Digital Energy Meter Tester, 40-300V 100A Ammeter Voltmeter Watt Kwh Meter

Technical Indicators: 1. Accuracy: 1% ±2 words 2. Range: AC Voltage: AC 40.0-300.0V or AC 250.0-450.0V (Select meter type in your order) AC Current: 0-100.0A, with a current resolution of 0.01A Frequency: 45.0Hz - 65.0Hz Power Factor: 0.00-1.00PF Electric Power: 0-450,000W, with a resolution of 0.1W for power between 0-9999.9W, otherwise the resolution is 1W Electric Energy: 0-99,999kWh, with a resolution of 0.01kWh for energy between 0-999.99kWh, a resolution of 0.1kWh for energy between 1000.0-9999.9kWh, and a resolution of 1kWh for energy greater than 9999.9kWh 3. Speed: 2 times per second 4. Size: 54×80×64 5. Installation: DIN rail

Application Procedure: 1. Connect the measuring voltage to terminals 1 and 2 2. For a meter with internal current transformer, follow diagram 1 and pass the wire through the hole in the meter 3. For a meter with external current transformer, follow diagram 2 and pass the wire through the hole in the meter, and connect the two wires from the secondary transformer to terminals 3 and 4 4. When the meter is switched on, it will display the measurement parameters 5. Press and hold the SAM CK button for 5 seconds to zero the electric energy, which will start accumulating when the button is released. The meter will store the value of electric energy when the power is off, and accumulate the data when the meter is turned on again

Attention: The meter can only be used to measure 45-65Hz AC city power

✅【6 Display Parameters】The power meter has a color LCD HD display that shows 6 different measurements simultaneously: voltage (40-300V), current (0-100A), electric power (0-30,000W), energy (0-9999kWh), frequency (45-65Hz), and power factors (0-1PF) ✅【180 Degree Wide Viewing Angle】The color LCD display offers a 178° wide viewing angle with no blind spots, providing clear visibility day and night. The backlight function enhances visibility in low-light conditions ✅【Reset Button】The electric watt meter features a reset button. Pressing it for five seconds will reset the digital electricity meter ✅【Automatically Save】The electric energy and accumulated time are automatically saved when the power is turned off. When the measuring voltage is reapplied, the data continues to accumulate, ensuring accuracy and convenience ✅【Note!】Please note that this multimeter is only suitable for measuring 50/60Hz AC power in the city. It should not be used to measure square waves and non-standard sine waves, as it may cause damage.
