There are three intelligent safety protections in the discharge detection process, which can monitor the state of the discharge tube in real time, safe and reliable. External wired NTC thermometer can realize internal and external dual temperature measurement. 2. Digital Display: 2.4in high definition large color screen electronic tube digital load meter. Intelligent temperature controlled colorful fan, quick in heat dissipation. 150W high power, 200V wide voltage, 20A high current, strong performance. 3. Extensive Using: Supports testing for Android, Type C cable, Mini and other wires, and displays various test data on one screen. Through inspection and testing various data cables, charger tests, discharge aging, DC power adapter current, voltage, power and other parameters, the operation is simple, convenient and fast. 4. A Useful Tester: 150W load discharge aging test adopts built in large discharge tube, and the temperature is maintained at about 50-80 ℃. Easily test the voltage, current, capacity and other data of various power supplies such as lithium battery and USB charger. 5. Easy to Install: Comes with a light weight and a compact size as well, the electronic load tester is very convenient to install within minutes. Specification: Item Type: Electronic Load Tester Material: ABS Plug: US Plug 100-240V Test Voltage: 2-200V Working Current: 0.2-30A Constant Load Adjustment Rate: ± 3% + 3 bytes Discharge Power: Voltage x current < 150W. How to Use: 1. Quick Application of Constant Current Discharge Mode: Insert the power adapter in the packaging box into the power input port at the end of the product. The product will light up when connected the measured power supply. The display screen will show the current measured input voltage value. Short press the setting key, the cursor under the constant current number will move left and right, and then short press the plus and minus keys to adjust the corresponding value to the discharge current value you need, and then press the start button, the display shows ON and start constant current discharge and capacity energy accumulation and timing. If you need to set the time limited discharge time and stop voltage value, please press and hold the setting key once when the discharge is stopped, CC on the display interface will start to jump, and then press and hold the setting key briefly to move to the time limited discharge column, and the value will flash. Press and hold the plus and minus keys to adjust the jump value. After setting, press and hold the start key to save for confirmation or wait for the flashing stop to save automatically. 2. Application of Constant Resistance, Constant Power and Constant Voltage: When the product is powered on and no discharge, long press the setting key, and the CC on the display interface will start to jump. At this time, short press the plus and minus keys to adjust the CR CP CVCC several mode cycle display, select the corresponding function mode, wait for the flashing to stop, and then the system will save and enter this function mode. You can also use the same application as the constant current discharge mode to adjust and turn off the discharge. 3. Battery Capacity and Power Detection: First fully charge your battery to be tested, then long press the start key to enter the background to reset the accumulated data and exit the background, then long press the setting key CC to start flashing, short press the setting key to set the minimum battery discharge voltage in the stop voltage column, then short press the start key to save, then set the rated discharge current value, and short press the start key to start measuring the accumulated battery capacity value. When the discharge is aged to the battery stop voltage value you set, the system will display the word COMPLETE, indicating that the capacity test is completed. At this time, the capacity MAH and the capacity WH values on the display screen are the capacity and capacity values of the battery. 4. Detection of Output Voltage, Current Value and Maximum Power Value of DC Power Adapter: Connect the output of the power supply to the product, display the current voltage value, and then set the nominal current value of the power supply to be tested to the machine, and turn on the load for discharge aging for 3-6 hours. During the process, the temperature of the power supply to be tested is not high and the voltage is stable, which means that the quality of the power supply to be tested is stable, and the nominal value is accurate without error. During the ON discharge process, short press the +/ button to increase the current to the moment when the voltage of the tested power supply drops and the voltag
