Features MULTI FUNCTION AND GOOD HEAT DISSIPATION --- With automatic memory function of all parameters, very suitable for automatic assembly of power adapter aging cabinet. The size is slightly larger, and the fan is upgraded to the original 5020 for delta high spee CLEAR DISPLAY AND SAFE --- The battery capacity tester display comprehensive and clear information. Equipped with intelligent CPU fans, can effectively dissipate heat silently TECHNICAL PARAMETERS --- Electronic load battery tester maximum power for 60W, maximum voltage 30V, maximum current is 9.99A. Overvoltage, overcurrent, and overvoltage alarms can effectively protect the module from damage PROTECTION FUNCTION --- The electronic load tester provides overheat protection otP, instantaneous overpower protection oPP, overvoltage protection ouP, reverse connection protection, and power voltage abnormal protection WIDE APPLICATION --- This multifunctional constant current electronic load can measure voltage, current, power, battery capacity, impedance, temperature, energy, time. Test various batteries, DC power supplies, charging data cables Specification: Item Type: Electronic Load Tester Material: PCB and aluminum alloy Working Mode: Constant current(CC) single mode Discharge Current: 0.20-9.99A step by 0.1A or 0.01A Maximum Discharge Current Error: 0.7%-0.01A Maximum Capacity Test Error: 0.5A 2.5%, 2A 1.5%, 5A and above 1.2% Off Line(termination) Voltage Range: 1.0-25.0V Step 1V or 0.1V Discharge Voltage: 1.00-30.00V Maximum Voltage Measurement Error: 1%+-0.02V Peak Power: 60W super power automatic limit maximum current(for example, maximum 9.99A 6V at 60W, maximum 20V at 3.00A alone) Maximum Battery Test Statistics: 999.9Ah or 9999Wh, reaching the stop value test (the first value of the stop condition) Positioning Hole Position: Approx. 60 x 88mm / 2.36 x 3.46in Diameter: Approx. 3.2mm / 0.13in, 5mm / 0.2in Base is installed I. Mode Setting (default factory is electronic load mode) : Press and hold the start stop button (small red button) and power the tester at the same time, release the button until Fun* is displayed, and change the setting by rotating the knob, "Fun1" is the electronic load mode, "Fun2" is the battery capacity test mode. Press the start and stop button to enter the buzzer setting, and also rotate the knob to set the "bEon" buzzer on or "bEoF" buzzer off. After the setting is complete, press the start and stop button again to restart the tester. Package List 1 x Electronic Load Tester
