Feature:
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

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!
2. Set the current and lower voltage through the knob, rotate the knob to set the value of the current setting position, press the knob to switch the setting digit, the two digital indicators in the middle of the digital tube and the V-A indicator on the right side of the digital tube to determine the current setting position.
3. Press the start-stop switch, the load starts to RUN, and "RUN" lights up. The circuit applies the set discharge current to the input power supply under test, and displays the actual input load voltage upstream.
4. The current can be modified at any time during the test process. If the lower voltage needs to be modified, the load needs to be stopped before it can be modified.

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!
2. Power on the tester to enter the battery capacity test mode, and connect the positive and negative terminals of the battery current line to the P+P- terminals. If the four wire fixture test is used, please connect the positive and negative terminals of the four wire fixture voltage test port to the V+V- port.
3. Set The Discharge Current And Discharge Termination Voltage By Rotating the knob (refer to II: 2 description for specific methods), after the setting, press the start and stop switch, the tester first detects the battery and the line, automatically identifies 2-4 lines (2 line identification shows JS-2, 4 line identification shows JS-4, if the display is wrong, please stop the test and check the wiring), and then enters the test, if there is a fault code, please refer to the following description.
4. During the test process, the upstream digital tube will wheel display the battery voltage, current discharge capacity Ah and current discharge en
