wosume ??????? ???? ????? LED Digital Display AC 100~300V Voltmeter 0-10A Ampere Meter-Red PlusBlue-

Features: 100% brand new and high-quality.Split-type: easy to install, the transformer is separated from the instrument, and the transformer can be installed according to the actual position of the measurement. (It can lengthen the lead at the second end of the transformer to reach the ideal installation position). Specification:The range of voltage measurementAC100V-300VThe range of current measurement10A(0.00~9.99A)Display modeDouble 0.39 bright LED digital tubeDisplay color(Optional)Red + red/ red + blue/ blue + blueMeasurement accuracy1% ± 2 digitsDisplay0.39 inches LED digital tube displayMeasurement speed about 2 times per secondDimensions70 * 40 * 30 mmInstallation dimensions68 * 38 mmPower supply line, measuring line lengthabout 150mm"split" transformer lead lengthabout 100mmWorking temperature -10 ~ + 50 ?Working humidity10 ~ 80% (without condensation)Working pressure80 ~ 106 kPaSunshineNo direct exposure Package List:1 * Current voltmeter head1 * mutual inductance coil1 * Adapter Note:The wiring sequence of the instrument is: the circuit of the current loop is connected first, the 220V voltage is finally connected, after connecting the 220V power supply, it can not touch any parts and circuits behind the instrument to prevent the danger of electric shock. Split: Green terminal is connected to AC transformer CT, two yellow lines are connected to measure AC voltage, do not connect wrong, connect wrong will cause instrument damage, the responsibility is self-conceited.This meter is designed based on the principle of capacitance step-down, because the higher the frequency, the smaller the impedance of the capacitor
