I-DRK156 Surface Resistance Tester

Le mitha yokuhlola engusayizi wephakethe ingakala kokubili ukuthintana kwendawo kanye nokumelana nomhlaba, ngebanga elibanzi ukusuka ku-103 ohms/ □ kuya ku-1012 ohms/ □, ngokunemba kwebanga elingu-±1/2.

Izinhlelo zokusebenza
Ukuze ulinganise i-impedance yangaphezulu, beka imitha endaweni ezolinganiswa, cindezela futhi ubambe inkinobho yesilinganiso esibomvu (TEST), i-diode ekhipha ukukhanya eqhubekayo (LED) ibonisa ubukhulu be-impedance yendawo elinganiselwe.
103=1 kilooohm i-LED eluhlaza
104=10k ohm i-LED eluhlaza
105=100kohm i-LED eluhlaza
106=1 megaohm i-LED ephuzi
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 i-LED ebomvu
>1012=i-LED ebomvu evaliwe
Linganisa ukumelana nomhlabathi
Faka intambo yaphansi esokhethini (Ephansi), evikela i-electrode etholakala ohlangothini lwesokudla lwemitha (ngasohlangothini olufanayo nesokhethi). Xhuma isiqeshana sengwenya entanjeni yakho yaphansi.
Beka imitha endaweni ukuze ikalwe, cindezela bese ubamba inkinobho ethi TEST, i-LED eqhubekayo ekhanyayo ikhombisa ubukhulu bokumelana nomhlaba. Iyunithi yalesi silinganiso i-ohms.

Izinga Lobuchwepheshe
I-ACL385 isebenzisa indlela ye-ASTM ejwayelekile ye-D-257 yokuzwa i-electrode parallel, engakala kalula futhi ngokuphindaphindiwe ukukala okuhlukahlukene kokukhishwa kwe-electrostatic, kanye ne-insulating.
