Energy meter with voltage and current monitoring and a multifunction wattmeter - Clear operation indicator: when wired correctly, the meter’s status light remains on, confirming proper connection and reliable performance. - Safe installation requires a qualified electrician: read the manual before installing the energy meter to ensure correct wiring and safe operation. - Protective enclosure option: in locations where equipment damage could occur, install the wattmeter inside a protective housing to shield and protect the device. - Wiring guidance: connect according to the schematic on the energy meter’s keypad cover or the corresponding diagram in the manual. To prevent abnormal operation or meter burnout from poor contact, accommodate multiple copper conductors as required. - Practical use scenarios: - Residential main panel: monitor total household energy consumption and identify high-load appliances. - Small business or workshop: track power usage on dedicated circuits to optimize energy use and protect equipment. - Harsh or high-risk environments: install in a protective enclosure to reduce exposure risk and extend the meter’s life.
