Electrical Ammeters, AC100-300V AC0-10A Digital LED Display AC 100~300V Voltmeter 0-10A Ampere Meter with Current Voltmeter Head for Measuring AC Voltage-2-

Specification: The range of voltage measurementAC100V-300V The range of current measurement10A(0.00~9.99A) Display modeDouble 0.39 bright LED digital tube Display color(Optional) #1 Red + red/ #2 red + blue Measurement accuracy1% ± 2 digits Display0.39 inches LED digital tube display Measurement rate about 2 times per second Dimensions70 * 40 * 30 mm Installation dimensions68 * 38 mm Package List: 1 * Current voltmeter head 1 * mutual inductance coil 1 * 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, so it is not suitable to be used in high-frequency electronic rate regulation, non-city electric sine waves frequency, or other occasions where there are high-frequency components, otherwise it is easy to burn down! When selecting the range, the larger the range is, the greater the range is, the greater the error is. It is suggested that 1.5 times the actual test value be.
