ZB2L3 18650 Battery Tester LED Digital Display Module
Tscinbuny ZB2L3 Battery Tester LED Digital Display 18650 Lithium Battery Power Supply Test Resistance Lead-acid Capacity Discharge Meter Description:100% brand new and high qualityMaterial: Electrical componentsZB2L3 battery capacity tester discharge type 1.2-12V external loadcapacity of the battery and other tests 18650Tools, single-function, by controlling the load off and getting real-timeintegrated discharge current capacity results.Maximum support 15V 3A discharged through the discharge voltageand current, itself does not discharge.Maximum capacity statistics support 9999Ah (9999000mAh)Automatically identify and develop appropriate battery terminationvoltage can also be manually adjusted. Specifications:Power supply voltage: DC4.5-6V (micro USB connector)Operating Current: less than 70mADischarge voltage: 1.00V-15.00V 0.01V resolutionTermination voltage range: 0.5-11.0VSupported by current: 3.000A 0.001A resolutionMaximum voltage measurement error: 1% + 0.02VMaximum current measurement error: 1.5%+- 0.008AMaximum battery capacity range: 9999Ah (1Ah = 1000mAh) greatervalue by shifting the decimal point to switch, when the display is lessthan 10Ah X.XXX, as shown above, to achieve 10Ah XX.XX, and so on.Board size:50mmX37mmFinished Size: 50mmX37mmX17mm (length X width X heightmaximum position size contains copper foot height). Instructions:1. The first test should be a fully charged battery2. Connect the battery to be tested positive to positive input, anegative input to the negative, can not be reversed (with load reversalmay damage the circuit)! Load connected to the output of the positiveand negative output, to work through the tester micro USB powersupply (not available desktop or laptop USB powered), then the batteryvoltage.3. Direct start test needs only one press of the "Ok" button, the testercan automatically develop an appropriate termination voltage for thebattery full charge voltage, and will start flashing after the test threetimes. Need to develop artificial termination voltage only when thebattery voltage display state by pressing "+" or "_buttons to modifythe termination voltage display beginning with P, behind therepresentative voltage resolution 0.1V, set up after pressing the "OKstart testing.4. After the start of the test the tester will control the load of thethe electronic switch is turned on, the test data shows that the processwill release capacity (Ah), current discharge current (A), and batteryvoltage (V) between the wheel was. When the battery voltage reachesthe set cut-off voltage, load control switches off the tester display datastays in capacity (Ah) and above and the corresponding indicatorflashes quickly together, now displays the actual capacity of the batteryis discharging capacity, about the press "OK" to terminate flashingallows stable data display, press again "Ok" button again to return to thethe power-on state can just replace the battery test in the next section ...... Error codes and their meanings:Err1: battery voltage is above 15VErr2: The battery voltage is lower than the termination voltageErr3: The battery can not afford to load or discharge the current line too muchresistanceErr4: overcurrent (current exceeds 3.1A)Note: Use the resistance of the discharge process, resistive load willseriously heat, please pay attention to safety!This circuit voltage to improve the measurement accuracy,specially designed DC bias, when the terminal displays nothing thena small voltage does not affect the actual measurement, if you areshorting the input terminals (absolute OV) will show 0
