[UMarco] wajonga kwiimitha ezininzi. Nangona kunjalo, ucinga ukuba i-HP34588a yeyona ilungileyo, nangona zaziziswa ngaphezulu kweminyaka engama-30 eyadlulayo ngo-1989. Umntu othile unikele i-2 kaMarco], kodwa wabonisa indlela engazinzanga xa iqalile, ngoko ke wayefuna ukulungiswa.
Ngokutsho kwe [Marco], ikhowudi yempazamo ibonisa ingxaki kunye nomguquli we-faepe-to-digital on-digital, eyiyo le nto iyenza i-miter eyahlukileyo. Imitha ineenombolo eziyi-8,5, ke inqanaba eliqhelekileyo lokuguqula aliyi kuyisiki.
Iindaba ezimnandi malunga nalo mbandela kukuba isinika isizathu sokujonga ngaphakathi ebhokisini. Yonke ibhodi yamanye ngaphakathi ijongeka inzima njengebhodi yebhodi ye-PC yanamhlanje. Ngaphakathi kolu luhlu lungendo, iBhodi yeSekethe igubungele inethiwekhi enesifiso esingasebenziyo.
Indlela esemgangathweni yokuguqula i-voltage kwinani elisebenzisa ixesha elifunekayo lokuhlawula kwaye likhuphe i-capacitoti, kwaye ixesha elifunekayo libonisa ivolthi. Imitha isebenzisa uninzi lokuthintela amathambeka, [uMarco] ichaza indlela imitha isebenzisa indlela yokufunda ngokukhawuleza nechanekileyo yokufunda ngokukhawuleza, emva koko isebenzise ithambeka elicothayo kwaye lichanekile.
I-chip yesiko ine-ic kunye nenethiwekhi yesiko. Ukuba iyasilela, imitha iphantse ayinakwenzeka ukuba ilungiswe ngaphandle kweZiko leNkonzo ye-SPRINC lokuthenga iBhodi yeSiphako entsha malunga ne-3,000 yeedola. I-chip yesiko ibonakala ngathi isebenza ngokufanelekileyo, kwaye ithathe indawo eyaziwayo eyaziwayo ukuba ayincedi.
Yintoni elandelayo? Thenga onke amacandelo onokufumana kwiBhodi yeSekethe (malunga ne-100 yeedola), emva koko uthathe indawo yonke. Sithanda indlela yakhe yokukhupha icandelo elingafunekiyo sikhokelela ngexesha lenkqubo yokuphindaphinda. Ekuqaleni, oku kwabonakala kufanelekile, kodwa ukuzilawula akuphumelelanga. Kubonakala ngathi i-IC i-IC isenokuba yaphukile, ngenxa yoko ekugqibeleni wayitshintshe yonke ibhodi eguqulweyo.
Oku kucoca impazamo enkulu, kodwa eminye imilinganiselo isaneengxaki, kubangela enye ibhodi ihlawulwe. Isekethe ekwenzeni i-RMS yokuguqula kwimiqondiso ye-AC. Imitha inezindlela ezahlukeneyo zokulinganisa i-RMS.
Le vidiyo libali elihle lemfundo, kwaye uya kufunda okuninzi malunga neemitha eziphezulu. Xa yonke into iqhelekile, siza kubona ezinye izinto ezingaqhelekanga, ezinjengeentambo ezenza amandla kunye nabalandeli abanengxolo.
Ndikhe ndasebenza nenjineli eyile indawo ye-analog. Watsho ukuba lo ngumzamo omkhulu, kwaye benze umsebenzi omninzi kunokuba babelindele. Ukholelwa oku kuyinxalenye yesizathu sokuba i-HP / Aguag / Aliight / Canight iqalile kodwa soze igqibe inguqulelo yokuphucula. Kuphela yi-floke kuphela ene-DMM enokuthelekiswa, kwaye kunokutshiwo ukuba i-3458 iseyeyona ilungileyo. Kunzima kakhulu ukuvelisa iimveliso ezingcono.
Omnye umntu undixelele ukuba i-AtoVover yeyona nto ibalulekileyo ingathengwa yimali. Iqiniswe kwilitye, awalufumana uMoses entabeni apho uloyiso. Ngokucacileyo ndalahlekiswa.
Kuba i-APOO8 ayiqhelekanga kweli chibi, ndikufumanise ukuba le nto ndiyifundayo ... http://www.irithardsradios.co.html
Ndinqwenela i-pher 8 xa ndandikwishumi elivisayo, kodwa amaxabiso abo ayengaphaya kwamandla am. Kwiminyaka engama-40 kamva, ndine-MK II kwibhentshi yam. Kwimeko engaqhelekanga apho ndisebenza khona kwirediyo ye-valve, ndonwabile ukusebenzisa imitha ngomjikelo ochanekileyo.
