· 小而強(qiáng)大 (Small and powerful)
· 用戶友好 (User friendly)
· 高反差高亮度 LED 顯示屏 (High contrast bright LED display)
· True RMS測(cè)量 (True RMS measurements)
· 可顯示多達(dá) 30 電氣參數(shù) (More than 30 electrical parameters displayed)

UPM304是一種能測(cè)量三相系統(tǒng)主要電氣參數(shù)的數(shù)字表。它可測(cè)量甚至被扭曲的波形。(UPM303 is a digital meter able to measure the main electrical parameters on three-phase systems. It provides accurate measurements even by distorted waveform.)

高亮度LED顯示屏，確保光照條件不好時(shí)獲得可視性。(The high brightness LED display ensures maximum visibility even in difficult environment lighting condition.)

用戶可方便通過(guò)儀表按鈕盤或經(jīng)由PC機(jī)設(shè)置工作參數(shù) (The working parameters can be easily set up by instrument keypad or PC.)

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.)

UPM304是一緊湊型，費(fèi)效比高的儀表。 即可作獨(dú)立儀器，也可作廣域能源監(jiān)測(cè)和管理網(wǎng)絡(luò)的組成部分運(yùn)行。 (UPM303 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，有功功率表等單一功能儀表。 (UPM303 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters, etc.)
