I. Operating Methods:
Connect the DC or AC power cord to the rear side of the testing instrument and turn on the tester, which will light up the LCD screen.
Connect the test cable and communication cable to the front side of the tester (if not connected to software, the communication cable is not needed). During the general testing process, alligator clip wires, four-wire battery holders, or USB male cables will be used for testing batteries with poles, cylindrical batteries, and power banks/power supplies. To ensure sampling accuracy, the test clamp wire uses a four-wire system, with the red wire connected to the positive terminal of the battery and the black wire connected to the negative terminal. The thick wire is for current collection (A+A-), and the thin wire is for voltage collection (V+V-). The test cannot be conducted if only the thick or thin wire is connected.
Connect the battery or power source to be tested to the front side of the tester, and the current voltage will be displayed on the tester's LCD.
Enter the settings interface by pressing and holding the SET button/knob, and set the test parameters using the buttons or knob. When connected to a computer, the buttons and knobs will become inactive, and settings can be made directly through the software on the computer.
To accurately measure the battery capacity, a constant current discharge test is generally required for a fully charged battery. Set the discharge current and cut-off voltage, and the final capacity will be displayed on the LCD screen. The capacity test for power banks is the same, and specific parameter settings can refer to "Frequently Asked Questions and Solutions."
Testing the current of a power bank or power supply also involves constant current discharge. The discharge current can be set to the maximum output value of the power bank or slightly less, with the cut-off voltage set to below 4V. It is particularly important to note that the cut-off voltage does not refer to the output voltage of the power bank, but rather the voltage at which the test stops. The tester uses the set cut-off voltage as the criterion for determining when to stop the test. Start the discharge with a small current, and then gradually increase the current through the buttons/knobs or software after starting. When the current is adjusted to a certain value and the power bank stops outputting, the maximum value has been measured.
After setting up, you can proceed with the specific testing. After the test, the results will be displayed on the LCD or software. It is particularly important to note that if the test is initiated through the software and the software communication is disconnected during the test, the software will not be able to collect any data after the disconnection and can only view the data displayed on the LCD screen after the test is completed.
After the test is completed, strictly follow the steps to remove the tested battery or power source first, and then turn off or disconnect the power supply of the tester.
