Feature 1ROW PIN PULSE: The newly upgraded row pin pulse version is more suitable for integrated use of PCBs, making it easier to measure power and calibrate errors. 2COMM INTERFACE: The physical layer uses a comm interface from UART to TTL, with a baud rate of 9600, 8 data bits, 1 stop bit, and no verification. 3FUNCTION CODES: Supports 0x03 (read hold register), 0x04 (read input register), 0x006 (write single register), 0x41 (calibration), 0x42 (power reset), etc. The 0x41 function code is only for internal use (address can only be 0xF8). 4HOST SLAVE MACHINE: The slave does not need to reply to the host and uses the address OxF8 as the universal address, which can only be used in a single slave device and can be used as a calibration address. 5CRC VERIFICATION: Adopts a 16 bit format, occupying two bytes, and generates a polynomial of X16+X15+X2+1, the polynomial value used for calculation is 0xA001.Item Type: Multifunction Meter ModuleMaterial: PCBVoltage Measurement Range: 80-260VResolution: 0.1VMeasurement Accuracy: 0.5%Current Measurement Range: 0-100AStarting Current: 0.02AResolution: 0.001AMeasurement Accuracy: 0.5%Active Power Measurement Range: 0-23kWStarting Power: 0.4WResolution: 0.1WDisplay Format: <1000W Display 1 decimal place, such as 999.9W; 1000W, display only integers, such as 1000WPower Measurement Range: 0.00-1.00Resolution: 0.01Measurement Accuracy: 1%Frequency Measurement Range: 45Hz-65HzResolution: 0.1HzMeasurement Accuracy: 0.5%Active Energy Metering Range: 0-9999.99kWhResolution: 1WhMeasurement Accuracy: 0.5%Display Format: <10kWh, display unit is Wh (lkWh=1000Wh), such as 9999Wh; 10kWh, displayed in kWh, such as 9999.99kWhElectric Energy Reset: Software ResetPower Over Limit Alarm: The active power threshold can be set, and when the measured active power exceeds the set threshold, the alarm status will be set. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Test Module1 x User Manual1 x Closed CT
