Mwa zida mazana ambiri zomwe zilipo pamsika poyezera zambiri pazizindikiro zamagetsi, makina awiri ofala kwambiri ndi multimeter ndi oscilloscope. Koma adutsa pakusintha kwakukulu kwazaka zambiri kuti akhale abwinoko komanso ogwira ntchito.
Ngakhale ntchito ya zida ziwirizi ndiyofanana, sizofanana mofanana ndi momwe amagwirira ntchito komanso mawonekedwe ake. Ali ndi zina zomwe zimawapangitsa kukhala azigawo zina. Tikuuzani kusiyana konse pakati pazida ziwirizi kuti mudziwe kuti ndi iti yomwe ingakhale yothandiza kwa inu mosiyanasiyana.
Kusiyanitsa Oscilloscope ndi Graphing Multimeter
Mukafuna kupeza kusiyana pakati pazinthu ziwirizi, muyenera kungofanizira mawonekedwe awo ndikupeza kuti ndi iti yomwe imagwira ntchito yabwino pa ntchito inayake. Ndipo ndizomwe tidachita pano. Tidachita kafukufuku wambiri pazomwe zimasiyanitsa makina awiriwa, ndikukulemberani pansipa.
Mbiri Yachilengedwe
Pomwe chida choyamba chosunthira chomwe chidapangidwa chinali galvanometer mu 1820, multimeter yoyamba idapangidwa koyambirira kwa ma 1920. Katswiri waku Britain Post Office a Donald Macadie adapanga makinawo atakhumudwitsidwa ndikufunika konyamula zida zingapo zofunika kukonza matelefoni a telecom.
Oscilloscope yoyamba idapangidwa mu 1897 ndi Karl Ferdinand Braun, yemwe adagwiritsa ntchito Cathode Ray Tube (CRT) kuwonetsa kusunthika kwa osankha omwe akuyenda mosalekeza akuimira mawonekedwe amagetsi. Pambuyo pa nkhondo yachiwiri yapadziko lonse, zida za oscilloscope zidapezeka pamsika pafupifupi $ 50.
bandiwifi
Ma oscilloscopes otsika amakhala ndi bandwidth yoyambira ya 1Mhz (MegaHertz) ndikufikira MegaHertz ochepa. Kumbali ina, graphing multimeter ili ndi chiwongolero cha 1Khz (KiloHertz) chokha. Ma bandwidth ochulukirapo amafanana ndi zowunikira zambiri pamphindikati zomwe zimabweretsa mawonekedwe olondola komanso olondola.
Maonekedwe: Kukula ndi Zida Zoyambira
Oscilloscopes ndi zida zopepuka komanso zotheka zomwe zimawoneka ngati kabokosi kakang'ono. Ngakhale pali zofunikira zina zomwe ndizokwera. Kujambula ma multimeter, komano, ndi ochepa mokwanira kunyamula mthumba lanu.
Zowongolera ndi chinsalu chili kumanzere ndi kumanja kwa oscilloscope. Mu oscilloscope, kukula kwazithunzi ndizokulirapo poyerekeza ndi chophimba chaching'ono cha multimeter wa graphing. Chophimbacho chimakwirira pafupifupi 50% ya chipangizocho mu oscilloscope. Koma pa multimeter ya graphing, ili pafupi 25%. Zina zonse ndizowongolera ndi zolowetsa.
Zojambula Pazenera
Zithunzi za Oscilloscope ndizokulirapo kuposa za multimeter ya graphing. Pazenera la oscilloscope, pali gridi yokhala ndi mabwalo ang'onoang'ono otchedwa magawano. Izi zimapereka kusinthasintha komanso kusinthasintha ngati pepala la graph. Koma mulibe ma gridi kapena magawano pazenera la graph multimeter.
Madoko Olowera Jacks
Nthawi zambiri, pali njira ziwiri zolowera pa oscilloscope. Njira iliyonse yolowera imalandira chizindikiro chodziyimira payokha pogwiritsa ntchito ma probes. Mu multimeter ya graphing, pali madoko atatu olowera otchedwa COM (wamba), A (pakadali pano), ndi V (pamagetsi). Palinso doko loyambira kunja kwa oscilloscope komwe kulibe pa multimeter ya graphing.
amazilamulira
Zowongolera mu oscilloscope zidagawika magawo awiri: zowongoka komanso zopingasa. Gawo lopingalo limayang'anira malingaliro a X-axis ya graph yopangidwa pazenera. Gawo lofukula limayang'anira olamulira a Y. Komabe, palibe zowongolera zowongolera graph mu graph multimeter.
