DRK156 Surface Resistance Tester

Iyi homwe-saizi yebvunzo mita inogona kuyera ese ari maviri epamusoro impedance uye kuramba pasi, nehupamhi hwakasiyana kubva ku103 ohms / □ kusvika 1012 ohms/ □, nekururama kwe ± 1/2 renji.

Applications
Kuyera iyo impedance yepasi, isa mita pamusoro pekuyerwa, dzvanya uye ubate iyo dzvuku kuyerwa (TEST) bhatani, iro rinoramba rakabatidzwa light-emitting diode (LED) rinoratidza ukuru hwekuyerwa kwepasi kwakayerwa.
103 = 1 kiloohm yegirini LED
104 = 10k ohm yegirini LED
105 = 100kohm yegirini LED
106=1 mega ohm yero LED
107 = 10 megaohm yero LED
108 = 100 megaohm yero LED
109 = 1000 megaohm yero LED
1010 = 10000 megaohm yero LED
1011 = 100000 megaohm yero LED
1012 = 1000000 megaohm tsvuku LED
> 1012 = insulated red LED
Kuyera kuramba pasi
Isa wire yepasi muvhu (Ground) socket, iyo inodzivirira yekurudyi yekuona electrode yemamita (kudivi rimwechete nesoketi). Batanidza clip ye alligator kune yako pasi waya.
Isa mita pamusoro pekuyerwa, dzvanya uye ubate bhatani reTEST, iyo inoramba ichipenya LED inoratidza hukuru hwekupokana pasi. Chiyero chechiyero ichi chinonzi ohms.
technical standard
Chiridzwa chinoshandisa ASTM yakajairwa D-257 parallel electrode sensing nzira, iyo inogona nyore uye kudzokorodza kuyera akasiyana conductive, electrostatic discharge, uye insulating nzvimbo.
