K-D1410體積表面電(dian)(dian)(dian)(dian)阻(zu)率測試(shi)儀(yi)既可測量(liang)(liang)超高電(dian)(dian)(dian)(dian)阻(zu)，又(you)可測極(ji)微(wei)弱電(dian)(dian)(dian)(dian)流。采用了大規模集成(cheng)電(dian)(dian)(dian)(dian)路以及的技 術，使儀(yi)器體積小、重量(liang)(liang)輕、準確度高。以數字液晶顯示電(dian)(dian)(dian)(dian)阻(zu)并同時直接顯示流過被測電(dian)(dian)(dian)(dian)阻(zu)的電(dian)(dian)(dian)(dian)流。電(dian)(dian)(dian)(dian)阻(zu)量(liang)(liang)程從1×104Ω ～1×1018Ω， 電(dian)(dian)(dian)(dian)流測量(liang)(liang)范(fan)圍 為(wei)2 ×10-4A ～1 ×10-16A。機內測試(shi)電(dian)(dian)(dian)(dian)壓為(wei)DC10V、50V、100V、250V、500V、1000V。
