BT-900A chingwe cha semi-conductive shielding layer resistivity tester idapangidwa molingana ndi njira zoyesera komanso ukadaulo wofotokozedwa mu muyezo wadziko lonse IEC60840. Amagwiritsidwa ntchito poyesa resistivity ya high-voltage chingwe semi-conductive mkati ndi kunja shielding layers. Pogwiritsa ntchito mfundo ya four-terminal current-voltage step-down njira, chikoka cha kukana kukhudzana ndi kutsogolera kukana kopangidwa mu mayeso kungakhale kuchotsedwa bwino.Kukaniza kwa chingwe chotchinga cha zingwe zokhala ndi ma diameter osiyanasiyana kungayesedwe mwachangu komanso molondola kudzera mumayendedwe oyesera odzipereka.

Bokosi lamagetsi lili ndi voltmeter yolondola kwambiri ya digito yokhala ndi miyeso yosiyanasiyana ya 10μV - 2V. Kukhazikika kwapamwamba kwa DC nthawi zonse gwero lapano, zotulutsa zomwe zimatuluka zimasinthidwa mosalekeza kuchokera ku 0.1μA - 10mA, miyeso yoyezera resistivity ndi yotakata kuchokera ku 10-10⁴Ω·m, kukana kwa miyeso kumawonetsedwa mwachindunji pa digito: gawo ndi decimal point zimawonetsedwanso zokha, chidacho chimakhala ndi kusintha kwa Polarity ndikudziyesa nokha.
