Ungayisebenzisa kanjani i-Fieldpiece multimeter

Lesi sihloko sizokufundisa indlela yokusebenzisa i-multimeter yasensimini.

Njengosonkontileka, ngisebenzise ikakhulukazi ama-multimeter e-Fieldpiece kumaphrojekthi ami, ngakho-ke nginamathiphu ambalwa engingawabelana ngawo. Ungakwazi ukukala okwamanje, ukumelana, i-voltage, amandla, imvamisa, ukuqhubeka kanye nezinga lokushisa.

Funda njengoba ngihamba nawe ngomhlahlandlela wami onemininingwane.

Izingxenye ze-multimeter yenkundla

• Amapulangwe angenantambo e-RMS
• Ikhithi yokuhola yokuhlola
• I-Alligator Clamps
• Uhlobo lwe-thermocouple K
• I-Velcro
• ibhethri ye-alkaline
• Ikesi elithambile elivikelayo

Indlela yokusebenzisa i-Fieldpiece multimeter

1. Ukuhlolwa kukagesi

1. Xhuma imikhondo yokuhlola kuzixhumi. Kumelwe uxhume intambo emnyama kujekhi ethi "COM" kanye nomthofu obomvu kujeke "+".
2. Setha ukudayela kumodi ye-VDC ukuze uhlole amandla kagesi e-DC kumabhodi wesekethe. (1)
3. Khomba futhi uthinte ama-probe kumatheminali okuhlola.
4. Funda izilinganiso.

2. Ukusebenzisa i-Fieldpiece multimeter ukukala izinga lokushisa

1. Nqamula izintambo bese uhambisa iswishi ye-TEMP kwesokudla.
2. Faka uhlobo lwe-thermocouple yohlobo K ngqo emigodini engunxande.
3. Thinta ichopho lezinga lokushisa (thayipha K thermocouple) ngokuqondile ezintweni zokuhlola. 
4. Funda imiphumela.

Ukuhlangana okubandayo kwemitha kuqinisekisa izilinganiso ezinembile ngisho nalapho izinga lokushisa le-ambient lishintshashintsha kakhulu.

3. Ukusetshenziswa kwamandla kagesi angathinteki (NCV)

Ungahlola i-24VAC kusukela ku-thermostat noma i-voltage ebukhoma ifike ku-600VAC nge-NCV. Njalo hlola umthombo obukhoma owaziwayo ngaphambi kokuwusebenzisa. Igrafu yengxenye izobonisa ukuba khona kwamandla kagesi kanye ne-LED RED. Njengoba amandla enkundla ekhula, ithoni ephezulu iyashintsha ukusuka kokuphakathi ukuya kokuqhubekayo.

4. Ukwenza Ukuhlolwa Okuqhubekayo nge-Fieldpiece Multimeter

I-multimeter yenkundla ye-HVAC nayo iyithuluzi elikahle lokuhlola ukuqhubeka. Nansi indlela ongakwenza ngayo:

• Vala i-fuse. Udinga kuphela ukudonsa phansi i-lever ukuze ucime amandla.
• Thatha i-multimeter yenkundla bese usetha kumodi eqhubekayo.
• Thinta ama-multimeter probe kuthiphu ye-fuse ngayinye.
• Uma i-fuse yakho ingenakho ukuqhubeka, izokhala. Nakuba, i-DMM izonqaba ukukhala uma kukhona ukuqhubeka ku-fuse yakho.

5. Hlola umehluko we-voltage nge-multimeter yenkundla.

Ukwenyuka kwamandla kungaba yingozi. Ngakho-ke, kufanelekile ukuhlola i-fuse yakho futhi ubone ukuthi ikhona yini. Manje thatha i-multimeter yensimu bese ulandela imiyalo engezansi:

• Vula i-fuse; qiniseka ukuthi iyaphila.
• Thatha i-multimeter yenkundla bese usetha kumodi ye-voltmeter (VDC).
• Beka imikhondo ye-multimeter ekugcineni kwefuse.
• Funda imiphumela. Izobonisa ama-volts anguziro uma ungekho umehluko we-voltage ku-fuse yakho.

Imibuzo evame ukubuzwa

Yiziphi izici ze-multimeter yasendle?

- Uma ukala ama-voltage angaphezu kuka-16 VAC. DC/35 V DC okwamanje, uzoqaphela ukuthi i-LED ekhanyayo nesignali ezwakalayo izokhala i-alamu. Lesi yisixwayiso se-overvoltage.

- Setha into yokubamba endaweni ye-NCV (i-voltage engeyona ethintwayo) bese uyikhomba emthonjeni we-voltage okungenzeka ube nawo. Ukuqinisekisa ukuthi umthombo "uyashisa", bukela i-LED ebomvu ekhanyayo kanye nebhiphu.

- I-thermocouple ayixhumi ngemva kwesikhathi esifushane sokulinganisa i-voltage ngenxa yokushintsha kwezinga lokushisa.

- Kuhlanganisa isici sokulondoloza amandla esibizwa nge-APO (Auto Power Off). Ngemuva kwemizuzu engama-30 yokungasebenzi, izocisha imitha yakho ngokuzenzakalelayo. Isivele inikwe amandla ngokuzenzakalela futhi i-APO izovela esikrinini.

Izinkomba ze-LED zikhombisani?

I-LED ye-voltage ephezulu - Ungayithola ngakwesokunxele futhi izokhala futhi ikhanyise lapho uhlola amandla kagesi aphezulu. (2)

Ukuqhubeka kwe-LED - Ungayithola ngakwesokudla futhi izokhala futhi ikhanyise uma uhlola ukuqhubeka.

Inkomba ye-voltage engaxhunywanga – Ungayithola phakathi nendawo futhi izokhala futhi ikhanyise uma usebenzisa umsebenzi wokulinganisa ugesi ongathinteki wensimbi.

Yini okufanele icatshangelwe lapho usebenzisa i-multimeter yensimu?

Nazi izinto ezimbalwa okufanele uzicabangele lapho usebenzisa i-multimeter yasendle:

- Ngesikhathi sokulinganisa, ungathinti amapayipi ensimbi avulekile, amasokhethi, okokufaka nezinye izinto.

- Ngaphambi kokuvula izindlu, nqamula imikhondo yokuhlola.

– Hlola imikhondo yokuhlola ukuthi ayinamonakalo yini noma izintambo ezivelile. Uma ikhona, yishintshe.

- Ngesikhathi sokulinganisa, bamba iminwe yakho ngemuva kwesigadi somunwe kuma-probes.

– Uma kungenzeka, hlola ngesandla esisodwa. Ama-voltage aphezulu angalimaza unomphela imitha.

- Ungalokothi usebenzise ama-multimeter ensimini ngesikhathi sokuduma kwezulu.

- Ungadluli isilinganiso se-clamp engu-400 A AC lapho ukala imvamisa ephezulu ye-AC yamanje. I-RMS clamp meter ingashisa ngokungabekezeleleki uma ungayilandeli imiyalelo.

– Vala ukudayela, nqamula imikhondo yokuhlola futhi ukhulule ikhava yebhethri lapho ushintsha ibhethri.
