It is better than other electronic load with single chip built-in AD sampling digital tube display or battery capacity tester. Supporting user second correction of parameters, it is a best choice for DIY users. Features: 1602 LCD screen, display information comprehensively. Configuration of 9cm CPU fan, very quiet. With temperature display, supporting the discharge and voltage setting. Test all kinds of power load or burn-in, can also test capacity of battery discharge. Load maximum power 150W, maximum voltage 60V, maximum current 10A. Specifications: Voltage: DC 12V5% Load Type: Constant current Load Voltage: 0.5-60V Load Current: 0-10A Maximum Power: 150W Voltage Reading Precision: (0.1%+0.05%FS) Current Reading Precision: (0.2%+0.1%FS) Constant Current Accuracy: Current reading Precision + 1d Noise: 25dD(A) Weight: 341g(approx.) Instruction: Wiring Diagram of 2 Wires (Safe and convenient): Note: 2 wires must be respectively connected to A+ and A-. V+ is connected to A+, and V- is connected to A-. Wiring Diagram of 4 Wires: Note: 4 wires must be connected completely before use. 4 wires can offset voltage drop caused by electric wires under large current and ensures a more accurate voltage measurement. It is recommended if you are a professional. 4 wires must be all connected correctly before you power on the load. Wrong wiring is likely to cause damage, please make sure the wiring is correct! As you can see in the picture, there are thick wires and thin wires. The thick wires are for current, the thin wires are for measuring voltage, and of course you can use thick wires for all. Below is the operation interface. The operation is very simple and easy(when it displays "ON", it must be connected to load, otherwise it will beep and won't work) Bottom left screen corner will display information that automatic switching between power, AH, temperature, time, and can be set to always display certain one. "I": Setting load current "V": Setting discharge cut-off voltage. 1, the power adapter: DC 12V, load power and power supply should be 2 independent power. 2, Power on and screen shows "Welcome to use" which means equipment is normal 3, Press "set" to move the cursor, add and subtract operations according to the cursor position. When the cursor position is at "I" or "V", press "add" or "subtract" button to switch current and voltage setting. 4, Connect to power source that need to be tested, and make sure the wiring is correct. 5, Press "start" button to start/stop electronic load, and screen shows "ON" or "OF" 6, Press and hold "start" button for more than 1 second to reset AH and time, and power off the electronic load (if it was powered on) 7, The bottom left screen corner will display information that automatic switching by default every 2 seconds between power, AH, temperature, time. Press and hold "set" button, then press "add" button to switch, and the display information will not switch automatically. If you need the information to switch automatically again, press and hold "set" button, then press "subtract" button till bottom right screen corner shows "Auto". 8, Settings will be automatically saved after power failure. Electric loaf need to be manually started when power is back. 9, Continuous operation power of load is associated with operating temperature. When temperature is too high, operation power should be reduced. If the heat sink temperature reaches 87 , the load will automatically reduce power. When the core temperature reaches 91 , it will stop work, and need to be manually started after cooling. 10, Load current will be automatically adjusted according to the input voltage. For example, if set 10A, and the input voltage is 20V, then it automati
