UPM305 是一种能测量三相系统电气参数的数字表。它甚至可以测量被扭曲的波形。(UPM305 is a digital meter able to measure the electrical parameters on three-phase systems. It provides accurate measurements even by distorted waveform.)

UPM305 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。(UPM305 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.)

三个高亮度 LED 显示屏，确保照明条件不好时获得可视性。 用户可方便通过仪表按钮盘设置工作参数。(Three high brightness LED displays ensure maximum visibility even in difficult environment lighting condition. The working parameters can be easily set by the instrument keypad.)

UPM305 可替代多种指针表( 模拟表)，如电压表，电流表，有功表，无功表，频率表，功率因数表，电能表(电度表)等单一功能仪表。(UPM305 replaces multiple analog meters as well as single function meters such as voltmeters, ammeters, wattmeters,
varmeters, frequency-meters, powerfactor meters,
energy-meters, etc.)

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.)
