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 quality
Material: Electrical components
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 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:
1. The first test should be a fully charged battery
2. 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.
3. Direct start test needs only one press of the "Ok" button, the tester
can automatically develop an appropriate termination voltage for 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.
4. After the start of the test the tester will control the load of the
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, 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 again to return to the
the power-on state can just replace the battery test in 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 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 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 OV) will show 0
