SMG2000B digital double clamp phase voltammeter is a high-precision, low-cost, handheld, dual-channel input measuring instrument designed for field measurement of voltage, current and phase. With this meter, you can easily measure the phase between UU, II and UI on site, distinguish the phase sequence of inductive, capacitive circuits and three-phase voltage, detect the wiring group of the transformer, and test the secondary circuit and bus differential protection system. , Read the phase relationship between the CTs of each group of differential protection, check whether the wiring of the watt-hour meter is correct or not, etc.

Clamp-on current transformer is used to input the current under test, so there is no need to disconnect the line under test during measurement. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, so it completely avoids the possible short circuit of the line under test caused by miswiring, which may burn the measuring instrument. The display adopts a high-contrast LCD screen with characters up to 25mm, and the screen angle can be freely switched about 70° to obtain visual effects.

The outer casing of the instrument is made of engineering insulating materials, and a rubber anti-vibration protective cover is also provided.
