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.

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.
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.
7. Umxholo wombane weqhosha lesiphelo: ingcambu ithetha ixabiso elisisikweri sesixhobo sokuphela kweqhosha umthamo wombane awukho mkhulu kune-0.3% yecandelo le-DC.
8. Impazamo yokulinganisa ixesha: impazamo yokulinganisa ixesha lesixhobo ayikho nkulu kune ± 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

11. Ngokutsho kwe-GB 12014-2009 --anti-static impahla isihlomelo A point-to-point resistant method method needs of A iseti electrode: uvavanyo electrode ezimbini 65mm ububanzi metal cylinder; Izinto ze-electrode ziyinsimbi engenasici. Izinto ze-electrode contact end is conductive rubber, kunye nokuqina kwe-60 Shore A, Ubukhulu be-6mm, kunye nokumelana nomthamo ongaphantsi kwe-500Ω. Electrode ubunzima omnye 2.5kg.
12. Ngokuhambelana ne-FZ / T80012-2012 ---impahla ecocekileyo yegumbi iphuzu-to-point yokumelana neemfuno zendlela yokukhangela isethi ye-electrodes: i-electrode yokufumanisa ezimbini. I-electrode nganye yokufumanisa iqulunqwe yi-clamp conductive kunye neepleyiti ezimbini zensimbi ezingenasici. I-clamp kufuneka ikwazi ukufaka uxinzelelo olwaneleyo ukuze ibambe isampuli kwaye iyenze inqunyanyiswe. Ummandla weplate yensimbi engenasici ngu-51 × 25.5mm.
