Capacity Meter Discharge Tester 18650 Li-ion Lead-acid 1.5-12v

ZB2L3 capacity tester discharge type 1.2-12V external load capacity of the and tests 18650
Tools, single-function, by controlling the load off and get real-time integrated discharge current capacity results
Maximum 15V 3A discharged through the discharge voltage and current, itself does not discharge
Maximum capacity statistics 9999Ah (9999000mAh)
Automatically identify and develop appropriate termination voltage can also be manually adjusted

Specifications:
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 capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, 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:
1. The first should be fully charged .
2. Connect the 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 supply (not available desktop or laptop USB powered), then the voltage.
3. Direct start need one press of the "OK" button, the tester can automatically develop an appropriate termination voltage of the full charge voltage, and will start flashing after the three times. Need to develop termination voltage when the 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.
4. After the start of the the tester will control the load of the electronic switch is turned on, the data that the process will release capacity (Ah), current discharge current (A) and voltage (V) between the wheel was. When the voltage reaches the set cut-off voltage, 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 is discharging capacity, about the press "OK" to terminate flashing allows stable data display, press again "OK" button to return to the -on state can just replace the the section ......

Error codes and their meanings:
Err1: voltage is above 15V
Err2: voltage is lower than the termination voltage
Err3: can not afford to load or discharge current line 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 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

package include:
1 x 1.5 ~ 12V capacity tester
2 x load resistors
