I-Fluke Multimeter Engcono Kakhulu | Umlingani Oyisibopho Osebenza Ngogesi

Kungakhathaliseki ukuthi udinga ukuhlola isiyingi esincane noma uxhumano olusuka kokulula kuya kusethi eyinkimbinkimbi yezingxenye zikagesi, ama-multimeters ayasiza futhi asebenza njengomoya. Emkhakheni kagesi, i-multimeter iyithuluzi elilodwa lenhloso yonke labaqhubi. Kungakhathaliseki ukuthi kuthatha i-voltage, ukufunda kwamanje noma ukumelana, i-multimeter ikhona ukuze kuthuthukiswe ikhwalithi ezivivinyweni.

I-Fluke igama lomkhiqizo ongenakuqhathaniswa wokuqinisekisa okhiqiza ama-multimeter ekhwalithi. Uma uzimisele ngokuthenga i-multimeter, kungenzeka ukuthi uzogcina ubambe i-multimeter ye-Fluke ehamba phambili. Silapha ukuze sikuqondise kuzo zonke izinyathelo.

Umhlahlandlela wokuthenga we-Fluke Multimeter

Ama-multimeter kaFluke enza ubulungiswa egameni lawo. Kodwa ukwazi ngezici ezifanele ezifanele isidingo sakho kungaba nzima. Lapha silungise izici okudingeka uzicabangele ngaphambi kokuthenga i-multimeter. Landela futhi ngeke udinge ukuthi ushaye ikhanda kamuva.

Ukulinganisa Ukuhlukahluka

I-multimeter kufanele ikwazi ukwenza imisebenzi eyisisekelo efana ne-voltage, isilinganiso samanje nokumelana. Kufanele uqiniseke ukuthi i-multimeter yakho iyakwazi okungenani le misebenzi emithathu. Ngaphezu kwalokhu, ukuhlolwa kwe-diode, ukuhlolwa kokuqhubeka, ukukalwa kwezinga lokushisa, njll kwenza i-multimeter ehloniphekile.

Ububanzi Bokulinganisa

Kanye nemisebenzi ehlukene yokulinganisa, ububanzi bubuye bube yindaba ebalulekile yokuzikhethela. Kufanele uqiniseke ukuthi i-multimeter yakho iyakwazi ukukala okungenani i-voltage engu-20mA yamanje kanye ne-50mV. Ibanga eliphezulu lingu-20A kanye ne-1000V ngokulandelanayo. Ngokuqondene nokumelana, kufanele ikwazi ukukala i-3-4 MΩ.

Ububanzi buncike ngokuphelele emkhakheni wakho womsebenzi. Nakuba ububanzi bubanzi, bungcono.

Uhlobo Lokunikezwa

Kungaba ukunikezwa kwe-AC noma kwe-DC, i-multimeter kufanele ikwazi ukunikeza ukufundwa kuzo zombili izimo. I-multimeter yedijithali iyakwazi ukuhlola ukuthi umthwalo uyi-AC noma i-DC. Lokhu kuphakathi kwezici eziyisisekelo i-multimeter engamboza.

I-Backlight futhi Ubambe Umsebenzi

Izibani zangemuva ze-LCD zikwenza ukwazi ukufunda ezimeni eziphansi zokukhanya. Endabeni yama-multimeters, i-backlight ehloniphekile ivumela ukuthi iguquguquke futhi ifundeke kusuka kuma-engeli ahlukene. Kuyisici esibalulekile okudingeka usicabangele uma umsebenzi wakho ubandakanya ukuxazulula izinkinga zezimboni noma ukusebenza kukagesi osindayo.

Ngakolunye uhlangothi, umsebenzi wokubamba ikuvumela ukuthi usethe indawo eyireferensi ukuze uyiqhathanise nokufundwayo okulandelayo. Ngamanye amazwi, lo msebenzi uthwebula isilinganiso esimisiwe ukuze usifinyelele.

Ukufakwa Kokufaka

Abantu abaningi abasinaki lesi sici, kodwa akufanele. I-impedance engaphandle kobubanzi ingabangela isekethe ukuthi ibhale phezu kwe-impedance yonke inciphisa ukumelana futhi ibangele izinkinga ezinkulu. Kufanele uqiniseke ukuthi i-multimeter oyithengayo ine-impedance yokufaka okungenani engu-10MΩ.

Resolution

Ukulungiswa kubhekiselwa ekubalweni kwesibonisi noma isamba senani lamadijithi angaboniswa esibukweni. Ukuphakama kwenani lezibalo, kungcono. Ama-multimeter ahlukahlukene kakhulu ngokuvamile anesibalo sokubonisa esingu-4000-6000. Uma isibalo singu-5000, isibonisi singase sikubonise i-voltage engu-4999.

Ukulungiswa okungcono kwesibonisi kwenza kube lula kuwe ukuthi uhlole ngokucophelela futhi kunikeze okukhiphayo okungcono.

Ukufundwa kwe-RMS kwangempela

Ama-multimeter eqiniso e-RMS angakwazi ukufunda kokubili i-AC noma i-DC voltage kanye neyamanje. Ukubaluleka kwe-multimeter ye-RMS kuyenzeka ngempela uma umthwalo ungekho emgqeni. Lesi sici senza i-multimeter ikwazi ukufunda ama-spikes noma ukuhlanekezela kanye nesilinganiso esinembile samanje kanye ne-voltage. Amadrayivu ezimoto, izintambo zikagesi, i-HVAC (ukushisisa, ukungena komoya nomoya), njll kudinga ukufundwa kwe-RMS yangempela.

Ukuphepha

Ukuphepha kwe-multimeter kukalwe izilinganiso ze-CAT. Izigaba zeCAT ziza ngezinhlobo ezi-4: I, II, III, IV. Ukuphakama kwesigaba, ukuvikela okuphezulu okukunikezayo. Iningi lama-multimeters e-Fluke yi-CAT III 600V noma i-CAT IV 1000V elinganiselwe. Inombolo ye-voltage ngokuyisisekelo imele isilinganiso sokumelana nesikhashana. Ukuphakama kwamandla kagesi esigabeni esifanayo, kuphephe kakhudlwana ukusebenza.

Kufanele ukhethe imitha enesilinganiso esilungile se-CAT esifanele indawo ozoyisebenzisa kuyo.

Iwaranti

Amanye ama-multimeter e-Fluke anezici zewaranti yempilo yonke. Kuzo zonke ezinye, iwaranti yeminyaka embalwa inikezwa. Kuhlale kuphephile ukubheka izipesheli zewaranti njengoba umkhiqizo owu-odayo ungase ubhekane nokungasebenzi kahle ekuqaleni ongakwazi ukukuphikisa njalo uma unekhadi lesiqinisekiso.

I-Best Fluke Multimeters ibuyekeziwe
