SMG2000B digital dual clamp phase voltmeterDetailed product description：

The SMG2000B digital dual clamp phase voltmeter is a high-precision, low-cost, portable handheld, dual channel input measuring instrument designed specifically for on-site measurement of voltage, current, and phase. With this meter, it is easy to measure the phase between U-U, I-I, and U-I on site, distinguish the phase sequence of inductive and capacitive circuits and three-phase voltages, detect the wiring group of transformers, test the secondary circuit and bus differential protection system, read out the phase relationship between the CT of each differential protection group, and check the correctness of the wiring of the electricity meter.

Product Features
Reasonable limit setting and switch layout, rotating the switch can read the current, voltage (U1, I1, U2, I2) and their phase Φ. Micro power consumption setting, using only two 9V batteries, and with battery working voltage detection function, it has strong anti-interference ability and reading stability. Handheld structure, external dimensions: 85 × 167 × 35 (mm).
