UPM305 是一種能測(cè)量三相系統(tǒng)電氣參數(shù)的數(shù)字表。它甚至可以測(cè)量被扭曲的波形。(UPM305 is a digital meter able to measure the electrical parameters on three-phase systems. It provides accurate measurements even by distorted waveform.)

UPM305 是一緊湊型，費(fèi)效比高的儀表 即可作為獨(dú)立儀器，也可作為廣域能源監(jiān)測(cè)和管理網(wǎng)絡(luò)的組成部分運(yùn)行。(UPM305 is a compact, cost effective meter operating both as a stand-alone device or as an integral part of a more extensive energy monitoring and management network.)

三個(gè)高亮度 LED 顯示屏，確保照明條件不好時(shí)獲得可視性。 用戶可方便通過(guò)儀表按鈕盤(pán)設(shè)置工作參數(shù)。(Three high brightness LED displays ensure maximum visibility even in difficult environment lighting condition. The working parameters can be easily set by the instrument keypad.)

UPM305 可替代多種指針表( 模擬表)，如電壓表，電流表，有功表，無(wú)功表，頻率表，功率因數(shù)表，電能表(電度表)等單一功能儀表。(UPM305 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters,
varmeters, frequency-meters, powerfactor meters,
energy-meters, etc.)

可通過(guò)選項(xiàng)定制基本儀表適合特定應(yīng)用 (The basic instrument can be customized with some options to fit the specific application.)
