Features
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 get 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.
Instructions
1. The first test should be 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 need only one press of the inchOKinch 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 inch+inch or inch-inch buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the inchOK inchstart testing.
4. 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, 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 inchOKinch to terminate flashing allows stable data display, press again inchOKinch 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:battery voltage is lower than the termination voltage
Err3:Battery can not afford to load or discharge current line too much resistance
Err4:overcurrent (current exceeds 3.1A)
Package Included
1pcs Battery Capacity Meter Tester
2pcs load resistors
