Vavanya ukumelana kwelaphu ukusuka kwinqanaba ukuya kwelinye.
GB 12014-2009
1.Adopt isiboniso sedijithali esineenombolo ezi-3 1/2, isekethe yokulinganisa ibhulorho, ukuchaneka okuphezulu kokulinganisa, ukufunda okulula nokuchanekileyo.
2. Isakhiwo esiphathwayo, ubungakanani obuncinci, ubunzima obulula, kulula ukusisebenzisa
3. Ingasebenza ngebhetri, isixhobo singasebenza kwimeko yokuxhonywa komhlaba, singaphuculi kuphela amandla okulwa nokuphazamiseka kwaye sisuse ukhathalelo lwentambo yombane, singasetyenziswa nakwiimeko ezimiselweyo umbane wangaphandle olawula i-voltage.
4. Isibali-xesha esakhelwe ngaphakathi, isitshixo sokufunda esizenzekelayo, uvavanyo olulula
5. Uluhlu lokulinganisa ukumelana lufikelela kwi-0 ~ 2×1013Ω, yindlela yangoku yokulinganisa ukumelana nokuchasana kwe-point ukuya kwi-point esisixhobo sedijithali esomeleleyo. Sesona sixhobo silungileyo sokulinganisa ukumelana nomthamo kunye nokuchasana nomphezulu wezinto zokukhusela. Isisombululo esiphezulu yi-100Ω.
6. Iintlobo ezi-4 ze-(10,50,100,500) ze-voltage yokukhupha, ezifanelekileyo kuzo zonke iintlobo zovavanyo lokumelana nezixhobo zempahla.
7. Ibhetri eyakhelwe ngaphakathi esebenza ngokuphezulu ekwaziyo ukutshajwa, kuphephe ingxaki yokutshintsha ibhetri, wonge iindleko zokutshintsha ibhetri.
8. Ujongano lokusebenza olusekelwe kubuntu. Isikrini esikhulu, isikrini se-LCD esikhanyayo kakhulu, ukongeza kwisiboniso seziphumo zokulinganisa, kukho isiboniso somsebenzi wokulinganisa, isiboniso se-output voltage, isiboniso seyunithi yokulinganisa, isiboniso sesikwere esiphindaphindayo, isiboniso se-alamu ye-voltage ephantsi yebhetri, isiboniso se-alamu esingasebenzi kakuhle, lonke ulwazi ngokujonga nje.
1. Umlinganiselo wokumelana: 0 ~ 2×1013 (Ω)
2. Umboniso: Isikrini esikhulu esinobubanzi obungama-3 1/2 kunye nesibonisi sedijithali esikhanyayo yangasemva
3. Ixesha lokulinganisa: 1min ~ 7min
4. Impazamo esisiseko yokulinganisa ukumelana:
5. Isisombululo: umboniso wesixhobo kuluhlu ngalunye ungazinza, ixabiso elincinci lexabiso lokumelana elihambelanayo kufuneka libe ngaphantsi okanye lilingane noluhlu lwempazamo evumelekileyo ye-1/10.
6. Impazamo ye-voltage yeqhosha lokugqibela: impazamo ye-voltage yeqhosha lokugqibela lesixhobo ayidluli kwi-± 3% yexabiso elilinganisiweyo
7. Umxholo we-voltage yeqhosha lokugqibela: ixabiso lesikwere eliphakathi kwe-root le-voltage yeqhosha lokugqibela lesixhobo alikho ngaphezulu kwe-0.3% yecandelo le-DC.
8. Impazamo yexesha lokulinganisa: impazamo yexesha lokulinganisa yesixhobo ayidluli kwi-±5% yexabiso elibekiweyo.
9. Ukusetyenziswa kwamandla: ibhetri eyakhelwe ngaphakathi ingasebenza ngokuqhubekayo iiyure ezingama-30. Ukusetyenziswa kwamandla kombane wangaphandle kungaphantsi kwe-60mA.
10. Umbane: i-voltage elinganisiweyo (V): DC 10, 50, 100, 500
Umbane: Amandla ebhetri ye-DC 8.5 ~ 12.5V
