UPM304 是一种能测量三相系统电气参数的数字表。它可测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 显示屏，确保即使在艰难的环境照明条件下的关注。(The high brightness LED display ensure 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。可通过选项定制基本仪表适合特定应用。(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 是一紧凑型，费效比高的仪表 即可作为独立仪器，也可作为广域能源监测和管理网络的组成部分运行。(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 可替代许多指针表 ( 模拟表 ) ，如电压表，电流表，有功功率表，无功功率表，频率表，功率因数表，电能表 ( 电度表 ) 等单一功能仪表。(UPM304 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters, varmeters, frequency-meters, powerfactor-meters, energy-meters, etc.)
