Voltmeter range: DC 0.00-33.00V (resolution 0.01V) power supply, DC3.5-28V please do not overvoltage 2. Voltmeter range: DC 0.0-99.0V (resolution 0.1V) power supply, DC3.5-28V please do not overvoltage Ammeter range: DC 0-999.9mA-3.000A Automatically variable accuracy, minimum resolution below 1A 0.1MA, minimum resolution 1-3A 1MA. High precision and absolute cost performance. Display instructions: The digital tube above the meter shows the measured voltage, with a four-digit fixed display accuracy, a measurement range of 0-33.00V, and a minimum resolution of 10mV. The digital tube below the meter shows the measured current, with four-digit variable display accuracy. The measurement range is 0-3.000A. When the measured current is greater than 1A, the display accuracy is 1mA; when the measured current is less than 1A, the display accuracy is 0.1mA. . Voltage compensation function description: (note that the 0-99.9V version does not have this function) When the system carries a large load, there will be a certain voltage drop on the connecting line. At this time, the voltage measured by the meter will not correctly represent the output voltage of the system power supply. Use this voltage compensation function to compensate for the voltage loss on the connecting line. Moderate compensation can more accurately measure the output voltage of the system power supply. When using this voltage compensation function, you must prepare a ProductSiteLaunchDate : 2024-03-09T03:44:20.668Z Size : Red Green0-99.9V UnitCount : 1
