Open the package, insert the power adapter into the end of the product and supply the power.\n2. Anti-clockwise rotate the two current knobs to the lower limit.\n3. Connecting the Power Supply under test to the product according to the diagram above, and the current input voltage value will be read out. Keep pressing the for key to reset all data to zero;\n4. Slowly clockwise rotate the two current knobs (coarse&fine) to adjust the current to the rating value of the Power Supply(The current should be slowly adjusted, using the fine knob priority, the coarse knob could be only used under large current condition.)\n5. When testing the battery, Low voltage discharge limit should be set up, to avoid the possible damage caused by over discharging while discharge capacity test of the battery.\n \nNote:\nEU plug, please pay attention before placing an order.\nNo retail package.\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x Electronic Load Tester"]
