Description This AC meter offers a 360-degree viewing angle with no blind spots, and with its backlight, it's clearly visible day and night. This meter can measure AC voltage 50.0-300.0V, AC current 0.0-99.99A, power factor 0.00-1.00PF, active power 0-30000W, electrical energy 0-99999kWh, and frequency 45.0-65.0Hz. All 6 data points are displayed simultaneously on one screen. When the device is turned off, the electrical energy value is automatically saved. This wattmeter reads the value after power-on and continues to increment the stored value. The power reset button is located at the bottom right of the meter. You can press and hold the button with a needle for 4 seconds to reset the electrical energy. This multifunctional volt amp wattmeter is easy to install in a panel. Widely used in power measurement systems, schools, markets, industry, laboratories, etc. This 1-phase meter is made of high-quality flame-retardant ABS material and a high-precision chip, ensuring safe use with high accuracy. Please note: This meter can only measure 50/60 Hz AC current. It will be destroyed if used to measure square waves, inverter output, or non-standard sine waves.
