FR2020B Large-diameter three-phase digital phase voltmeter, also known as multi-function three-phase digital phase volt-ampere meter, is a high-quality, multi-functional, high-precision, intelligent, portable handheld measuring instrument designed for on-site measurement of voltage, current, power, power factor, frequency, and phase. Widely used in electricity inspection, power inspection, power meter and relay protection, differential detection, start-up test, industrial and mining enterprises, scientific research institutions and other departments. Instrument testing is precise, fast, simple, stable and reliable.
        FR2020B Large-diameter three-phase digital phase voltmeter has the ability to directly measure the AC voltage, AC current, the phase between voltage, between currents and the phase between voltage and current, it also has other measurement judgment functions, judge the inductive current and capacitive circuit,check the transformer wiring group,check whether the power meter is wired correctly. It is the ideal instrument for checking the use of power and performing secondary circuit inspection.
        FR2020B Large-diameter three-phase digital phase voltmeter is composed of a host, current clamp, and test line, and stores 400 sets of data at the same time, and has a data static storage function. With historical data read, consult, save, report, print and other functions.

Function	Measure three-phase AC voltage, current, voltage phase, current phase, voltage and current phase, frequency, phase sequence, active power, reactive power, apparent power, power factor, current vector sum,judging the transformer wiring group, inductive, capacitive circuit, test secondary circuit and busbar protection system,read out the phase relationship between the CTs of the differential protection groups, check the correctness of the wiring of the watt-hour meter, repair the line equipment, etc.
