Feature:1. Data Display: This electricity meter can display the measured AC voltage, current, frequency, power, energy and kWh, meanwhile the red and green LEDs are very clear to see.2. High Measurement Accuracy: This single phase electric energy meter uses PC flame retardant materials and accurate chips, which are safe to use. The accuracy is 1% 2 bits, and the measurement speed is 2 times per second.3. Reliable Testing: DIN rail power meter can display AC voltage and current at the same time. If the current is below 100A, simply pass the wire through the hole on the right side of the instrument to obtain AC current.4. Data Storage and Resetting: When the meter displays energy, press and hold the SAM CK key for five seconds, and the meter will reset. Automatically save the electrical energy value and cumulative time electrical energy value when the power is cut off. After reconnecting the measurement power supply, the instrument continues to accumulate data.5. Wide in Utility: This AC power meter has a built in transformer in its guide rail, which can meet the maximum load current of 100A. It can be used in fields such as schools, shopping malls, homes, industry, laboratories, etc.Specification:Item Type: Digital Power MeterModel: SDM006Material: PCMeasurement Accuracy: 1% 2 digit. Display: 4pcs 0.32in red LED for AC voltage and power factor, 4pcs 0.32in red LED for active power and power frequency, and 5pcs 0.32in green LED for electrical energy. AC Voltage: AC 80-300VAC Current: AC 0-100A, the current display resolution is 0.01A when the measured current is less than 100A, 0.1A when the measured current is greater than 100A, and the range automatically switches. Active Power: 0.0-30000W of AC 80.0-300.0V measured voltage. Electric Energy: 0.000-999999kwhPower Frequency: 45.00-65.00 HzPower Factor: 1.000-0.000Measurement Speed: 2 times per second. Installation: DIN Rail TypeWorking Temperature: -10 ~ +60Working Humidity: 10~80%, no condensation. Working Pressure: 80-106kPaHow to Use: 1. Connect the measured voltage to the 1 and 2 wiring terminals at the bottom left of the instrument. 2. The built in transformer is wired, and the wires of the measurement circuit are threaded through the round hole below the instrument. The direction of the wiring can be selected by the user according to the usage situation. The direction of wiring can be either from the round hole below the instrument to the top or from the round hole above the instrument to the bottom. Different directions of wiring will not affect the measurement results. 3. After turning on the power, the measurement display functions displayed on the instrument are voltage V, current A, and active power W. The red LED indicator on the right side of the corresponding display window lights up to indicate the corresponding display function. 4. Press the button SAM CK on the right side of the dashboard to convert the three displayed functions into power factor cos , time accumulation h, electrical energy kWh, the green LED indicator light on the right side of the corresponding display window lights up, indicating the corresponding display function. 5. Press the button SAM CK again, and the display function of the instrument will be converted back to voltage V, current A, and active power W. 6. When it is necessary to reset the electrical energy measurement and timing, when measuring from 0, switch the measurement function to the electrical energy measurement function, and the green indicator light on the right side of the instrument display will light up. At this time, press and hold the button SAM CK for 5 seconds, until both the electrical energy and timing display are displayed as 0. Release the button, and both the electrical energy and timing display will start measuring from 0. Both the electric energy and timing displays can automatically saving data during power outages, that is, when the measurement voltage is disconnected or powered off, the instrument will automatically save the current test data. When the measurement power is reconnected, the instrument will continue to accumulate the saved data. No exposure to direct sunshine. .Package List:1 xDigital Power Meter1 x User Manual
