Product details ZB2L3 battery capacity tester discharge type 1.2-12V external load capacity of the battery and other tests 18650 Tools, single-function, by controlling the load off and getting real-time integrated discharge current capacity results Maximum support 15V 3A discharged through the discharge voltage and the current, itself does not discharge Maximum capacity statistics support 9999Ah (9999000mAh) Automatically identify and develop appropriate battery termination voltage can also be manually adjusted Specifications Power supply voltage: DC4.5-6V (micro USB connector) Operating Current: less than 70mA Discharge voltage: 1.00V-15.00V 0.01V resolution Termination voltage range: 0.5-11.0V Supported by current: 3.000A 0.001A resolution Maximum voltage measurement error: 1% 0.02V Maximum current measurement error: 1.5% – 0.008A Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above, to achieve 10Ah XX.XX, and so on. Board size: 50mmX37mm Finished Size: 50mmX37mmX17mm (length X width X height maximum position size, contains copper foot height) Instructions The first test should be a fully charged battery. Connect the battery to be tested positive to positive input, a negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the output of the positive and negative output, to work through the tester micro USB power supply (not available desktop or laptop USB powered), then the battery voltage. Direct start test needs only one press of the “OK” button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing “ ” or “-” buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the “OK “start testing. After the start of the test the tester will control the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A), and battery voltage (V) between the wheel was. When the battery voltage reaches the set cut-off voltage, the load control switches off the tester display data stays in capacity (Ah) and above, and the corresponding indicator flashes quickly together, now displays the actual capacity of the battery is discharging capacity, about the press “OK” to terminate flashing allows stable data display, press again “OK” button to return to the power-on state can just replace the battery test the next section …… Error codes and their meanings Err1: battery voltage is above 15V Err2: The battery voltage is lower than the termination voltage Err3: The battery can not afford to load or discharge the current line with too much resistance Err4: overcurrent (current exceeds 3.1A) Note: Use the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety! This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminals (absolute 0V) will show 0
