti kuwala kwa LED ndi chizindikiro chomveka chidzamveka alamu. Ili ndi chenjezo la overvoltage.

- Khazikitsani chogwirizira pamalo a NCV (voltage osalumikizana) ndikuchilozera komwe kuli gwero lamagetsi. Kuti muwonetsetse kuti gwero ndi "lotentha", yang'anani kuwala kwa LED RED ndi beep.

- Thermocouple sichimalumikizana pakapita nthawi yochepa ya kuyeza kwamagetsi chifukwa cha kusintha kwa kutentha.

- Zimaphatikizapo gawo lopulumutsa mphamvu lotchedwa APO (Auto Power Off). Pambuyo pa mphindi 30 osagwira ntchito, imangozimitsa mita yanu. Yathandizidwa kale mwachisawawa ndipo APO idzawonekeranso pazenera.

Kodi zizindikiro za LED zikuwonetsa chiyani?

Mphamvu yapamwamba ya LED - Mutha kuyipeza kumanzere ndipo imayimba ndikuwunikira mukamayang'ana magetsi apamwamba. (2)

Kupitilira kwa LED - Mutha kuyipeza kumanja ndipo imayimba ndikuwunikira mukamayang'ana mosalekeza.

Chizindikiro chamagetsi osalumikizana - Mutha kuzipeza pakati ndipo zidzayimba ndikuwunikira mukamagwiritsa ntchito chida chopanda kukhudzana ndi kuyeza voteji.

Zomwe ziyenera kuganiziridwa mukamagwiritsa ntchito multimeter yam'munda?

Nazi zinthu zingapo zomwe muyenera kuziganizira mukamagwiritsa ntchito multimeter yam'munda:

- Pamiyezo, musakhudze mapaipi achitsulo otseguka, zitsulo, zomangira ndi zinthu zina.

- Musanatsegule nyumba, chotsani zowongolera zoyeserera.

- Yang'anani mayendedwe oyeserera kuti muwone kuwonongeka kwa zotchingira kapena mawaya owonekera. Ngati ndi choncho, sinthani.

- Mumiyezo, gwirani zala zanu kumbuyo kwa cholondera chala pama probes.

- Ngati n'kotheka, yesani ndi dzanja limodzi. Ma voliyumu apamwamba amatha kuwononga mita.

- Osagwiritsa ntchito ma multimeter akumunda pakagwa mvula yamkuntho.

- Osapitilira 400 A AC poyesa ma frequency apamwamba a AC. Mamita a RMS amatha kutentha kwambiri ngati simutsatira malangizowo.

- Yatsani kuyimba kuti ZIMIMIRE, chotsani zowongolera ndikumasula chivundikiro cha batri mukamalowetsa batire.

Onani zina mwazolemba zathu pansipa.

  • CAT multimeter mlingo
  • Chizindikiro chopitilira ma multimeter
  • Chidule cha Power Probe multimeter
