Overview

The SMG2000 series digital dual clamp phase volt ampere meter features a large LCD display screen with words up to 40mm in height. It also has a white screen backlight, making the display clear at a glance and showcasing its exquisite and luxurious appearance.

Product Details

The SMG2000 series digital dual clamp phase voltmeter is another multifunctional instrument specially developed by our company for on-site testing. It has the characteristics of high precision, high stability, low power consumption, and easy use. It is possible to directly measure AC voltage and AC current without an open circuit in the tested circuit, measure the phase between two voltages, two currents, and voltage current, and indirectly measure the power factor and power of the circuit. It can also distinguish the three-phase phase sequence, transformer wiring group, inductive and capacitive circuits, test the secondary circuit and bus differential protection system, read out the phase relationship between the CT of each differential protection group, check whether the wiring of the electricity meter is correct, and repair the line equipment.
