Product Description

Chapter 1. General introduction

The 3U(3I) combined meter is used to measure and display the direct digital reading of voltage/current value in the three-phase electrical line. The UIF combined meter is used to measure and display the direct digital reading of voltage, current, and frequency values in the single-phase electrical line. One meter can finish the measuring tasks of three common meters.
