Discover our 5-in-1 Multifunction Energy Meter, designed for comprehensive power monitoring. **Key Features:** * **Versatile Measurement:** Accurately measures voltage, current, power factor, active power, and electrical energy. * **Automatic Resolution:** Measurement resolution adjusts automatically for optimal precision. * **Clear Digital Display:** Voltage and current are displayed on a 4-digit red 0.32-inch LED tube, while active power, electrical energy, and power factor use a 5-digit green 0.32-inch LED tube. * **High Accuracy:** Boasts a measurement accuracy of 1% ± 2 digits. * **Wide Measurement Range:** AC voltage options include AC80.0-300.0V (ideal for 220V systems) or AC200.0-450.0V (for 380V systems). AC current measures from AC0.00-100.0A with automatic resolution switching. * **Power & Energy Tracking:** Active power up to 30000W (or 45000W for 200.0-450.0V systems) and electrical energy from 0.000-99999Kwh with automatic decimal point conversion. * **Fast Refresh Rate:** Measures approximately 2 times per second. **Easy Installation & Operation:** 1. Connect the current transformer's secondary end (green wire) to the meter's blue terminal. Pass the measurement circuit wire through the current transformer's center hole. 2. Connect the voltage measurement wire to the meter's green terminal. Power on to begin measuring. 3. Cycle through display functions (Voltage, Current, Active Power, Electrical Energy, Power Factor) by pressing the 'SAM CK' button. 4. To reset electrical energy (Kwh) to zero, press and hold the 'SAM CK' button for 5 seconds while the Kwh function is displayed. 5. **Data Retention:** The meter automatically saves electrical energy data during power outages, resuming accumulation from the last saved point upon power restoration. **Package Includes:** * 1 x 5-in-1 Meter with Current Transformer * 1 x User Manual
