CH400變壓器電量測量儀系列可廣泛用于各種小型變壓器或整流器電源等廠家的生產(chǎn)流水線測試，實驗室試品試驗等場合。該系列儀器采用數(shù)字同步采樣及微機(jī)技術(shù)，能準(zhǔn)確測量變壓器的初級電壓、電流、功率、功率因數(shù)的真有效值，次級電壓、電流的真有效值（交流）或平均值（直流），次級電壓紋波的真有效值。內(nèi)置電子負(fù)載能方便的進(jìn)行空、負(fù)載轉(zhuǎn)換測試。具有測試速度快、精度高、使用方便、顯示直觀等優(yōu)點。

CH400 transformer coulometer can be widely applied in test on production line of small manufacturer of transformer or rectifier power or in labs. The meter adopts digital synchronous sampling and micro technology to accurately measure true RMS of transformer’s primary voltage, current, power, power factor, true RMS (AC) or average (DC) of secondary voltage and current, true RMS of secondary voltage ripple. Built-in electric load can make the instrument conveniently perform idling/load conversion. The meter has the characteristics of having high speed, high accuracy, easy operation and direct display.
