ES2000B large-diameter three-clamp current-voltage phase voltammeter

1. Features
B Large-diameter three-phase digital phase voltammeter, also called multi-functional three-phase digital phase voltammeter, is specially designed for on-site measurement of voltage, current, power, power factor, frequency and phase. A high-quality, multi-functional, high-precision, intelligent, portable and handheld measuring instrument. It is widely used in power inspection, power audit, meter installation and relay protection, differential detection, start-up test, industrial and mining enterprises, scientific research institutions and other departments. Instrument testing is accurate, fast, simple, stable and reliable.
B The large-diameter three-phase digital phase voltammeter can not only directly measure AC voltage values, AC current values, the phase between voltages, between currents, and between voltage and current, and power frequency, it also has other measurement capabilities. Function: Judgment of inductive current and capacitive circuit, check transformer wiring group, check whether the electric energy meter is connected correctly. It is an ideal instrument to grasp the power usage and conduct secondary circuit inspection.
B Large-diameter three-phase digital phase voltammeter consists of a host, a current clamp, and a test line. It simultaneously stores a group of data and has the function of static data storage. It has the functions of reading, checking, saving, reporting, printing and other historical data.
