The dual-clamp phase voltmeter is a high-precision, low-cost, portable, handheld, dual-channel input measuring instrument specially designed for on-site measurement of voltage, current, and phase. With this meter, it is convenient to measure the phase between circuits on site, distinguish inductive and capacitive circuits and the phase sequence of three-phase voltage, detect the connection group of transformers, test secondary circuits and bus differential protection systems, read out the phase relationship between groups of differential protection, and check whether the wiring of the watt-hour meter is correct. Therefore, when measuring, there is no need to disconnect the measured lines. The two input circuits are completely insulated and isolated, thus completely avoiding possible short circuits of the measured lines caused by incorrect wiring, which could burn out the measuring instrument. The display uses a high-contrast liquid crystal display with oversized characters for the best visual effect.
