DRK156 Surface Resistance Tester

Miyero yoyesera ya mthumba iyi imatha kuyeza kulephera kwapadziko lonse komanso kukana pansi, kosiyanasiyana kuchokera ku 103 ohms / □ mpaka 1012 ohms / □, ndi kulondola kwa ± 1/2 osiyanasiyana.

Mapulogalamu
Kuti muyeze kutsekeka kwa pamwamba, ikani mita pamwamba kuti muyezedwe, dinani ndikugwira batani la kuyeza kofiira (TEST), diode yowunikira mosalekeza (LED) ikuwonetsa kukula kwa kuipitsidwa kwapamtunda.
103 = 1 kilooohm wobiriwira wa LED
104 = 10k ohm wobiriwira LED
105 = 100kohm wobiriwira LED
106 = 1 mega ohm chikasu cha LED
107 = 10 megaohm yellow LED
108 = 100 megaohm yellow LED
109 = 1000 megaohm yellow LED
1010 = 10000 megaohm yellow LED
1011 = 100000 megaohm yellow LED
1012 = 1000000 megaohm yofiira ya LED
> 1012 = kuwala kofiira kwa LED
Yesani kukana pansi
Ikani chingwe chapansi pansi (Ground) socket, chomwe chimateteza mbali yakumanja yozindikira electrode ya mita (mbali imodzi ndi socket). Lumikizani kopanitsa ng'ona ku waya wanu wapansi.
Ikani mita pamtunda kuti muyesedwe, dinani ndikugwira batani la TEST, LED yowunikira mosalekeza ikuwonetsa kukula kwa kukana pansi. Chigawo cha muyeso uwu ndi ma ohms.
luso muyezo
Chidacho chimagwiritsa ntchito njira ya ASTM ya D-257 yolumikizira ma elekitirodi yofananira, yomwe imatha kuyeza mobwerezabwereza ma conductive osiyanasiyana, kutulutsa kwamagetsi, komanso malo otchingira.
