I-6.I-voltages ye-four output (10,50,100,500) ifumaneka kuvavanyo lokumelana neempahla ezahlukeneyo zempahla.
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.

Iiparamitha zobuGcisa

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 sinokuzinza, funda ixabiso elincinane lexabiso elihambelanayo lokumelana 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.
