It can only measure and display the voltage, current and power of the circuit under test. The displayed value can be fine-tuned with an adjustable resistor. The actual voltage and current of the loop has no effect. _x000D_ Do not use high voltage above 30V when using, otherwise it will cause overvoltage damage to the product. _x000D_ 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. _x000D_ The 50A/100A series products require an external shunt to function properly. When the shunt is connected, the test terminals are shorted and the current is measured directly. As long as the instrument is connected in series with the load according to the wiring diagram, it can be used normally. _x000D_ According to different current ranges, it is divided into 10A, 50A, 100A. _x000D_ Operating Voltage: _x000D_ The working voltage of the instrument is DC 4-30V, and 5-12V is recommended. _x000D_ 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 belongs to the common ground with the thick black wire; _x000D_ When in use, the limit voltage connected to the red and black thin wires cannot exceed 30V, it is recommended to use a 12V power supply _x000D_ _x000D_ Note: _x000D_ Temperature display requires self-soldering temperature sensor. _x000D_ The 50A/100A must be connected to an external shunt for use. _x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1 X Voltmeter _x000D_ 2 X Power Load Cords _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
