["Description:\r\nGV13T is one light and low price-orientated module used for checking and demonstrating Voltage, Frequency and accumulating for time of generator. This module can replace old meters, for it can be one with multi-functions. It uses normal screw for connection which is more convenient for installation.\r\n\r\nFeatures:\r\nVoltage, frequency and accumulating for time can be checked and demonstrated in the mean for time;\r\nResults shown by 4-position digital LED tube\r\nSelf-recycling of parameters \r\nwith Page Turning Buttons\r\nfor Extra working power is not needed\r\n\r\nParameter demonstration\r\nPhase voltage (V)\r\nFrequency (Hz)\r\nAccumulating for time(H)\r\nCurrent for Time(for T)\r\n\r\nSpecification:\r\nWorking Power:AC 185~265V\r\nCumulative running time: 0-9999H\r\nConsuming Power:MAX 1W\r\nRecycling Time:Voltage:5s,Frequency:5s\r\nAccumulating time:2s\r\nTemperature:-20~~75\r\nVolume size (for W * H * D): 58mm * 54mm * 41mm\r\nMounting hole (for W * H): 47mm * 37mm\r\nWeight:45g\r\n\r\nPackage include:\r\n1 * GV13T Digital Voltmeter Frequency Hour Meter"]
