Features 1、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 speed double bearing fan, which has higher heat dissipation redundancy and is more suitable for long term work 2、CLEAR DISPLAY AND SAFE: The battery capacity tester display comprehensive and clear information. Equipped with intelligent CPU fans, can effectively dissipate heat silently 3、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 4、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 5、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% 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. Ii. Electronic Load Mode: 1. Turn on the 12V working power supply and enter the electronic load mode, ensure that it is in the stopped state (the "RUN" light is off, otherwise press the start and stop switch to turn off the load), connect the tested power supply to the test input power port (P+P-), pay attention to the polarity is not wrong! Note: When in the alarm state, the current can only be turned down can not be turned up! The automatic power failure saving function of the tester can save the set parameters and operating status. After power failure, the status and data before power failure will be completely restored. Iii. Battery Capacity Test Mode: 1. The tested battery should be fully charged with a special charger first! Additional Note: 2. The automatic saving of the tester power failure can record the set parameters, and record all parameters and states when the power failure occurs during the test process and the alarm state at the end of the test, and all will be automatically restored after re powering. Fail Safe Code And Meaning: Err3: The internal resistance of the line is too large or the battery cannot withstand the set discharge current. Err4: The circuit is faulty. Err6: The working power supply is not suitable. Please use the standard 12V regulated power supply with the power current not less than 0.5A. OtP: Overheat protection. Ert: The temperature probe is faulty or the temperature is too low. OPP: Instant super high power in electronic load mode. Package List 1 x Electronic Load Tester
