Describe

The D48-2058 digital multifunction meter can simultaneously measure and display 6 parameters such as AC voltage, AC current, active power, power factor, frequency and electric energy. The display part of the instrument adopts a color high-definition liquid crystal display.

Specification

1. Measurement accuracy: 1% ± 2 words

2. Measuring range: AC voltage: AC50.0-300.0V, (or AC250.0-450.0V), the user can choose an appropriate range according to his needs when ordering)

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

Power frequency: 45.0Hz-65.0Hz

Power factor: 0.00-1.00PF

Active power: the measurement range is 0-45000W, the display resolution between 0-9999.9W is 0.1W, and the rest is 1W

Electricity: The measurement range is 0-99999kwh, the minimum display resolution of 0-999.99kwh is 0.01kwh 10000.0-9999.9kwh, the minimum display resolution is 0.1kwh,

The minimum resolution of 10000.0-99999kwh is 1kwh

3.Measuring speed: about 2 times per second

4. Dimensions: 49×47×52(mm)

5. Hole size: diameter Φ22mm

6. Save function/memory function: automatic save function: when the power is off, the meter will automatically save the current energy value, and the meter will read the value after the next power on, and continue to accumulate.

Use and wiring method

1. Connect the wires according to the wiring diagram in the attached drawing, and insert the two-wire plug of the secondary end of the current transformer of the instrument into the secondary input end of the instrument. Pass the main loop wire of the current test through the middle round hole of the current transformer.

2. Connect the voltage measuring lead to the measuring voltage input terminal of the meter. Then turn on the measurement voltage. Start reading the measurement results.

3. The power reset button of the meter is on the lower right side of the meter. When power reset is required, use a circle with a diameter of less than 2mm and gently press it in the reset hole for 5 seconds to reset the cumulative value of power.

Precautions

The 250-450V range meter is only suitable for pure AC 50 mains power. It cannot be used for square wave, inverter output and modified sine wave circuit measurement, otherwise the meter will be damaged. The 50-300V range meter is not affected.
