During use, do not work under high voltage above 20V, otherwise it will easily cause overvoltage damage to the product. 10A series products have shunt resistors, and the test terminal for DC measurement will be short-circuited. As long as the instrument is connected in series with the load according to the wiring diagram, it can be used normally. Working voltage: The working voltage of the instrument is DC 5-30V, and it is recommended to be 5-12V. The thin red wire is the positive pole of the working power supply, and the thin black wire is the negative pole of the working power supply, which is on the same ground as the thick black wire; the limit voltage connected to the red and black thin wires cannot exceed 24V, and a 12V power supply is recommended. Measurement range: The voltage measurement range is 0-100V, and the display mode below 10V is 0.0V. The voltage starts at 0.1V and has a tolerance of ±1V. The current measurement range is 0-10A, the current starts from 0.03A, and the error starts from ±3%. Shunt Resistor: On-board shunt resistor, no need for external shunt, just use it directly according to the wiring diagram.
