Three integrated capacity measurement modes are available:
1. Two-wire intermittent mode – Cutting off the discharge current instantly to detect the battery voltage to prevent the influence of line loss, this mode is to test the terminal voltage at the moment of load cutting (within a few milliseconds) rather than the loaded voltage.
2. 2-wire continuous mode – mainly used as electronic load test power supply, the mode is to test the loaded terminal voltage.
3.Professional 4-wire test mode – need to cooperate with special fixture to accurately test the battery performance, this mode is to test the BV terminal differential voltage.
The current version has independent RES-V (battery resistance-voltage test) function! (This function is suitable for fast sorting of batteries with internal resistance above 20mΩ, low internal resistance power batteries are not suitable, the pulse method of testing is not the working principle of standard AC internal resistance meter).

Quick start using instructions:
1. Connect the positive and negative terminals of the fully charged battery under test (rechargeable battery) to the blue terminals of BAT+ and BAT- respectively, and connect the wires as short and thick as possible! Give the tester through the DC 12V working voltage (microUSB models use 5V power supply), the tester power on to display the discharge current.
2. Press the S–or S++ button to change the setting current within the range of 0.1-2.6A, after the current is suitable, press the SK button to start the test (such as fault code Err*, please refer to the back of the content), the tester is able to intelligently select the type of battery and formulate the termination voltage, after the start of the test, "RUN" indicator lights up, the digital tube displays "RUN", the tester will display "RUN". After starting the test, the "RUN" indicator light will be on, and the digital tube will display the values from capacity Ah, energy Wh, voltage V and current A in turn. When the test is completed, the digital tube stays at the Ah value and flashes rapidly with a sound reminder, and the "RUN" indicator goes out.
3. After the completion of the test, you can press the "SK" button to stop the tester flashing alarm, you can also press the S–or S++ button to switch to view the battery capacity Ah, energy Wh and discharge platform voltage V, when you press the "SK" button again, the tester returns to the power-on current setting. When pressing the "SK" button again, the tester will return to the state of power-on current setting, and you can repeat the previous operation for the next battery test.

Note: The backup data will be cleared only when the test is finished and the alarm is activated, if not, the backup result will always be saved and will not be cleared even if the power is cut off!

Error Code Err* Meaning and Handling:
Err1: Battery voltage is too high, please make sure the battery voltage is lower than 8.5V before testing.
Errr2: Battery voltage is too low (lower than the set termination voltage value), please confirm the battery voltage and reset, if the battery is connected to the opposite side and the 4-wire mode voltage measurement is not connected or connected to the opposite side, Errr2 will also appear.
Err3: The battery does not support the set discharge current or the internal resistance of the line is too large, please use a smaller current to test the battery and make sure that the battery line is thick and short and the contact between the electrodes is good.
Err4: the power tube is damaged, this problem usually occurs after the bad transformation, you can replace the power tube by yourself, the substitute model is P75NF75 and so on.
Err5: Exceeding the test power limit, the state may only appear when the power limit function is on (LPon), representing the set conditions under the power over 12W, the tester to prevent overheating and take protective measures! Users can make modifications by themselves (increase the heat sink or install a fan) and enter the function setting menu to turn off the power limit (LPoF), so that the power can be used over 12W.
Err6: Power supply voltage is out of range, when the power supply voltage is lower than 11V or higher than 14V, the tester will display this error code during the power-up process, please replace the power supply with a suitable voltage!

Note: When Err1-Err5 is displayed, press any key to return to the initial state.
