6. Installation and Maintenance Recommendations

• Pre-Installation Inspection: Confirm that the rated voltage of the meter matches the on-site power grid voltage, and check the wiring terminals for looseness or poor contact to avoid potential faults caused by improper connection.
• Power Supply Requirements: Ensure a stable external power supply for the meter itself; stable power input is a prerequisite for the meter’s accurate measurement and long-term stable operation.
• Communication Debugging: After connecting the Modbus cable, set the communication address and match the baud rate on the host computer or SCADA system to ensure smooth data transmission and normal system docking.
• Regular Calibration: Despite the meter’s high-precision performance, on-site calibration is recommended every 2 years in accordance with industry standards to maintain long-term metering accuracy and compliance.
• Protection Measures: When installing the meter in a panel cabinet, reserve sufficient ventilation space to prevent overheating caused by high temperature, which may affect the meter’s performance and service life.
