本系列數(shù)字位瓦特表具有3個(gè)電壓檔位，3個(gè)電流檔位，及9個(gè)瓦特檔位，適當(dāng)?shù)慕馕龆扰czui合理的價(jià)位是你*的選擇。

產(chǎn)品特點(diǎn)

．基本+/- 0.1%的準(zhǔn)確度
．電壓、電流與瓦特皆為true rms 量測
．電壓及電流具有手動(dòng)或自動(dòng)的換檔功能，及自動(dòng)換檔之頻率量測
．使用4 1/2位類比數(shù)位轉(zhuǎn)換器為基準(zhǔn)，提供高準(zhǔn)確度、高解析度及高穩(wěn)定度的量測
．使用3個(gè)多工的顯示器，可依所需來選擇，且均可選擇所有的量測功能(vrms, arms, vrms, pf, va, var, hz)
．具有電壓三段、電流三段及瓦特九段的輸入檔位選擇
．自動(dòng)保存關(guān)機(jī)前之設(shè)定狀態(tài)，關(guān)機(jī)后自動(dòng)回復(fù)原先設(shè)定
．輸入電流峰值超過檔位警告
