DRK156 Surface Resistance Tester

Le mitha yokuvavanya ubungakanani bepokotho inokulinganisa zombini i-impedance yomhlaba kunye nokuchasana nomhlaba, kunye noluhlu olubanzi ukusuka kwi-103 ohms / □ ukuya kwi-1012 ohms / □, ngokuchaneka kwe-± 1/2 uluhlu.

Usetyenziso
Ukulinganisa i-impedance surface, beka imitha phezu komhlaba ukuze ulinganiswe, cinezela kwaye ubambe iqhosha elibomvu lokulinganisa (TEST), i-diode eqhubekayo yokukhanya ekhanyayo (i-LED) ibonisa ubukhulu be-impedance surface elinganisiweyo.
103=1 kilooohm i-LED eluhlaza
104=10k ohm i-LED eluhlaza
105=100kohm i-LED eluhlaza
106=1 mega ohm iLED etyheli
107=10 megaohm yellow LED
108=100 megaohm yellow LED
109=1000 megaohm iLED etyheli
1010=10000 megaohm yellow LED
1011=100000 megaohm yellow LED
1012=1000000 megaohm i-LED ebomvu
>1012=i-LED ebomvu egqunyiweyo
Ukulinganisa ukumelana nomhlaba
Faka ucingo oluphantsi emhlabeni (Ground) socket, ekhusela i-electrode yokufumanisa kwicala lasekunene lemitha (kwelinye icala njengesokethi). Qhagamshela ikliphu yengwenya kucingo lwakho lwasemhlabeni.
Beka imitha phezu komhlaba ukuze ulinganiswe, cinezela kwaye ubambe iqhosha le-TEST, i-LED eqhubekayo ekhanyayo ibonisa ubukhulu bokumelana nomhlaba. Iyunithi yalomlinganiselo zii-ohms.
umgangatho wobugcisa
Isixhobo sisebenzisa umgangatho we-ASTM we-D-257 we-parallel electrode sensing method, enokulinganisa ngokulula nangokuphindaphindiweyo ukukhutshwa kwe-electrostatic, kunye ne-insulating surfaces.
