    ZB2L3 Battery Capacity Tester External Load Discharge Type Module-Module Board

    ZB2L3 Battery Capacity Tester External Load Discharge Type Module 1.2-12V 18650 Battery Available Note: Using the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety. Please install the 50W aluminum resistance (has been soldered half part of high temperature line) to a metal plate to use. This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal connects nothing will display a small voltage, but does not affect the actual measurement, if you are shorting the input terminal (absolute 0V) will display 0. If you want to know the principle, you can check the superposition theorem of electrical engineering. Specification: 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 current: Maximum 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 is switched by shifting the decimal point, when it is less than 10Ah will display X.XXX, up to 10Ah or more will display XX.XX, and so on. Board size: 50 x 37mm Finished size: 50 x 37 x 17mm (L x W x H maximum position size, contains copper foot height) Board net weight: 28g (including pillars) Resistor weight: about 27g (including cable) How to use: 1. The test battery should be fully charged. 2. Connect the battery positive to positive input, negative input to the negative, can not be reversed (with load reversal may damage the circuit). Load connected to the positive output and negative output, power on the tester with micro USB power supply (not available desktop or laptop USB powered) then the battery voltage display. 3. Direct start test only need to press the OK button, the tester can automatically make an appropriate termination voltage according to the battery full charge voltage, and will start flashing three times to enter the test. If you need to manual set termination voltage, only need to pressing + or - buttons to modify under battery voltage display state, the termination voltage display beginning with P, behinds means voltage vaule, voltage resolution 0.1V, after setting up pressing the OK button to start testing. 4. After the start of the test, the tester will turn on the control load of the electronic switch, the test data will rotation display between release capacity (Ah) current discharge current (A) and battery voltage (V). When the battery voltage reaches the setting termination voltage, load control switches off the tester, data stays in capacity (Ah) and the corresponding indicator flashes quickly together, at this time the display is the actual capacity of the discharge capacity of the battery, press OK button to stop flashing allows stable data display, press again OK button to return to the power-on state, now you can replace the battery to test the next section. Error codes and their meanings: Err1: Battery voltage is above 15V Err2: Battery voltage is lower than the termination voltage Err3: Battery can not afford to load discharge current or the circuit resistance is too high Err4: Overcurrent (current exceeds 3.1A) Package includes: 1 x ZB2L3 Battery Capacity Tester 1 x Resistor More Info

The meaning and processing method of error code Err*: Err1: the battery voltage is too high, please confirm that the battery voltage is lower than 8.5V before test. Err2: the battery voltage is too low (below the set value of the termination voltage) please confirm the battery voltage and reset. If the battery is connected reversed and the four wire mode voltage measurement is not connected or connected to the reverse is also display Err2. Err3: the battery does not support setting discharge current or circuit resistance is too high, please use a smaller current to test battery, and to ensure that the cell line is thick and short, between the electrode contact is good. Err4: power tube damage, the problem generally occurs after the bad transformation, can replace the power tube, substitute models have P75NF75, etc.. Err5: beyond the test power constraints. this status is only possible when the power limit function is turned on (LPon) under on behalf of the set conditions the discharge power is more than 12W, the tester to prevent heat overheating and take protective measures. Users can DIY yourself (to increase the heat sink or installation of fans) and enter the function setting menu to close the power limit (LPoF) now you can use more than 12W power. Err6: the power supply voltage is out of range, when the power supply voltage is lower than 11V or higher than 14V, the test instrument under booting will show the error code, please replace the appropriate voltage power supply.. Note: when display the Err1-Err5, press any key to return to the initial state. Package includes: 1 x Lithium Battery Tester (Test tools does not includes) More Info
