Feature: 1. Original IR power tube, dual NMB ball bearing high speed fan, with temperature control stepless variable speed function, with industrial large tooth radiator, can ensure long-term operation stability. 2. Classic digital tube display, intuitive and durable, more resistant to high temperature than LCD. 3. Rotary encoder setting, simple operation and diverse functions. 4. Buzzer sound prompt, high operating experience. 5. With all-parameter automatic memory function, very suitable for assembling power adapter automatic aging cabinet. 6. Leave factory after 100% power aging test. Specification: Item Type: Electronic Load Aging Battery Capacity Tester Module Working Mode: Single mode constant current (CC) Discharge Current: 0.20-9.99A, Step 0.1A or 0.01A Maximum Discharge Current Error: 0.7%-0.01A Maximum Error in Capacity Test: 0.5A 2.5%, 2A 1.5%, 5A and above 1.2% Maximum Power: 60W, exceed power automatically limits the maximum current (for maximum 60W, it can open 9.99A at 6V and at most 3.00A at 20V) Highest Statistical Value of Battery Test: 999.9Ah or 9999Wh, reach the value to stop the test Positioning Hole Position: 60mmx88mm Hole Diameter 3.2mm Load Power Supply: 12V, current 0.5A or more Fan Control: Intelligent fan control (Fan can automatically change the speed according to the radiator temperature) Instructions: 1. Mode Setting (default is factory electronic load mode): Press and hold the start and stop button (small red button) to power on the tester at the same time, until the display of Fun*, release the button, change the setting by turning the knob, “Fun1” is In electronic load mode, “Fun2” is the battery capacity test mode. Press the start and stop button to enter the buzzer setting. Also set the “bEon” buzzer to turn on or the “bEoF” buzzer to turn off by turning the knob. After the setting is completed, press the start and stop button again to restart the tester. 2. Electronic Load Mode: 1. Turn on the 12V working power supply and enter the electronic load mode to ensure that it is in the stop state ("RUN" light is not lit, otherwise press the start/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 do not take the wrong! Note: When in the alarm state, the current can only be turned down and cannot be turned up! The tester automatically saves the power and saves the set parameters and the running status. When the power is turned off again, the status and data before the power failure will be completely restored. 3. Battery Capacity Test Mode: 1. The battery to be tested should be fully charged with a dedicated charger! Additional Instructions: 2. The tester power-off automatic save can record the set parameters, and record all the parameters and status when the test process and the test completion alarm state are powered off, and all the automatic recovery after re-power transmission. Fault Protection Code and Meaning: Err3: The internal resistance of the circuit is too large or the battery cannot withstand the set discharge current. Err4: Circuit failure. Err6: The working power supply is not suitable. Please use the standard 12V regulated power supply, and the power supply current should be no less than 0.5A. otP: Overheat protection. Ert: Temperature probe is faulty or the temperature is too low. oPP: The instantaneous power is too high in the electronic load mode. .
