    Q1: What is a volt amp meter?
    A1: A digital volt amp meter is a high-precision, low-consumption, low-cost, portable, handheld, dual-channel input measuring instrument, specially designed for measuring voltage, current and phases on-site.

    Q2: How a volt amp meter works?
    A2: The volt-ampere meter adopts the clamp conversion method to input the measured current, so there is no need to disconnect the measured line during measurement. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, thus completely avoiding the short circuit of the measured line caused by miswiring and burning the measuring instrument. This is the working principle of volt ammeters.

    Q3: What can a volt amp meter do?
    A3: When the circuit under test is not open, the volt ammeter can simultaneously measure two AC voltages, currents, phases between voltages, phases between currents, phases between voltages and currents, frequency, phase sequence, active power, reactive power, apparent power, power factor, etc., the volt amp meter can also identify the transformer wiring group, inductive and capacitive circuits, test the secondary circuit and bus differential protection system, read the phase relationship between the CTs of the differential protection groups, and check the watt-hour meter wiring and line equipment.

    differential protection groups, and check the watt-hour meter wiring and line equipment.

    Tips: Volt amp meter application in a test socket

    When a device doesn't seem to be working properly, you can set the double clamp volt ampere meter to a test voltage and plug the leads into the outlet slots. If the digital voltammeter shows no voltage, you have a circuit problem that is preventing the flow of current. Or, you may find that moving the probe causes the meter to jump, which means the socket needs to be replaced. Through a volt ammeter, you may get a voltage reading that is much smaller than it actually is, indicating a circuit defect that needs attention.
