Digital Single Phase Energy Meter Tester Electricity Usage Monitor Ampermeter Power Voltmeter Ammete

Feature: 1. One Touch Data Switching: This meter can display the measured AC voltage, current, accumulated time and frequency. The red and green LEDs help you to get the numbers easily. When the SAM CK key is pressed, the meter will change the display and the corresponding red LED will light up. 2. 1% Measurement Accuracy: This single phase energy meter is safe to use with excellent PC flame retardant material and accurate chip. The accuracy is 1% ± 2 digits, and the measurement speed is twice per second. 3. Simultaneous Display Of AC Voltage And Current: DIN rail AC voltage and current meters can display AC voltage and current simultaneously. For currents below 100A, simply pass the wire through the hole on the right side of the meter to obtain the AC current. 4. Data Storage And Zeroing: While the meter is displaying electrical energy, you press and hold the SAM CK key for 5 seconds and the meter will reset. The meter will automatically save the electric energy value and the accumulated time electric energy value when the power is disconnected, and the meter will continue to accumulate data when the measurement power is turned on again. 5. Wide Application: This AC power meter rail with built in transformer can meet the maximum load current of 100A. It can be used in schools, shopping malls, homes, industries, laboratories, etc. Specification: Item Type: Multifunction Detection Energy Meter Model: SDM007 Material: PC Measurement Accuracy:1%±2 Word Display: AC voltage use 0.32 inches four red LED, AC current use 0.32 inches four green LED, working time and voltage frequency use 0.32 inches of five red LED AC Voltage: AC80-300V AC Current: AC0-100A Electricity Power: 0.000-99999kwh Power Frequency: 45-65HZ Measurement Speed: 2 x/s Pressing Method: DIN Rail Type Working Temperature: -10-+60℃ 140℉ Working Humidity: 10-80% ( Without Condensation ) Working Air Pressure: 80-106kPa Operating Instructions: 1. Connect the measured voltage to the 1 and 2 terminals on the lower left side of the instrument. 2. Wiring the built in transformer according to the wiring diagram, the measurement circuit wire through the round hole below the meter, the direction of the wire penetration user can choose according to the use of the situation, you can penetrate the round hole from the bottom of the meter to the top out, or from the top of the meter to the bottom out of the round hole, penetration direction is not the same will not affect the measurement results. 3. After the power is turned on, the measurement display functions of the meter are voltage (V), current (A), active power (W), and 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 meter panel, the three display functions will be converted to power factor (cosΦ), time accumulation (h), and electric power (kwh), and the green LED indicator on the right side of the corresponding display window will light up to indicate the corresponding display function. 5. Press the button (SAM CK) again, the display function of the meter will be converted to voltage (V), current (A) and active power (W) again. 6. When you need to measure the electric energy and timing reset (from zero measurement), the measurement function will be converted to the electric energy measurement function, that is, the right side of the meter display green indicator lights up, then press and hold the button (SAM CK) for 5 seconds (press and hold for 5 seconds) until the electric energy and timing of the two displays are displayed as 0, release the button, then the electric energy and timing of the two displays are measured from zero. The two displays of power and timing have the function of automatic data saving in power failure, that is, when the measurement voltage is disconnected or power failure, the meter will automatically save the current test data, and when the meter is reconnected to the measurement power, the meter will continue to accumulate on the original saved data. Sunlight exposure: No direct exposure. Package List: 1 x Multifunction Detection Energy Meter 1 x Manual Note: This meter is only suitable for pure AC 45‑65Hz mains power supply, it cannot be used to measure on inverter output, modified sine wave and other circuits, otherwise the meter will be damaged.
