Digital Voltmeter abbreviated as DVM is an instrument used to measure the electrical potential difference between two points in a circuit . The voltage could be an alternating current (AC) or direct current (DC). Features: Wide range of applications: Can measure the power, current, voltage, temperature, etc. of connected appliances, can also set the timing and check the battery, and can clearly see the power consumption. - Full viewing angle color LCD screen. - Made of nylon material, durable, stable installation. - The split type transformer has a buckle for easy installation and assembly. - The closed type transformer needs to be threaded from the center of the transformer circle.
