UPM304是一种能测量三相系统主要电气参数的数字表。它可测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显示屏，确保光照条件不好时获得可视性。(The high brightness LED display ensures maximum visibility even in difficult environment lighting condition.)

用户可方便通过仪表按钮盘或经由PC机设置工作参数 (The working parameters can be easily set up by instrument keypad or PC.)

可通过选项定制基本仪表适合特定应用 (The basic instrument can be customized with some options to fit the specific application.)

UPM304是一紧凑型，费效比高的仪表。 即可作独立仪器，也可作广域能源监测和管理网络的组成部分运行。 (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可替代许多指针表(模拟表)，如电压表，电流表，有功功率表等单一功能仪表。 (UPM303 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters, etc.)
