DRK156 Surface Resistance Tester

Qhov ntsuas pocket-loj ntsuas ntsuas no tuaj yeem ntsuas ob qhov chaw impedance thiab tsis kam rau hauv av, nrog ntau yam ntawm 103 ohms / □ txog 1012 ohms / □, nrog qhov tseeb ntawm ± 1/2 ntau yam.

Daim ntawv thov
Txhawm rau ntsuas qhov impedance saum npoo, muab lub ntsuas ntsuas ntawm qhov chaw ntsuas, nias thiab tuav lub ntsuas liab (TEST) khawm, lub teeb tsis tu ncua-emitting diode (LED) qhia qhov loj ntawm qhov ntsuas qhov impedance.
103 = 1 kiloohm ntsuab LED
104 = 10k ohm ntsuab LED
105 = 100kohm ntsuab LED
106 = 1 mega ohm daj LED
107 = 10 megaohm daj LED
108 = 100 megaohm daj LED
109 = 1000 megaohm daj LED
1010 = 10000 megaohm daj LED
1011 = 100000 megaohm daj LED
1012 = 1000000 megaohm liab LED
> 1012 = insulated liab LED
Ntsuas tsis kam rau hauv av
Ntxig lub hauv av xaim rau hauv av (Ground) qhov (socket), uas insulates sab xis nrhiav kom pom electrode ntawm lub 'meter' (nyob rau tib sab ntawm lub qhov (socket). Txuas tus pas nuv ntses rau koj cov av xaim.
Muab lub ntsuas ntsuas rau saum npoo kom ntsuas, nias thiab tuav lub pob TEST, qhov tsis tu ncua luminous LED qhia qhov loj ntawm qhov tsis kam rau hauv av. Qhov ntsuas ntawm qhov ntsuas no yog ohms.
txuj
Cov cuab yeej siv ASTM tus qauv D-257 parallel electrode sensing txoj kev, uas tuaj yeem yooj yim thiab rov ntsuas ntau yam khoom siv hluav taws xob, hluav taws xob hluav taws xob, thiab qhov chaw insulating.
