1. Characteristics
Double-clamp digital phase voltammeter is a high-quality, multi-functional, high-precision, intelligent, portable and hand-held type specially designed for on-site measurement of voltage, current, power, power factor, frequency and phase. measuring instrument. <>Widely used in departments such as electric energy measurement, power inspection, power inspection, meter installation and connection and relay protection, differential detection, start-up test, industrial and mining enterprises, scientific research institutions, etc.
Instrument testing is accurate, fast, simple, stable and reliable.
In addition to directly measuring AC voltage values, AC current values, the phase between voltages, between currents, and between voltage and current, and power frequency, the double-clamp digital phase voltammeter also has other measurement and judgment functions for inductance. Determine the current and capacitive circuits, check the transformer wiring group, and check whether the electric energy meter is connected correctly. It is an ideal instrument to grasp the power usage and conduct secondary circuit inspection.
The double-clamp digital phase voltammeter is composed of a host, a current clamp, and a test line. It simultaneously stores <> sets of data and has the function of static data storage. It has the functions of reading, checking, saving, reporting, printing and other historical data.
