UT268B Wireless Large Current Fork Meter

The Digital 3-Phase Voltammeter, part of the clamp meter series, is a high-precision, intelligent, and multifunctional industrial-frequency measurement instrument.


It uses the latest microprocessor and digital signal processing technology to measure various parameters including voltage, current, power, frequency, power factor, and phase relation. It can identify transformer connections, test inductive and capacitive circuits, and check electric energy meter wiring. With a clamp current transformer, it can safely and accurately measure power without disconnecting from the conductor, making it portable.