Pali kuyimba kwakukulu mu graphing multimeter yomwe muyenera kutembenuza ndikuloza chinthu chomwe mukufuna kuyeza. Mwachitsanzo, ngati mukufuna kuyeza kusiyanasiyana kwamagetsi, ndiye kuti muyenera kuyika batani kuti "V" yodziwika mozungulira kuyimba. Zowongolera izi zimayandikana ndi chinsalu cha oscilloscope, kutsogolo kwa gawo loyimirira.
Mu multimeter ya graphing, zotsatira zosasintha ndizofunika. Kuti mupeze graph, muyenera kudina batani la "Auto" pansipa pazenera. Ma Oscilloscopes amakupatsani graph posintha. Mutha kudziwa zambiri pa graph pogwiritsa ntchito ma knob owongoka komanso opingasa komanso gulu loyandikira pazenera.
Mabatani okhala ndi mtengo ndikutulutsa mtengo wamayeso atsopano amapezeka batani "Auto" likangotha. Mabatani osungira zotsatira mu oscilloscope nthawi zambiri amapezeka pamwambapa.
Mitundu Yosesa
In ndi oscilloscope, mutha kusintha kusesa kwanu kuti mupeze graph pansi pamikhalidwe yomwe mungathe kukhazikitsa. Izi zimatchedwa kuyambitsa. Ma multimeter ojambulidwa alibe njira iyi ndipo chifukwa chake, alibe mitundu yosiyanasiyana ya kusesera ngati ma oscilloscopes. Ma oscilloscope amathandizira pakufufuza chifukwa cha kuthekera koyambitsa.
zithunzi
Ma oscilloscope amakono amatha kujambula zithunzi za graph yomwe ikuwonetsedwa pazenera, ndikuyisunga kwa nthawi ina. Osati kokha kuti, fano akhoza anasamutsa kwa USB chipangizo kwambiri. Palibe mwazinthu izi kupezeka mu multimeter. Zabwino zomwe ingachite ndikusunga ukulu wa chinthu.
yosungirako
Pakati mpaka kumapeto ma oscilloscopes samangosungira zithunzi zokha, komanso amatha kusunga ma graph amoyo wamiyeso ina. Izi sizipezeka pa graphing multimeter iliyonse pamsika. Chifukwa cha izi, ma oscilloscopes akukhala otchuka kwambiri pakufufuza, popeza amatha kusunga zinsinsi zowerengera mtsogolo.
Munda Wogwiritsa Ntchito
Zithunzi ma multimeter ali ndipo atha kugwiritsidwa ntchito ngati zamagetsi. Koma ma oscilloscopes akugwiritsidwa ntchito pantchito ya sayansi yamankhwala kupatula zamagetsi. Mwachitsanzo, a oscilloscope itha kugwiritsidwa ntchito kuti muwone kugunda kwamtima kwa wodwala ndikupeza chidziwitso chofunikira chokhudzana ndi mtima.
Cost
Ma Oscilloscopes ndiotsika mtengo kwambiri kuposa graphing multimeter. Ma Oscilloscopes amayamba kuyambira $ 200 kupita mtsogolo. Kumbali inayi, ma multimeter ojambula amatha kupezeka pamtengo wotsika ngati $ 30 kapena $ 50.
Kuti Ukhale Wopambana
Ma Oscilloscopes ali ndi mawonekedwe ambiri kuposa graphing multimeter. Ndiponso, multimeter yojambula sichimayandikira pafupi ndi oscilloscope zikafika pazinthu zomwe ingachite. Izi zikunenedwa, sitinganene kuti oscilloscope imagunda ma multimeter mgulu lililonse ndipo muyenera kugula oscilloscope.
Oscilloscopes ndizofufuza. Zithandizira kupeza zolakwika mdera lomwe limafunikira mafunde olondola komanso osavuta. Koma, ngati cholinga chanu ndikungopeza zazikulu ndikungoyang'ana mawonekedwe amtunduwu, ndiye kuti mutha kugwiritsa ntchito graph multimeter mosavuta. Sichidzakulepheretsani inu pankhaniyi.
Mutha kuwerenga: Momwe Mungagwiritsire Ntchito Oscilloscope
Ndine Joost Nusselder, woyambitsa Tools Doctor, content marketer, and dad. Ndimakonda kuyesa zida zatsopano, ndipo pamodzi ndi gulu langa ndakhala ndikupanga zolemba zakuya zamabulogu kuyambira 2016 kuthandiza owerenga okhulupirika ndi zida & malangizo opangira.
