Monitor your energy usage with this comprehensive power meter! Key features include: - Power consumption: 0.5W - Operating voltage: 230 VAC - Display frequency: 50 Hz - Operating current: Max 16A - Wide voltage range: 230V-250V - Wattage display: 0W to 9999W (actual power display: 0~3680W) - Time display: 0 seconds to 9999 days - Voltage display: 0V~ 9,999V - Current display (Amps): 0.000A~16.000A - Frequency display: 0Hz~9999Hz - Price display: 0.00COST/KWH - 99 ,99COST/KWH - Total KWh and cost display: 0.000KWh-9999KWh, 0.00COST----9999COST - Overload alarm: Flashes when current exceeds 16A or power exceeds 3680W. Detects local power consumption below 1.0W and does not accumulate time. - Safety alarm: LCD displays overload warning. Set a power alarm value, and the OVERLOAD icon flashes when exceeding 3680W or 16A. - Multi-function socket: Monitors power (W), accumulated electricity consumption (kWh), cost, carbon dioxide emissions (KgC02), days of electricity (DAY), voltage (V), ampere (A), power factor, AC frequency (Hz), and minimum/maximum power. - Real-time monitoring: Track power consumption and flow based on daily records to ensure reasonable usage and save energy and money. - Dual Rate mode: Choose between Single Rate and Dual Rate modes (commonly used for time division). - Data Hold Function: Saves the latest data even when disconnected from the power source.