Zonke ezi shiphiters zingcono malunga nezinye izilingo ezininzi ukusuka ekungaqondini kwesicelo se-HP3458A. Ayisetyenziselwa ukufumana isimo sengqondo esiqhelekileyo, kodwa kumememo we-semicondcuction, kunye nokuchaneka kwayo kwi-UA kunye ne-UV kuhle kakhulu. Umsebenzi wemilinganiselo ye-4-Wire wire
Ndithenge i-keithy yakudala ye-5.5 ndayilinganisa ngumhlobo. Kunyaka ophelileyo, kufanelekile ngokwenene. Ukusuka ekuguquleni ngokuhambelana nokulinganisa ukufaka igalelo le-AMPIO AMPILIRES.
I-flue 77 isenokuba sisixhobo esihle sendlela, kodwa ayisiyo "eyona nto" ilungileyo "kuyo nayiphi na imeko. Nokuba yeyiphi na iimfuno zakho, i-flue ithengise ngcono: iimoto? I-88v. Imeko yokuqhushumba? I-87V yokuqhuma-ubungqina obuyingozi? I-28 ezimbini. Ishishini ngokubanzi? I-87V. Ingxelo yedatha? 287/289. Ukulawulwa kwenkqubo yemveliso? 789.
Ukongeza kweminye imisebenzi ayinakwenzaka-77 ayinakwenza konke konke, nayiphi na kwezi zixhobo zinokujongana nawo nawuphi na umsebenzi onokuqhubela phambili, ngokuchaneka okuphezulu kunye ne-bandli. Ubushushu? Ukuqhutywa? I-PWM yomjikelo / ububanzi be-pulse? rhoqo? I-microampere? Isantya esijikelezayo? I-VMS YENYANISO YENYANISO? Umnqweno omhle.
Xa ithengisa ngeedola ezingama-300 kwi-Amazon, asikwazi nokuthi i-flue 77 yindlela yohlahlo-lwabiwo mali lwamatewali. Ewe kunjalo, iphantsi kunezinye iimitha ezidwelisiweyo, kodwa oko akuthethi kakhulu. (289 ngoku ukuthengiswa kwabantu abanomdla kwi- $ 570). Inyani yile yokuba ukuba usebenzisa iimitha ukwenza imali, emva koko iflekhi efanelekileyo iya kuzihlawula ngokukhawuleza. Mhlawumbi ufuna kuphela imisebenzi engama-77. Kulungile, thenga i-77.
Into inje. Mhlawumbi abasebenzisi beshishini banokuchaza ngokungqongqo iimfuno zabo zemihla ngemihla. Mhlawumbi inkampani ithumele iingcali ezingama-77s ngaphandle, kwaye isuphavayiza yayiphethe into enokubakho (njenge-87s enama-thermocoupuples) kwiimeko ezinqabileyo ezifuna imilinganiselo yobushushu. Oku kubonakala kuyinto elumkileyo ukunciphisa iindleko eziphezulu, umngcipheko ngenxa yobusela okanye ilahleko, njl njl, kodwa ungaqala ukuphuculwa kweyure oyichithayo kwimitha.
I-Hobbyists ayifane ichazwe ngokungqongqo, kwaye ayinayo isicwangciso sokuhla kwexabiso elinokusetyenziselwa ukukhulula iindleko ngaphezulu kweminyaka eliqela. Ukuba kufuneka sithenge iimitha ezimbini, zihlala zingcono ukuthenga okokuqala okokuqala.
Ngomonde, ekugqibeleni ndafumanisa ukuba i-sleke yam isebenzise i-189 (umphambili we-289) kwi-craigslist ngexabiso le-dist. Kubonakala ngathi ayikaze ishiye ibhokisi yayo kwaye ingaphawulwa ngokupheleleyo. Ingcebiso yam kwezinye iingcali zeHobbynists kukuthenga ezona zinto zinamandla zisebenziseka kakhulu. Inokuba yi-77.
Andisokuze ndiqonde imisebenzi engaphakathi yolu hlobo lwegiya. Ngokucacileyo, wenza, kwaye kwakunomdla kakhulu ukumbopha ukulungisa into abanye abantu abanokuqondwa.
Imitha yam yemihla ngemihla yokuthwala yi-8060, endandiyithenga ngo-1983. Xa i-Simpson 260 yalawula isixhobo se-Tetratic, yayisisixhobo sokutshintsha umdlalo, kwaye i-800a yayiselungile. Ngo-1990, kwafuneka ndithumele i-8060 yam ibuyele kwi-fluke kuba i-chip yomqhubi yaphukile, kodwa emva koko ilungisiwe, bendisebenzisa rhoqo i-800a rhoqo. Ndisandula ukuphinda ndilungelelanise i-keys44461A 6.5 I-6.5 ye-6.5 ye-Benchtop. Ngexesha lokulinganisa kwe-voltage yethutyana, ukuphambuka kwe-flue 8060 ukusuka kwi-34461 kwi-bandwidth yayo yayiphakathi kwe-1%. Oku akulunganga kwimitha ebiyisiwe kwikhithi kangangeminyaka engama-30 oko kuguqulwe kwangaphambili.
Ndine-fluoke i-pleoke 80SMUMTINGINE. Malunga neminyaka engama-20 eyadlulayo, ndathenga okokugqibela i-LCD loo flue yayingena kwisitokhwe sayo!
