ITEM NAME:1 x ZB2L3 Lithium Lead-acid Battery Capacity Meter Discharge Analyzer Tester New Descriptio n Usage method: 1. The battery under test should be charged first. 2. Connect the positive pole of the tested battery to the input positive pole and the negative pole to the input negative pole. It is not possible to connect the negative pole to the input negative pole. Connect the load to the output positive and negative poles and turn on the micro USB power supply for the tester (no desktop or notebook USB power supply), then display the battery voltage. 3. The direct start-up test only needs to press the "OK" button. The tester can automatically set the appropriate termination voltage according to the full charge voltage of the battery, and it will flicker to display three times before starting the test. The termination voltage needs to be manually determined by pressing the button of'+'or'-' in the state of battery voltage display. The termination voltage is displayed at the beginning of P, and then represents the voltage value with a resolution of 0.1V. After setting, the test begins by pressing'OK'. 4. After the start of the test, the tester will turn on the electronic switch to control the load. The test process data show that it will rotate between the discharge capacity (Ah), the current discharge current (A) and the battery voltage (V). When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, and the display data stays above the capacity (Ah) and flickers quickly with the corresponding indicator. At this time, the display capacity is the actual discharge capacity of the battery. Pressing "OK" can stop flickering and make the data display stable and press again. "OK" button restored to the power-on state can replace the battery test next section... Error code and meaning: Err1: Battery voltage higher than 15V Err2: Battery voltage below set termination voltage Err3: Batteries can't withstand load discharge c.Pressing "OK" can stop flickering and make the data display stable and press again. The direct start-up test only needs to press the "OK" button. After setting, the test begins by pressing'OK'. Connect the positive pole of the tested battery to the input positive pole and the negative pole to the input negative pole.
