Product details
FR2020 three-phase digital phase voltmeter, also known as multifunctional three-phase digital phase voltmeter, is a high-quality, multifunctional, high-precision, intelligent, portable handheld measuring instrument designed for on-site measurement of voltage, current, power, power factor, frequency, and phase. Widely used in energy metering, electricity inspection, power inspection, meter installation and relay protection, differential detection, start-up testing, industrial and mining enterprises, scientific research institutions and other departments. The instrument testing is characterized by precision, speed, simplicity, stability, and reliability.
The FR2020 three-phase digital phase volt ampere meter not only directly measures AC voltage and AC current values, phase and frequency between voltages, currents, and voltage and current, but also has other measurement and judgment functions. It can judge inductive current and capacitive circuits, check transformer wiring groups, and check whether the energy meter is wired correctly. It is an ideal instrument for grasping power usage and conducting secondary circuit inspections.
The FR2020 three-phase digital phase volt ampere meter consists of a main unit, current clamp, test line, and protective cover. It can store 500 sets of data and has a static data storage function. It has functions such as historical data reading, viewing, saving, reporting, and printing.
