The SMG2000B Digital Dual-Clamp Phase Voltmeter is a high-precision, low-cost, portable handheld, dual-channel input measuring instrument specifically designed for on-site measurement of voltage, current, and phase. With this meter, it is convenient to measure the phase between U-U, I-I, and U-I on site, identify inductive and capacitive circuits and the phase sequence of three-phase voltages, detect the connection group of transformers, test secondary circuits and bus differential protection systems, read the phase relationships between CTs in differential protection groups, and check the correctness of watt-hour meter wiring. It uses clamp-type current transformer conversion to input the measured current, so there is no need to disconnect the circuit under test during measurement. When measuring the phase between U1-U2, the two input circuits are completely isolated, thus completely avoiding possible short circuits in the tested circuit caused by incorrect wiring, which could burn out the measuring instrument.
