UPM307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。大尺寸帶背光LCD顯示屏十分高效，可確保在各種光照下有完美可視性。(UPM307 is a digital meter able to measure the electrical parameters on three-phase systems. It provides accurate measurements even by distorted waveform. The backlighted LCD display is very large and highly efficient, therefore it guarantees perfect visibility in all light conditions.)

簡(jiǎn)單的操作菜單使儀器易于使用，可快速檢驗(yàn)儀器設(shè)置和內(nèi)存狀態(tài)。(A simple menu structure makes the instrument easy to use and allows a quick check of the measured parameters.)

用戶可方便通過(guò)儀表按鈕盤設(shè)置工作參數(shù) (The working parameters can be easily set up by the instrument keypad.)

RS232或RS485串行通信端口可從儀表傳輸三相系統(tǒng)的電氣參數(shù)。(The RS232 or RS485 serial communication port allows to transfer the three-phase electrical parameters from the instrument.)

UPM307可替代多種指針表(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。(UPM307 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters,
varmeters, frequency-meters, powerfactormeters,
energy-meters, etc.）

可通過(guò)選項(xiàng)定制基本儀表以適合特定應(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。(UPM307 is a compact, costeffective meter operating both as a stand-alone device or as anintegral part of a more extensive energy monitoring and managementnetwork.)
