INTRODUCTION
Musktool-ETCR4400 multifunctional three-phase phase voltammeter is a multifunctional instrument with touch screen, which can measure voltage amplitude, current amplitude, voltage phase, current phase, frequency, power, active power, reactive power, harmonics, and It can display the vector diagram of three-phase voltage and three-phase current in real time. In addition, it can also judge the three-phase phase sequence, inductive and capacitive circuits, test the secondary circuit, check whether the wiring of the watt-hour meter is correct or not, and repair line equipment, etc. This product is simple to operate, easy to use, fast, stable and reliable in measurement. Widely used in electric power, petrochemical, metallurgy, railway, meteorological and other units. Musktool-ETCR4400 multifunctional three-phase phase voltammeter consists of a host, current clamp and voltage test line. It adopts 5-inch touch color screen, Chinese interface, direct function, automatic measurement, simple and fast operation, accurate and reliable, and the instrument uses large-capacity rechargeable lithium battery, with data storage, data query, automatic shutdown, USB data upload and export and other functions. Since the instrument uses a dedicated metering chip, the instrument has very high-precision electrical parameter measurement, can display the changes of the parameters to be measured in real time, and has the function of saving data with one key. |
