UPM304 是一種能測(cè)量三相系統(tǒng)電氣參數(shù)的數(shù)字表。它可測(cè)量甚至被扭曲的波形。 (UPM304 is a digital meter able to measure the electrical parameters on three-phase systems. It provides accurate measurements even by distorted waveform.)

高亮度 LED 顯示屏，確保即使在艱難的環(huán)境照明條件下的關(guān)注。(The high brightness LED display ensure maximum visibility even in difficult environment lighting condition.)

用戶可方便通過(guò)儀表按鈕盤(pán)或經(jīng)由 PC 機(jī)設(shè)置工作參數(shù)?？赏ㄟ^(guò)選項(xiàng)定制基本儀表適合特定應(yīng)用。(The working parameters can be easily set up by instrument keypad or by PC. The basic instrument can be customized with some options to fit the specific application.)

UPM304 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。(UPM304 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.)

UPM304 可替代許多指針表 ( 模擬表 ) ，如電壓表，電流表，有功功率表，無(wú)功功率表，頻率表，功率因數(shù)表，電能表 ( 電度表 ) 等單一功能儀表。(UPM304 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters, varmeters, frequency-meters, powerfactor-meters, energy-meters, etc.)
