2. Voltmeter range: DC 0.0-99.0V (resolution 0.1V) power supply, DC3.5-28V do not overvoltage

Ammeter range: DC 0-999.9mA-3.000A Automatic variable accuracy, minimum resolution of 0.1MA below 1A, minimum resolution 1MA of 1-3A. High precision and absolute price/performance ratio.

Display instructions:

The digital tube above the meter head shows the measured voltage, four fixed display accuracy, the measurement range is 0-33.00V, and the minimum resolution is 10mV.

The digital tube below the meter head shows the measured current, four-digit variable display accuracy, measuring range 0-3.000A, when the measuring current is greater than 1A, the display accuracy is 1mA; when the measuring current is less than 1A, the display accuracy is 0.1mA .

Onboard wire function description:

Fine red line (VCC): power supply input positive (3.5-28V)

Note: If the measurement signal is lower than 28V and the power supply is sufficient, it can be directly used as the power supply for the module (use the thin yellow line and the thin red line in parallel)

Thin black line (GND): power supply input negative (3.5-28V) and measurement signal Fine yellow line (VIN): measuring voltage signal positive (0-33.00V)

Thick red line (I+): measuring device negative (must be connected in series between the negative pole of the power supply and the negative pole of the load)

Thick black line (I-): negative power supply (must be connected in series between the negative pole of the power supply and the negative pole of the load)
