I-1.Adopt i-3 1/2 idijithi yesiboniso sedijithali, isiphaluka sokulinganisa ibhulorho, ukuchaneka kokulinganisa okuphezulu, ukufunda okulula kunye nokuchanekileyo.
2. Isakhiwo esiphathekayo, ubungakanani obuncinci, ubunzima obulula, kulula ukuyisebenzisa
3. Inokuthi inikwe amandla ngebhetri, isixhobo sinokusebenza kwimeko yokumiswa komhlaba, kungekhona nje ukuphucula ikhono lokuchasana nokuphazamiseka kunye nokususa ukhathalelo lwentambo yamandla, ingasetyenziselwa kwiimeko eziqingqiweyo unikezelo lwamandla ombane wolawulo lwangaphandle.
4. Isibali-xesha esakhelwe ngaphakathi, isitshixo sokufunda ngokuzenzekelayo, uvavanyo olufanelekileyo
I-5.Uluhlu lokulinganisa ukuchasana ukuya kwi-0 ~ 2 × 1013Ω, inqaku langoku ukuya kwinqanaba lokumelana nomlinganiselo sisixhobo esinamandla sedijithali.Sesona sixhobo silungileyo sokulinganisa umthamo wokuxhathisa kunye nokumelana nomphezulu wezinto ezigqumayo.Esona sisombululo siphezulu yi-100Ω.
6. Iindidi ezi-4 ze-(10,50,100,500) i-voltage yemveliso, ilungele zonke iintlobo zovavanyo lokumelana nempahla.
7. Ibhetri eyakhelwe-ngaphakathi yokusebenza okuphezulu, thintela ingxaki yokutshintsha ibhetri, gcina iindleko zokutshintsha ibhetri.
8. Ujongano lomsebenzi owenziwe ngabantu.Isikrini esikhulu, ukukhanya okuphezulu kwesikrini se-LCD, ngaphezu komboniso weziphumo zokulinganisa, kukho umboniso womsebenzi wokulinganisa, umboniso wombane ophumayo, umboniso weyunithi yokulinganisa, umboniso wesikwere esiphindaphindayo, umboniso we-alamu ophantsi kwebhetri, umboniso we-alamu ye-misoperation, yonke ingcaciso ngokujonga nje.
1. Umlinganiselo wokuchasa: 0 ~ 2×1013 (Ω)
2. Bonisa: 31/2-digit screen enkulu kunye backlight digital display
3. Ixesha lokulinganisa: 1min ~ 7min
4. Impazamo esisiseko yomlinganiselo wokuchasa:
5. Isisombululo: isixhobo sokubonisa kuluhlu ngalunye lunokuzinza lufundeke ixabiso elincinane lexabiso elichasayo elihambelanayo kufuneka libe ngaphantsi okanye lilingane noluhlu lwempazamo evumelekileyo ye-1/10.
6. Impazamo yombane weqhosha lesiphelo: impazamo yombane weqhosha lesixhobo ayikho ngaphezulu kwe ± 3% yexabiso elilinganisiweyo.
7. Umxholo wombane weqhosha lesiphelo: ingcambu intsingiselo yexabiso lesikwere sesixhobo sokuphela kweqhosha lomthamo we-voltage ripple umxholo awukho mkhulu kune-0.3% yecandelo le-DC.
8. Iphutha lexesha lokulinganisa: impazamo yokulinganisa ixesha lesixhobo ayikho ngaphezu kwe-± 5% yexabiso elimiselweyo.
9. Ukusetyenziswa kwamandla: ibhetri eyakhelwe-ngaphakathi ingasebenza ngokuqhubekayo kwiiyure ze-30.Ukusetyenziswa kwamandla ombane wangaphandle kungaphantsi kwe-60mA.
10. Ubonelelo lwamandla: umbane olinganisiweyo (V) : DC 10, 50, 100, 500
Ubonelelo lwamandla: amandla ebhetri yeDC 8.5 ~ 12.5V
