產(chǎn)品別稱
智能回路電阻測試儀、智能接觸電阻測試儀、接觸電阻測試儀、開關(guān)回路電阻測
試儀、接觸回路電阻測試儀
產(chǎn)品簡介
智能回路接觸電阻測試儀是用于測量開關(guān)、斷路器、變壓器等設(shè)備的接觸電阻、
回路電阻的專用測試設(shè)備。其采用典型的四線制測量法，通過輸出一個直流電流
，施加于被測體的兩個端鈕之間，并測量電流流過被測體所產(chǎn)生的壓降，然后通
過電壓和電流之比得出被測體的直流電阻。主要由恒流源、前置放大器、A/D轉(zhuǎn)換
器、指示裝置等部分組成。
Loop resistance tester is the special test equipment for measuring the
contact resistance and loop resistance of some devices such as switch,
circuit interrupter, and transformer and so on. It adopts the typical
four-wire method of measurement which helps get the DC resistance
through the following steps: outputting a DC current, applying the
current to the tested body by linking its two terminals, and measuring
the voltage drop when the current goes through the tested body, then
dividing the current by the voltage. In addition, it mainly consists of
constant current source, preamplifier, A/D converter, indicating device
and so on.
