shockley AC 80-300V 100A Energy meter Voltage Current Power Factor Frequency (1 PC) Voltmeter  (Digital)

Feature:52 x 26 mm color LCD screen. display voltage, current, active power and electric quantity values simultaneously.Memory function: when the meter is in use, the cumulative value of the meter's power is stored automatically (previous power data is saved)Clear method: Hold press the button for 5 seconds, and the accumulated electric energy will be cleared.Parameters:Measuring range: 80.0-300V;Measuring accuracy: 1% ± 2digitsTest speed: 2 times per secondAlternating current: 0-99.99A, current resolution is 0.01A, when it exceeds 100A, it will display 100.0ASize: 79 x 43 x 48 mm/ 3.2 x 1.7 x 1.9 inchViewable screen size: 52 x 26 mm/ 2.1 x 1.1 inchNotes:Voltage input (yellow terminal) and current transformer secondary input (blue terminal) cannot be connected to be wrong, otherwise the instrument will be burned out.It is only suitable for pure 50Hz-electric power supply. The meter will get permanent damage if you measure the square wave, direct current-to-ac inverter output and modified sine wave.Remember not to squeeze the LCD screen of the instrument during the installation of the instrument, otherwise garbled or broken codes will occur.Please allow slight dimension error due to manual measurement.Please allow slight color difference due to different monitor.
