Multifunctional AC Voltage and Current Meter AC40-300V 100A Color LCD Digital Display Power Monitor 100A

The D69-2049 multi-function digital multimeter simultaneously displays the measured AC voltage, AC current, active power, electrical quantity, and electrical energy. The display features a high-definition color liquid crystal display with a 178° wide viewing angle.

Instructions for Use and Main Technical Indicators

1. Measurement accuracy: 1% ± 2 digits

2. Measuring range: AC voltage: AC40.0-300.0V (users can select a suitable range according to their needs when ordering)

AC current: AC0-99.99A, the current display resolution is 0.01A, when it exceeds 100A, it will display 100.0A

3. Active power: 40-300V, display range 0-30000W, 200-450V, display range 0-45000W, the display resolution between 0-9999.9W is 0.1W, [the rest is 1W]

4. Power: Display range: 0-10000KWH displays 9999.999, above 10KWH displays 00000.99KWH, maximum display 9999999KWH

5. Measuring speed: 2 times per second

6. Dimensions: 79*43*48mm

7. Installation size: 76*39mm

8. Save/memory function: When the power is cut off during the use of the meter, the accumulated electricity value of the meter will be automatically stored (the previous electrical data will not be lost)

9. (100A transformer hole diameter 15.5mm) can meet the national standard of 21-25mm² (mm) standard copper wire passage

10. The lead wire of the secondary end of the transformer can be extended by about 0.5 to 3.5 meters depending on the installation distance of the equipment (0.3 meter square wire or ordinary light bulb wire can be used without affecting the measurement accuracy).

How to Use and Connect

1. Connect the secondary end (green wire) of the current transformer supplied with the instrument to the blue terminal of the instrument and pass the measuring loop wire through the center round hole of the current transformer.

2. Connect the voltage measuring cable to the green terminal of the meter, then measure the voltage as above and start reading the measurement results.

3. After the power is turned on, the instrument displays the measured value.

4. Press and hold the reset button on the front panel of the meter for 5 seconds to reset the accumulated power value of the meter to zero.

5. Extreme Working Conditions:

Operating Temperature: -10～+50℃

Operating Humidity: 10-80% (non-condensing)

Working Pressure: 80～106kPa

Sunlight Exposure: No direct exposure

Precautions

1. To measure the mains voltage (110V AC to 220V AC), please check the voltage between 40 and 300V AC. To measure the mains voltage (380V AC), please check the voltage between 200 and 450V AC. If you check AC200-450V when placing an order, the voltage measuring instrument for 220V network is inaccurate! Remember!

2. The wiring of the voltage input terminal (green) and the current transformer secondary input terminal (blue) must not be connected incorrectly, otherwise the instrument will be damaged!

3.AC200-450V is only suitable for pure AC 50-60HZ mains power supply and cannot be used for measurement on square wave inverter output and corrected sine wave circuit, otherwise the instrument will be permanently burned out!

4.AC80-300V can be used for measurement on non-positive wave selection circuits [such as: square wave and modified wave inverters, frequency converters, variable frequency soft-start motors and other equipment]

5. When installing the instrument, be careful not to press the LCD display! Otherwise, the code may be illegible or distorted.
