Product Name: Cable Semi-Conductive Shielding Layer Resistivity Tester Model NO.: BT-900A Customized: Customized Certification: CE, ISO Display Type: Digital only Accuracy: 0.5% Color: White Power: AC220V Trademark: Fangyuan Transport Package: Wooden Case Specification: 360(L)x420(W)x120(H)mm Origin: Hebei, China Product Description Cable Semi-Conductive Shielding Layer Resistivity TesterProduct DescriptionBT-900A cable semi-conductive shielding layer resistivity tester is designed according to the test methods and technical specifications specified in the national standard IEC60840. It is used to test the resistivity of high-voltage cable semi-conductive inner and outer shielding layers.Using the principle of four-terminal current-voltage step-down method, the influence of contact resistance and lead resistance generated in the test can be effectively eliminated.The resistance of the shielding layer of cables with different diameters can be measured quickly and accurately through a dedicated test stand.The electrical box has a high-precision digital voltmeter with a measurement range of 10μV - 2V.High stability DC constant current source, the output current is continuously adjustable from 0.1μA - 10mA, the measurement resistivity range is wide from 10-104Ω·m, the measurement resistance value is directly displayed digitally: the unit and decimal point are also automatically displayed, the instrument has Polarity switching and self-calibration function.Technical Parameter1.Measuring range: Resistivity 10-5~ 104Ω·m Resistance 10-3~ 107Ω2.Measurement accuracy:±(0.5% reading + 2 words) 20MΩ range ±(3% reading + 2 words) (at 0.1mA, 2V)3.Voltage range:20 mV, 200 mV, 2V4.Test current:0.1μA, 1μA, 10μA, 100μA, 1mA, 10mA5.Display: 3 1/2 digits LED digital display 0 ~1999, unit,decimal point,polarity display automatically6.The test frame: Cable conductive shield diameter: 10mm~ 35mm Cable insulation shield diameter: 50mm~ 140mm Potential electrode spacing: 50mm±0.25mm The distance between the current electrode and the potential electrode is> 25mm Equipped with 13 internal shielding potential electrode and current electrode7.
