Maitiro ekushandisa iyo Fieldpiece multimeter

18.02.2023 /

Ichi chinyorwa chinokudzidzisa maitiro ekushandisa munda multimeter.

Semugadziri, ndakanyanya kushandisa Fieldpiece multimeters kumapurojekiti angu, saka ndine matipi mashoma ekugovera. Unogona kuyera zvazvino, kuramba, voltage, capacitance, frequency, kuenderera uye tembiricha.

Verenga pamwe pandinofamba newe kuburikidza negwara rangu rakadzama.

Zvikamu zvemunda multimeter

  • RMS isina waya pliers
  • Test lead kit
  • Alligator Clamps
  • Thermocouple mhando K
  • Velcro
  • alkaline bhatiri
  • Protective soft case

Maitiro ekushandisa iyo Fieldpiece multimeter

1. Kuedza kwemagetsi

  1. Batanidza bvunzo inotungamira kune vanobatanidza. Iwe unofanirwa kubatanidza iyo nhema inotungamira kune "COM" jack uye iyo tsvuku inotungamira kune "+" jack.
  2. Seta dial kuVDC modhi yekutarisa iyo DC voltage pamabhodhi edunhu. (1)
  3. Nongedza uye ubate maprobe kumatest terminals.
  4. Verenga zviyero.

2. Kushandisa Fieldpiece multimeter kuyera tembiricha

  1. Bvisa waya uye fambisa switch yeTEMP kurudyi.
  2. Isa iyo Type K thermocouple yakananga mumakomba ane rectangular.
  3. Bata muromo wetembiricha probes (mhando K thermocouple) zvakananga kune zvinhu zvekuyedzwa. 
  4. Verenga zvabuda.

Iko kutonhora kwemamita kunovimbisa kuyerwa kwakaringana kunyangwe tembiricha iri kuchinjika zvakanyanya.

3. Kushandiswa kweiyo isiri-contact voltage (NCV)

Unogona kuyedza 24VAC kubva kune thermostat kana mhenyu voltage kusvika 600VAC neNCV. Gara uchitarisa nzvimbo inozivikanwa inorarama usati washandisa. Chikamu chegirafu chinoratidza kuvepo kwevoltage uye RED LED. Sezvo simba remumunda richiwedzera, inzwi guru rinoshanduka kubva pakati pepakati kuenda kune rinogara.

4. Kuita Muedzo Wekuenderera mberi neFielpiece Multimeter

Iyo HVAC munda multimeter zvakare chishandiso chakanakira kuyedza kuenderera. Heino maitiro aungazviita:

  • Dzima fuse. Iwe unongoda kudonhedza pasi lever kuti udzime simba.
  • Tora munda multimeter uye uise kune inoenderera modhi.
  • Bata iyo multimeter probes kune yega fuse tip.
  • Kana fuse yako isina kuenderera, inorira. Nepo, iyo DMM inoramba kuridza bhipi kana paine kuenderera mu fuse yako.

5. Tarisa kusiyana kwemagetsi nemunda multimeter.

Kuwedzera kwemagetsi kunogona kuva nengozi. Saka nekudaro, zvakakodzera kutarisa fuse yako uye kuona kana iripo. Zvino tora munda multimeter uye tevera mirairo iri pasi apa:

  • Batidza fuse; ita chokwadi kuti imhenyu.
  • Tora munda multimeter uye uise kune voltmeter (VDC) maitiro.
  • Isa multimeter inotungamira kune imwe neimwe magumo efuse.
  • Verenga zvabuda. Icharatidza zero volts kana pasina mutsauko wemagetsi mu fuse yako.

Inowanzobvunzwa Mibvunzo

Ndezvipi zvinhu zvemunda multimeter?

- Pakuyera ma voltages anopfuura 16 VAC. DC/35 V DC ikozvino, iwe uchaona kuti chiedza che LED uye chiratidzo chinonzwika chicharidza alarm. Iyi inyevero ye overvoltage.

-Seta iyo gripper kune iyo NCV (isina-yekubata voltage) chinzvimbo uye inonongedza pane ingangoita voltage sosi. Kuti uve nechokwadi chekuti kwakabva "kupisa", tarisa iyo inopenya RED LED uye beep.

- Iyo thermocouple haibatanidzi mushure menguva pfupi yekuyera voltage nekuda kweiyo tembiricha switch.

-Inosanganisira chinhu chekuchengetedza simba chinonzi APO (Auto Power Off). Mushure memaminitsi makumi matatu ekusaita, inodzima mita yako. Iyo yatove yakagoneswa nekusarudzika uye APO ichaonekwawo pachiratidziri.

Chii chinonzi LED zviratidzo?

High voltage LED -Unogona kuiwana parutivi rwekuruboshwe uye inorira nekuvhenekera paunenge uchitsvaga yakakwira voltage. (2)

Kuenderera mberi LED - Unogona kuiwana kudivi rekurudyi uye inorira nekuvheneka kana iwe uchinge watarisa kuenderera.

Non-contact voltage indicator -Unogona kuiwana pakati uye inorira nekuvheneka kana iwe ukashandisa iyo yemunda chiridzwa isiri-yekubata voltage kuyerwa basa.

Chii chinofanira kutariswa kana uchishandisa munda multimeter?

Hezvino zvinhu zvishoma zvekufunga kana uchishandisa munda multimeter:

- Panguva yezviyero, usabata akavhurika mapaipi esimbi, zvigadziko, mafittings uye zvimwe zvinhu.

- Usati wavhura imba, bvisa nzira dzekuyedza.

- Tarisa bvunzo inotungamira yekukuvara kwekudzivirira kana waya dzakafumurwa. Kana zvirizvo, chinja.

- Panguva yezviyero, bata zvigunwe zvako kuseri kwechigunwe chinorinda pane probes.

- Kana zvichiita, edza neruoko rumwe. High voltage transients inogona kukuvadza zvachose mita.

- Usambo shandisa munda multimeter panguva yekutinhira.

-Usapfuure iyo clamp rating ye400 A AC kana uchiyera yakakwira frequency AC ikozvino. Iyo RMS clamp mita inogona kupisa zvisingaite kana ukasatevedzera mirairo.

-Nyoresa dhiya ku OFF chinzvimbo, bvisa nhanho dzekuyedza uye sunungura chivharo chebhatiri kana uchitsiva bhatiri.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.

  • CAT multimeter chiyero
  • Multimeter kuenderera chiratidzo
  • Kutarisisa kweiyo Power Probe multimeter
